All In One Username Availability Checker

🔎 All In One Username Availability Checker – Check Handle Availability Across 85+ Platforms

The All In One Username Availability Checker tells you, in a single run, whether a username is free or already taken across more than eighty-five social, creative, developer, commerce and messaging platforms. Type one handle, choose "All", and get back a clean row for every platform showing its availability status and — where the handle is already claimed — a direct link to the existing profile.

Picking a handle is a one-time decision with a long tail of consequences. A name that is free on X but taken on Instagram, GitHub and Substack forces years of inconsistent branding, mismatched links and confused audiences. This username availability checker collapses what would otherwise be eighty-five manual signup attempts into one query, so you can shortlist names that are actually available everywhere before you commit to one.

📊 What Data Can You Extract with This Username Availability Checker?

Every dataset item represents one platform's verdict on the handle you searched. Four fields, no nesting.

Category	Fields	What it gives you
🆔 Record identity	id	A unique identifier for the individual check, useful as a primary key when loading results into a database
🌐 Platform	platform	The name of the platform this row reports on, for example github, reddit or medium
✅ Availability verdict	status	Available, Not Available, or Unknown where a platform cannot be checked reliably
🔗 Existing profile	profile_url	The URL of the profile that already holds the handle, populated when the status is Not Available
📥 Query context	driven by keyword and platform inputs	Whether the run covered every supported platform or was narrowed to a single one

The field that changes how you work is profile_url. A plain "taken" answer leaves you guessing whether the handle belongs to an active account, a dormant one, or a squatter. Because the checker returns the actual profile address whenever a handle is claimed, you can open the link and judge immediately whether the name is genuinely lost or worth pursuing.

🌟 Key Features of the Username Availability Checker

Feature	Description
🌍 85+ platform coverage	One run checks a handle across social networks, developer platforms, creative portfolios, marketplaces, streaming services and messaging apps
🎯 Single-platform mode	The platform input accepts any one supported platform name, so you can check just GitHub, just Reddit or just Instagram when that is all you need
🔗 Profile URL on collisions	When a handle is taken, the checker returns the URL of the profile holding it rather than a bare boolean
🚦 Three-state status	Available, Not Available and Unknown — the third state is reported honestly rather than being guessed at
🔀 Automatic proxy rotation	Requests are routed through rotating proxies automatically, with retries, so transient blocks do not silently corrupt results
📐 Flat four-field schema	Every row has the same four scalar keys, which means CSV exports and database loads need no flattening
🔢 Stable record IDs	Each check carries a unique id, making it straightforward to deduplicate or upsert results across repeated runs
⚡ No headless browser	The checker uses HTTP requests and lightweight HTML parsing rather than rendering pages, keeping runs fast
📤 Full Apify export options	Results are written to an Apify dataset and can be downloaded as JSON, CSV, XLSX, XML or HTML, or fetched via API

🚀 Why Choose This Username Availability Checker?

Breadth in a single query. Checking a handle by hand means opening a signup form on every platform you care about and reading the error messages. Covering eighty-five platforms that way is a morning's work per candidate name. Here it is one run, and comparing five candidate names is five runs.

Honest Unknown results. Some platforms cannot be probed reliably without an account, and a checker that guesses in those cases is worse than useless — it produces confident answers that are sometimes wrong. This one reports Unknown for platforms such as Instagram and Twitch instead of inventing a verdict, so you know exactly which handles still need a manual look.

Actionable collision data. The profile_url field turns "taken" into something you can act on. An abandoned account with no posts is a very different obstacle from an active profile with a large following, and you can only tell the difference by looking at the profile the checker hands you.

Results shaped for tooling, not for reading. The output is a flat dataset with stable identifiers, so it slots into spreadsheets, brand-monitoring dashboards and internal naming tools without transformation. Run it on a schedule and you have a change log of when handles free up.

📥 Input

The username availability checker takes the handle to check and, optionally, a single platform to narrow the search to.

