PDFops is a hosted PDF API built for edge runtimes (Cloudflare Workers, Vercel Edge, Deno, Bun). Two endpoints, one HTTP call each:
What's different from cloud PDF platforms: no headless browser, no native binaries, and deterministic, byte-identical output for the same input โ so you can hash, cache, diff, and sign the result. It's callable directly from an edge function: POST a template plus data, get bytes back.
Built for developers and AI apps that need to write PDFs programmatically without operating a rendering service. Free tier: 100 requests/month per IP, no signup. Pro: $16 for 4,000 calls ($0.004/call) โ about 25ร cheaper per call than incumbent hosted APIs.
Also free, no signup: a PDF field Inspector (paste a PDF, see its AcroForm fields) and a live playground.

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 โ 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 (~25ร 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 documentโs AcroForm fields before writing any code.
PDFops.dev's answer
Deterministic, byte-identical PDF output from a single HTTP call โ 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.
PDFops.dev's answer
Developers and AI-application builders who need to fill AcroForm fields or merge PDFs programmatically โ especially teams deploying on edge runtimes who cannot run a headless browser or native PDF binaries inside a V8 isolate.

Its from typeform.com and it looks to be their own proprietary code, I couldn't see any specific libraries they were using. Source: almost 4 years ago
Not any social medias, not a single review on trustpilot, not a single piece of verifiable information that their thing is legit, nothing. And also the weird thing that I saw is when you go take their survey so they can take your commission, they sent you to a weird โtypeform.comโ link which apparently is a website that allowed them to have a web based platform they can use to create surveys without needing to...

What is the best way to implement quite complex, personality surveys into a flutter app? It`d be perfect if I could directly integrate typeform (typeform.com) et al, but haven`t found anything yet, except to embed it in a webpage... Any other ideas? Source: about 4 years ago
