Anvil PDF Filling API
Easily generate PDF documents from pre-defined PDF templates with JSON data. Enable your users to create PDFs and manage their document templates using a browser-based drag-and-drop PDF editor to reduce development and support costs.
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.

PDF Generator API's answer

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.
PDF Generator API's answer
From small to large companies we can provide cloud infrastructure for PDF creation and multiple other PDF services. We also provide dedicated and on-prem infrastructure for Enterprises worldwide.
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.
PDF Generator API's answer
It seems the PDF customization and generation tools market is quite abundant and there are many companies battling it out for the attention of customers. However, we also see that PDF Generator API has some features that are unmatched by any of the other platforms. Among other features, we are the only ones that offer our clients support video calls and last, but not least โ we are by far the most cost competitive platform among the whole bunch.

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.

Our HQ is in Estonia. We provide PDF creation for hundreds of client for more than 10 years. We are part of PDF Association and ISO Certified subject, which highlight our commitment to the highest security standards.
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.

Bigbank, DFDS, Veeqo.
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.
We did integration with PDF API and it is working as expected, we use forms to collect the data as well. Automated the invoice creation with their API. Great editor, btw.