{
  "keyword": "emilywritespoem",
  "platform": "All"
}

🔧 Username Availability Checker Input Fields

Field	Type	Required	Default	Description
keyword	string	✅ Yes	emilywritespoem	The username to search for across platforms.
platform	string (enum)	❌ No	All	Which platform to check. Choose All to check every supported platform, or pick a single one from the list — options include X, Reddit, Github, Medium, Twitch, Instagram, Myanimelist, Anilist, Gumroad, Youtube, Bluesky, Linktree, TikTok, Pinterest, LinkedIn, Tumblr, Vimeo, SoundCloud, Spotify, StackOverflow, Quora, Telegram, Discord, Substack, Patreon, Etsy, Ebay, Behance, Dribbble, Deviantart, Goodreads and many more.
proxyConfiguration	object	❌ No	—	Optional proxy configuration object. Proxy rotation is handled automatically by the Actor, so this can normally be left untouched.

💡 Input Examples

Full sweep across every supported platform

{
  "keyword": "acmestudio",
  "platform": "All"
}

Check a single platform only

{
  "keyword": "acmestudio",
  "platform": "Github"
}

Checking a personal brand handle

{
  "keyword": "emilywritespoem",
  "platform": "All"
}

---

📤 Output

Each item is one platform's verdict on the handle. A run with platform set to All produces one item per supported platform.

{
  "id": "a7f3c1d9e2",
  "platform": "github",
  "profile_url": "https://github.com/emilywritespoem",
  "status": "Not Available"
}

An available handle returns an empty profile_url, because there is no profile to link to:

{
  "id": "b2e8a04c7f",
  "platform": "medium",
  "profile_url": "",
  "status": "Available"
}

🧾 Username Availability Checker Output Fields

Field	Type	Description
id	string | integer	Unique identifier of the check record
platform	string | null	The platform this row reports on
profile_url	string | null	URL of the existing profile page, populated when the handle is already taken
status	string | null	Available, Not Available, or Unknown where the platform cannot be checked reliably

Note the relationship between the last two fields: profile_url is only meaningful when status is Not Available. Treat an empty profile_url alongside an Available status as the normal, expected combination.

💻 How to Use the Username Availability Checker (Step by Step)

Step 1: Open the Username Checker on Apify

Sign in to your Apify account and open the All In One Username Availability Checker Actor. The Actor runs entirely on Apify's infrastructure — there is nothing to install, no proxy credentials to source and no platform accounts to create. The page gives you an input form, a live log and a dataset tab where results appear as each platform is checked.

Step 2: Enter the Username You Want to Check

Type your candidate handle into the Username field. Enter it exactly as you intend to register it, without a leading @. Case generally does not matter for availability, but the exact character sequence does: acme_studio and acmestudio are entirely different handles and will return entirely different results.

Step 3: Decide Between All Platforms and One

Leave Platform on All for a full sweep — this is the right choice when you are evaluating a name for a new brand or persona and need to know where it survives. Select a single platform instead when you already know which network matters and want a fast, focused answer, for example checking only GitHub before naming an open-source project.

Step 4: Run the Checker and Follow the Log

Press Start. The log reports each platform as it is checked, along with the verdict. Because requests go out through rotating proxies with retries, an individual platform that responds slowly or rejects the first attempt is retried rather than being dropped. Platforms that ultimately cannot be reached are logged and skipped.

Step 5: Read the Status Column

Open the Dataset tab and sort by status. The Available rows are your opportunity list. The Not Available rows come with a profile_url you can click to inspect the incumbent account. The Unknown rows — typically Instagram and Twitch — are the handful you should verify manually on the platform's own signup form.

Step 6: Compare Candidate Names Side by Side

Naming decisions are comparative. Run the checker once per candidate handle, export each dataset, and stack them in a spreadsheet with platform as the row key and each candidate as a column. The name with the most Available verdicts across the platforms you actually care about is usually the right answer, and the comparison takes minutes.

Step 7: Export, Automate or Monitor

Download results as CSV or JSON, or connect the Actor to a scheduler. Handles do get released when accounts are deleted, so scheduling a weekly run against a handle you want and alerting on any status flipping to Available is a practical way to catch a name the moment it frees up.

