Dataset Changes Since Last Run: New, Changed, Removed Rows

LLM Dataset Processor

dusan.vystrcil/llm-dataset-processor

Allows you to process output of other actors or stored dataset with single LLM prompt. It's useful if you need to enrich data, summarize content, extract specific information, or manipulate data in a structured way using AI.

Sitemap Change Orchestrator

tri_angle/sitemap-change-orchestrator

Monitor website sitemaps for new, updated, or removed URLs. Integration with the Website Content Crawler (WCC) allows feeding only relevant URLs. This ensures your web crawls are efficient, targeted, and resource-optimized, keeping your datasets fresh for any application.

Compare 2-10 Apify datasets to detect changes, new/removed records, and duplicates. Features field-level diffs, smart merging, schema validation, data cleaning, and anomaly detection. Perfect for price monitoring, lead deduplication, and data quality tracking.

Watch any website's sitemap and get one row per change: new pages, removed pages, optional lastmod updates. See competitors' new products, content clusters and landing pages the day they ship. Pay only for changes; quiet sites cost nothing. Keyless, no proxy.

Dataset Transformer — Filter, Dedupe, Sort & Reshape Data

nexgensignal/dataset-transformer-api

Transform Apify datasets or JSON / CSV links: filter rows, remove duplicates, sort, flatten nested fields, unwind lists, pick and rename columns. Merge several datasets into one clean result for export as JSON, CSV or Excel. Part of NexGen Signal — data tools and official-source data products

Output to Dataset

njoylab/apify-output-to-dataset

Merges outputs from multiple actors into a single dataset. Execute actors in series or parallel, combine data from datasets, key-value stores, webhooks, and export the final output in various formats.

Dataset Change Monitor

egra_van/dataset-change-monitor

Compare every scraper run with the previous one and get only new, changed and removed items, with field-level before/after diffs. Alerts via Telegram, Slack, webhook or email. Works with any Apify Actor, dataset, JSON or CSV.

DataCite DOI Monitor - Research Datasets & Metadata Changes

maydit/datacite-dataset-doi-monitor

Find dataset DOIs through DataCite and track version, rights and metadata changes. Export stable DOI identities and source links for dataset discovery and provenance reviews.

Checks a list of URLs and returns only the pages whose content changed since the last run: unified diff, added/removed lines, SHA-256 hashes. Optional CSS selector, keyword triggers and ignore regexes. Plain HTTP, respects robots.txt. $0.001 per URL checked, $0.005 per change.
