Fast and reliable screenshot API built to handle millions of screenshots a month.
PDFops is a hosted PDF API built for edge runtimes (Cloudflare Workers, Vercel Edge, Deno, Bun). Two endpoints, one HTTP call each: Fill AcroForm fields in an existing PDF from a JSON map of field → value. Merge multiple PDFs into one. What's different from cloud PDF platforms: no headless...

As answered by people managing ScreenshotOne and PDFops.dev.
ScreenshotOne's answer
Developers who value their time and want to outsource boring tasks of dealing with screenshot automation to focus on their core business features.
PDFops.dev's answer:
Developers and AI-application builders who need to fill AcroForm fields or merge PDFs programmatically — especially teams deploying on edge runtimes who cannot run a headless browser or native PDF binaries inside a V8 isolate.
PDFops.dev's answer:
PDFops started from a recurring edge-runtime pain: nearly every PDF API assumes a server with a headless browser or native libraries, which you cannot run inside a V8 isolate like Cloudflare Workers or Vercel Edge. PDFops is the deterministic write-and-merge primitive built for that environment — one HTTP call, predictable bytes out.
PDFops.dev's answer:
TypeScript on the Hono web framework, with a pure-JavaScript PDF engine (a maintained pdf-lib fork) and no native dependencies. That combination runs inside V8 isolates, which is what lets PDFops execute on edge runtimes such as Cloudflare Workers and Vercel Edge.
PDFops.dev's answer:
No per-call tax: $0.004 per call versus the ~$0.10 typical of incumbent hosted PDF APIs (~25× cheaper). It runs at the edge instead of round-tripping to a vendor cloud, the output is deterministic (hashable and cacheable), and there is a free, no-signup tier plus a PDF field Inspector for exploring a document’s AcroForm fields before writing any code.
PDFops.dev's answer:
Deterministic, byte-identical PDF output from a single HTTP call — and it runs from edge runtimes (Cloudflare Workers, Vercel Edge, Deno, Bun) with no headless browser and no native dependencies. The same input always yields the same bytes, so you can hash, cache, diff, and sign the result.