🔌 API Access & Integrations

Run the username availability checker and get the results in the same request:

curl -X POST "https://api.apify.com/v2/acts/scrapers-hub~all-in-one-username-availability-checker/run-sync-get-dataset-items?token=YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "keyword": "emilywritespoem",
    "platform": "All"
  }'

The same call with the official Python client:

from apify_client import ApifyClient

client = ApifyClient("YOUR_TOKEN")

run = client.actor("scrapers-hub/all-in-one-username-availability-checker").call(
    run_input={
        "keyword": "emilywritespoem",
        "platform": "All",
    }
)

available = []
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    if item.get("status") == "Available":
        available.append(item["platform"])

print("Free on:", ", ".join(available))

Results can also be pushed automatically to Zapier, Make, Google Sheets and Slack, or to any endpoint you control using Apify webhooks that fire when a run completes.

💡 Best Use Cases for Username Availability Data

🏷️ Brand Naming and Launch Preparation

Before a company, product or podcast name is locked in, run every shortlisted handle through the availability checker. A name where status is Available across all the platforms in your channel plan is worth far more than one that is only free on your primary network, because consistent handles are what make a brand searchable.

🎨 Creator and Personal Brand Setup

Creators building an audience across several networks need one recognisable handle. Sweeping all platforms in one run shows exactly which candidate survives everywhere, and the profile_url values reveal whether the collisions are dormant accounts or active competitors for the name.

🛡️ Brand Protection and Squatter Detection

Run your own official handle and its near-miss variants. Any variant returning Not Available with a profile_url you do not recognise is a candidate impersonation or squatting account, and the link goes straight to your trust-and-safety team for review.

📡 Handle Monitoring and Release Watching

Desirable handles occasionally free up when accounts are deleted or purged. Scheduling a recurring run against a specific keyword and watching for status to change from Not Available to Available gives you an early alert rather than a lucky discovery.

🧑‍💻 Open-Source Project and Package Naming

Before naming a library, check the handle on developer-facing platforms. A Github result of Not Available for your intended organisation name is a blocking problem worth discovering before the README is written, not after.

🔍 OSINT Footprint Indication

Because Not Available rows include a profile_url, a full sweep of a known handle doubles as a footprint indication: it shows which platforms already host an account under that name and gives you the addresses to review. Treat matches as leads requiring corroboration, not as proof of identity.

📋 Agency Client Onboarding

Agencies setting up social presence for a new client can run the client's preferred handle once and deliver a complete availability report as a spreadsheet. It turns a tedious manual audit into a two-minute deliverable and starts the naming conversation from evidence.

⚙️ Tips for Better Username Availability Checking

• Check variants alongside your first choice. Underscore, dot and short-suffix versions of a handle often survive where the plain form does not. Running three or four variants gives you a realistic set of options rather than a single disappointment.
• Treat Unknown as a to-do, not a result. Platforms reported as Unknown — Instagram and Twitch among them — need a manual check on their own signup page. Do not assume availability from the absence of a definitive answer.
• Open the profile_url before writing a name off. An account with no avatar, no posts and no followers is a very different obstacle from an active one, and some platforms release inactive handles on request.
• Use single-platform mode for speed. If only one network matters for the decision at hand, set platform to that network. A single-platform run finishes far quicker than a full eighty-five-platform sweep.
• Re-check before you commit. Availability changes constantly. Run the checker again immediately before registering, because a handle that was free last week may have been claimed since.
• Keep every run's dataset. Storing results over time gives you a history of when specific handles were taken or released, which is genuinely useful for both monitoring and disputes.

🛠️ Troubleshooting

Why do Instagram and Twitch always show Unknown? Those platforms cannot be probed reliably without an authenticated session, so the checker reports Unknown rather than guessing. This is deliberate — a wrong confident answer would be worse than an honest absence of one. Verify those two manually.

A handle shows Available but the platform refuses my registration. Platforms apply their own additional rules: reserved words, trademark holds, minimum lengths, character restrictions and previously-deleted-account cooldowns. The checker reports whether a public profile exists, which is not identical to whether registration will be permitted.

