What Web3Forms is
Web3Forms gives static site developers a single access key and a POST URL—popular on Hugo, Astro, and plain HTML repos.
It is intentionally simple: little dashboard ceremony, fast setup, community-friendly free tier.
How MuxForms differs
MuxForms ships a fuller dashboard inbox, per-form CORS allowlists, schema embed, and per-form webhooks on the standard plan.
Web3Forms wins on zero-friction experiments; MuxForms wins when the same backend must also serve a mobile app and three client WordPress sites.
Pricing and limits (honest)
Web3Forms Pro unlocks higher volume and features; check their current cap table before committing a client site.
MuxForms pricing is not per-key—it is one subscription covering unlimited forms once you subscribe.
When MuxForms wins
- You need searchable history across many forms and properties.
- Webhooks and notify email per form without juggling access keys per repo.
- Expo or React Native should write to the same inbox as the marketing embed.
When Web3Forms wins
- One personal static site and the free access-key tier covers your volume.
- You want the lightest possible setup and email is enough.

Common questions
- Is MuxForms a drop-in replacement for Web3Forms?
- For many contact and lead forms yes—match field names, update the endpoint or embed, and allow your site origin. Complex workflows may need a feature checklist.
- What about CORS errors?
- Browser embeds and client fetch require your production URL on the form allowlist. Server Actions and mobile JSON with the ingest secret do not use CORS.
- What does HTTP 403 mean?
- Disallowed origin, missing ingest secret, invalid submit token, paused form, or failed Turnstile. Read the JSON error message in the response.
- What does HTTP 422 mean?
- Validation failed—field names and lengths must match the schema defined in the MuxForms dashboard.
- When is Web3Forms still the better tool?
- See the “When Web3Forms wins” list on this page—we try to be honest when Web3Forms fits your workflow better.
- How does pricing compare?
- MuxForms is $9/month for unlimited forms on the paid plan. Use the comparison table above for Web3Forms's caps.
