Buildformswithoutbuildingabackend.
Point any form at one durable endpoint. Postness validates, stores, notifies, and delivers every submission. No servers to run. Nothing ever lost.
No credit card. 10,000 submissions free every month.
Trusted by teams who cannot afford to lose a submission
One endpoint. Every form.
Send a request. Watch it land. Every submission is accepted at the edge, validated, and committed to durable storage before we ever return a response.
A submission must never be lost.
That is the whole promise. From the moment a request hits our edge to the moment it reaches your inbox, every submission is durable, traceable, and recoverable.
Write-ahead durability
We fsync every submission to a replicated log before returning 202. If we accepted it, it exists.
Automatic retries
Delivery and webhooks retry with exponential backoff for 24 hours. Failures queue, they never vanish.
Complete audit trail
Every state change is recorded and timestamped. You always know exactly what happened to a submission.
Everything a form needs. Nothing it doesn't.
Validation, routing, notifications, and controls come standard. Wired into auth, tenancy, and roles from the first request.
Schema validation at the edge
Define the shape you expect. Postness stamps a verdict before a submission is ever stored, so bad data never reaches your inbox.
{ "email": "email", "rating": "int(1,5)", "message": "string(max=2000)"}Notifications that reach you
Push, email, and Slack the instant a submission lands.
New contact submission from [email protected]
Webhooks and integrations
Fan out to your stack with signed, retried webhooks.
Spam and abuse guards
Honeypots, rate limits, and quota guards keep noise out and costs predictable.
Teams, roles, and tenancy
Every project is isolated. Roles decide who reads, exports, or manages submissions.
Observable by default
Live delivery status, structured logs, and a full audit trail for every submission. When something happens, you can see exactly what and why.
From submit to inbox, in real time.
Your form posts once. Postness accepts, stores, and streams it to every destination you connect, live.
Ship your first form in five minutes.
Plain HTML, a one-line fetch, or a typed SDK. Copy the endpoint, point your form at it, and you are live. No SDK required, no lock in.
- Typed SDKs for JavaScript, React, and Python
- Idempotency keys and signed webhooks built in
- OpenAPI spec and copy-paste examples for every route