Some platforms are missing from my results. The run emits a row per platform that was successfully checked. If a platform is absent, its request did not complete on that run — usually a transient block or timeout. Re-running normally fills the gap.

profile_url is empty on a row marked Not Available. The URL is only populated for platforms with a known public profile-URL pattern. A taken handle on a platform without such a pattern still reports Not Available correctly, but has no link to offer.

The run is taking a long time. A full sweep contacts a large number of platforms, each with retries on failure. If you only need one platform, use the platform input to narrow the run — it is dramatically faster than checking everything.

❓ Frequently Asked Questions About Username Availability Checking

What does the All In One Username Availability Checker do? It is a username availability checker that takes a single handle and reports whether it is free or taken on more than eighty-five platforms, returning a status per platform plus the profile URL of any existing account holding the name.

How many platforms does it check? Over eighty-five, spanning social networks, developer platforms, creative portfolios, marketplaces, streaming, blogging and messaging services. You can also target any single one of them using the platform input.

Can I check more than one username at a time? The keyword input takes one handle per run. To compare candidates, run the checker once per name and combine the exported datasets — the flat schema makes stacking them in a spreadsheet trivial.

What do the three status values mean? Available means no public profile was found at that handle. Not Available means an existing profile was detected. Unknown means the platform could not be checked reliably and needs a manual verification.

Does the checker give me the URL of the account that took my handle? Yes, whenever the platform has a known public profile-URL pattern. The profile_url field is populated on Not Available rows so you can inspect the incumbent account directly.

Is Available a guarantee that I can register the name? No. It means no public profile was detected. Platforms also enforce reserved-word lists, trademark protections, length and character rules, and cooldowns on recently deleted accounts.

Do I need accounts or API keys on the platforms being checked? No. The checker requires no platform credentials, no cookies and no logins. You only need an Apify account to run the Actor.

Does it need proxies configured? No. Proxy rotation and retries are handled automatically, which is what keeps results consistent across a large number of platforms in one run.

How current are the results? They reflect the moment the run executed. Handle availability changes continuously, so re-run immediately before registering anything important.

Can I run the availability checker on a schedule? Yes. Apify's scheduler supports any cron expression, which makes recurring monitoring of a specific handle straightforward. Pair it with a webhook to be alerted when a status changes.

What export formats are supported? JSON, CSV, XLSX, XML, RSS and HTML from the Apify dataset UI, plus programmatic access through the dataset API endpoint.

Why does the same handle show as taken on one platform and free on another? Handles are allocated independently by each platform and are not globally unique. This is precisely why a cross-platform username availability checker is useful — consistency across networks cannot be assumed.

Can I use this for brand protection monitoring? Yes. Check your official handle and its plausible misspellings on a schedule; any variant returning Not Available with an unfamiliar profile_url is a candidate impersonation account worth reviewing.

Does the checker use a headless browser? No. It works through HTTP requests and lightweight HTML parsing, which is why a broad multi-platform sweep completes without the overhead of page rendering.

What is the id field for? It is a unique identifier for each check record. It is most useful as a primary key when loading results into a database or when deduplicating across repeated runs.

⚖️ Disclaimer

This username availability checker works only with publicly accessible information. It checks whether a public profile page exists for a handle and, where one does, returns its public address. It does not log in to any platform, bypass authentication, access private profiles or retrieve content behind a login wall.

You are responsible for how you use the results. Availability data can point to accounts belonging to identifiable individuals, so if you process it in a jurisdiction covered by the GDPR, the UK GDPR, the CCPA or similar privacy law, you must establish a lawful basis, respect data-subject rights and apply appropriate retention and security controls. Using the checker to support harassment, impersonation, stalking or targeted intimidation is prohibited.

Respect the terms of service of every platform involved and comply with all applicable laws in your jurisdiction. An Available status is an observation, not legal or trademark clearance — check trademark registers separately before adopting a name commercially.

If you believe data about you has been collected through this Actor and you would like it removed, contact scraperhubapi@gmail.com and we will action the request.
