Power On Labs

Small, reliable web utilities. Each Actor here does one job properly: sane defaults, predictable output, and no surprises in the bill.

Tech Stack Audit  — detect a website's technology stack with a real browser instead of guessing from HTML. ~280 technologies, plus the version and how old it is, which trackers actually fire, security headers, cookies set before consent — and the evidence behind every detection.

PDF to JSON Extractor  — turn any PDF into structured JSON. Tables come back as real rows and columns, headings and paragraphs in true reading order, plus metadata, form fields and key fields: invoice numbers, dates, totals, IBAN, VAT. Markdown output for RAG. Scanned pages and failed files are never charged.

Website Screenshot & PDF Generator API  — capture any web page as PNG, JPEG, WebP or PDF. Full-page, viewport or single-element screenshots. Cookie banners removed, ads blocked, lazy images loaded. Device presets, retina scale, dark mode, batch URLs.

• Pay per use. No subscription and no start fee. Failed inputs are never charged.
• Predictable output. One dataset row per input, with a direct file link, and a clear error message when something goes wrong. One broken input never kills the whole run.
• Built for pipelines. Structured JSON output, usable from the API, the Node.js and Python clients, or no-code tools like Make, n8n and Zapier.
• Maintained. Issues and reviews get answered. If an option you need isn't there, open an issue on the Actor and ask.
