Anvil PDF Filling API
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.devPDFops.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.

I use Adblock Plus on Firefox, and what I had to do was add qualtrics.com to the "Allowlisted websites" area. Source: about 3 years ago
I had the same problem. It looks like it was related to my ad blocker (I use Adblock Plus). Adding qualtrics.com to its allowed list resolved the issue. Source: about 3 years ago
It doesnt matter really, However in some HIT's an ad blocker can actually keep the page from loading. I had a few instances where the page loaded nothing because I guess the ad blocker detected it as an ad. You can always whitelist worker.mturk.com and also qualtrics.com links in your ad blocker and still keep the ad blocker on. I use Ublock origin and I have the same links whitelisted so the ad blocker doesnt... Source: over 3 years ago
