Slack Marketplace · Unique Developer Emails

Export unique Slack Marketplace publishers — public email, website, categories and app portfolio — one vendor per row, not one row per listing.

No login. No Slack API key. No workspace access.

Who is this for?

You are…	Typical goal	Suggested setup
Partnership / alliances at a SaaS	Unique publishers already selling into Slack, not duplicate app rows	Search your niche (security, zoom) then sort by appCount
Collab / security / HR SaaS	Vendors whose customers already live in Slack	Category (Security & Compliance, HR, Productivity) + Require public email = Yes
Outbound / SDR	CRM-ready inbox and company site	Publishers — Outreach view, CSV
Market research	Who publishes several Slack apps	Paid Full catalog, raise Max vendors

What you get by default: unique publisher, public support inbox when listed, website origin, categories, sample listing icon — only fields the Marketplace already shows. Slack-built apps are skipped unless you turn that filter off.

Typical fill (public zoom slice, Aug 2026): 48 listings collapsed to 43 unique vendors; 8 exported with a public inbox (e.g. Zoom zoom-integrations@zoom.us, 4 Zoom apps → 1 row). Slack does not publish install counts or a developer display name.

When the directory already has the inbox: this Actor does not crawl the publisher’s marketing site. Slack listings typically publish a support email on the page itself.

How to scrape Slack Marketplace publishers

1. Open this Actor in Apify Console.
2. Step 1 — Mode: leave Search (a niche) or switch to Full catalog (every unique publisher, paid). Catalog ignores keyword and category.
3. Step 2 — Search (Search mode only): keep zoom, or paste https://slack.com/marketplace/A5GE9BMQC. Optionally pick a category.
4. Leave Max vendors at 20 for a first run, then raise it. Full catalog: raise toward 5,000.
5. Click Start. Download JSON / CSV / Excel. Use Publishers — Outreach for the inbox; Overview for who ships several apps.

In Search mode, query or category is required. Full catalog is paid Apify plans only.

See the Input tab for the visible options (proxy is optional and hidden).

Ready-made examples (published tasks)

Example	What you get
Find Slack security app publishers with emails	Unique Security & Compliance vendors, public inbox, CRM-ready
Export Slack productivity app vendors for CRM	Productivity category, one publisher per row
Refresh Slack publisher contacts from an app URL	Paste a listing URL, get the vendor file
Slack AI app publishers for cold outreach	AI Apps & Assistants niche, outreach view

What data can this Slack Marketplace scraper extract?

Field	Why it matters for ICP
developerEmail, emails	Public inbox on the listing
developerWebsite, developerDomain	Company site + clean host for CRM match
developerName	Company inferred from the inbox / website host (Slack does not publish a developer display name)
supportUrl, privacyPolicyUrl	Other public ways in
categories, appCount, appNames	Portfolio in this run
sampleAppName, sampleAppIcon, listingUrl	Sample listing + logo
sourceQuery, scrapedAt	Run metadata

Not extracted (and not invented): private Slack workspace contacts, guessed emails from the marketing site, install counts or review scores (Slack does not publish them on the public listing).

Two apps that share the same support-email domain stay one lead.

How much does it cost to scrape Slack Marketplace publishers?

This Actor uses pay-per-event pricing. Actor start is $0.00005 (Apify default — first 5 seconds of compute included). You only pay per unique publisher written to the dataset. You are not charged per app listing. Paid Apify plans get a lower price per vendor.

Free plan: a run stops at 20 vendors — enough to test. Keyword / category: paid plans can raise Max vendors up to 2,000. Full catalog (paid only) goes up to 5,000 unique publishers.

	Free	Bronze	Silver	Gold	Platinum	Diamond
Per unique vendor	$0.001	$0.0009	$0.0008	$0.0007	$0.0006	$0.0005
20 vendors (Try)	$0.02	$0.02	$0.02	$0.01	$0.01	$0.01
1,000 vendors	$1.00	$0.90	$0.80	$0.70	$0.60	$0.50
Full catalog (~1,500–2,000 unique publishers)	~$1.50–2.00	$1.35–1.80	$1.20–1.60	$1.05–1.40	$0.90–1.20	$0.75–1.00

Totals include the $0.00005 start. Live Slack Marketplace scrapers on Apify charge per app listing: jungle (17 users) $0.10 start + $1 / 1k apps; crawlerbros ~$4.33 / 1k; dadhalfdev $9 / 1k; lead.gen.labs ~$20 / 1k. Same $1 / 1k sticker as jungle — but here two apps from the same publisher are one charge, and start is $0.00005 not $0.10. A 1,000-vendor file is $1 on Free — Zoom’s four apps count as one row.

Set Max vendors and, on Apify, a max total charge so a run cannot exceed your budget. A row with an empty email still counts if Require public email is No.

Default memory is 512 MB (HTTP only, no browser).

Is it legal to scrape Slack Marketplace?

This Actor only accesses data that Slack makes publicly available on slack.com/marketplace listing pages (support email, website, categories the publisher chose to show). As with any data containing personal information, ensure your use complies with GDPR and relevant regulations. Do not scrape personal data unless you have a legitimate reason to do so.

Performance

HTTP only, 512 MB default, 4h timeout. A 20-vendor keyword run typically finishes in under two minutes. Full catalog (~2,600 listings) is a longer paid job — unique vendors are fewer than listings because several apps share one publisher.

FAQ

Why is there no developer name on some rows? Slack does not publish a company display name on public listings. The Actor uses the inbox / website host (e.g. zoom.us → Zoom) or the sample app title when there is only one app.

Why skip Slack-built apps? Incoming Webhooks and similar Slack-owned listings have no third-party inbox. Turn Skip Slack-built off if you want them.

Do I need a Slack token? No. Public Marketplace pages only.

Do I pay per app? No. Two apps from the same publisher = one charge.

Is a proxy required? No. Enable Apify Proxy only if you get blocked.
