Six small data tools with real output, plain prices and stated limits
Echo Lab Tools documents six pay-per-result data tools that run on the Apify platform: an App Store rank tracker, a bulk domain expiry and SSL checker, an Apple Podcasts charts scraper, a jobs scraper for six public ATS job boards, a sitemap URL extractor and a website tech stack detector. Each one reads official public endpoints, needs no login, and returns JSON you can pull from an API, a schedule or an AI agent.
Every page below shows output copied from a real run on the Apify platform (with the run ID), a field table, a worked price example, five concrete limits, copy-paste API code, and an honest comparison with the usual alternatives, including when you should use something else.
App Store Rank Tracker
Keyword and top-chart ranks for your app and competitors, any country, from Apple's public feeds. One row per app × keyword/chart × country.

Bulk Domain Expiry & SSL Checker
Up to 5,000 domains per run: RDAP expiry and registrar, SSL validity and days left, DNS, SPF/DMARC, with warning codes for alerts.

Website Tech Stack Detector

How pricing works
All six tools are priced per result on Apify: you pay a fixed amount for each row saved to the dataset, plus an Actor start fee of $0.00005 per run. Apify platform usage (compute, memory) is included in that price, so the cost of a run is simply rows × unit price. There is no subscription and no minimum. You can set a maximum cost per run in Apify's run options and the tool stops cleanly at the limit.
Who makes these
Echo Lab is a small independent publisher. The tools are built and maintained by us, and the pages on this site are written from the tools' source code and from real run output. We do not publish user counts or testimonials because the tools are new; when there is something real to show, it will be here. Bug reports and field requests go to the Issues tab of each tool on Apify.
