A comparison of services so you can find the one that works for you.
Comparison pages are usually written by whoever “wins” the comparison. I'd love for you to use SigFetch, but it might not be the right answer for you. I'm trying to share the honest answers, so every number below was taken from the other vendors' own pricing pages, last re-checked in September 2026. It may contain errors, and I am not claiming this to be 100% accurate. That's why I noted where the data came from.
TLDR: SigFetch is the only tool here where unlimited sending and the API cost nothing. It is also the newest and least certified tool shown here. What you pick depends on what you need. SigFetch was built for what I needed, and I suspect others need it too, which is why I launched it in the first place.

Maybe another service is better for you
Pick the right tool for the job at hand.
Pick DocuSign
if you're an enterprise with a compliance checklist: it has the deepest certification stack (SOC 2, ISO 27001, FedRAMP), HIPAA BAAs, online notarization, and integrations with practically everything. You pay for all of that, and the Standard plan still caps you at 100 envelopes per user per year.
Pick Documenso
if open source plus certifications is your bar: it's AGPL-licensed, self-hostable, and SOC 2 compliant, with EU signature levels on its roadmap. The hosted free tier is 5 documents a month, so real usage means a paid plan.
Pick OpenSign
if you want open source and an unlimited free cloud tier: on raw free sending it's the closest thing to SigFetch on this page. API access, webhooks, and bulk send sit behind the paid plans, and it doesn't advertise SOC 2 or ISO certification.
Pick SignWell
if you want a cheap, certified paid plan: $10/month gets unlimited documents from a SOC 2 Type II vendor that will sign a HIPAA BAA, and its pay-as-you-go API pricing is genuinely developer-friendly.
Pick Dropbox Sign
if you live in the Dropbox ecosystem or need its certification set: SOC 2/3 and ISO 27001/27018, with HIPAA available on annual plans. The API is a separate, meaningful line item.
Pick SigFetch
if you want easy, unlimited sending, multi-signer routing, a tamper-evident audit trail, and a real REST API with webhooks for devs — all for zero dollars — and you don't need special certifications: no SOC 2, no HIPAA, no notarization.
