Plain text files for HTTP, flows, WebSocket, MQTT, mocks.
Run them natively. Diff them in git. Keep secrets in .env.local.
No accounts, no cloud, no proprietary format.
Write requests in .http the same way you write code. Use @variables at
the top, ### Headings per request, JSON bodies in place. The whole workspace
is just files — drop it in a repo, commit, push.
Press ⌘R on a .mock file
and a local HTTP server boots up. Match by method & path, return JSON, latency, status —
everything templated. Subscribe to .mqtt, watch .sse streams,
.ws sessions, all in the same window.
Inherit base.env in dev.env. Override one key in
.env.local — auto-gitignored. .profile files compose entire
environment combos for QA, staging, your laptop. Secrets stay on disk.
Your tests live next to your code. Reviewers see request diffs in line. CI runs the
same files you ran locally. The .sendpad/ workspace is auto-gitignored,
so personal state never bleeds in.
These three constraints define the product. They're load-bearing. We've turned down features that would have broken them.
Your files live on your disk. No sync. No upload. No telemetry. Sendpad makes a network call only when you press Run — to the API you wrote.
Download, open, work. No signup. No password. No "verify your email." Pro is a license key you paste in Settings → License — that is the entire identity layer.
Pro is one-time $49. Pay once. Use forever. Lifetime updates included — no renewals, no recurring charges, no surprise auto-renew.
Eleven first-class capabilities, six free forever. Pro features unlock with a license key in Settings — no server, no account.
CodeMirror 6 with .http syntax, autocomplete, gutter run buttons. Open any folder, no project setup.
Chain requests, extract with JSONPath, assert results. Pipeline visualization + literate test reports.
Scripted send/receive in .ws files. SSE auto-detection with live event timeline. Filter, copy, replay.
Everything is a file. Diff in your terminal, review in your PR. .sendpad/ workspace auto-gitignored.
RFC 6265 per-environment jars. CookieManager modal. @cookies off directive when you need clean state.
Paste cURL, drop in OpenAPI. Copy any executed request as cURL with cookies. Markdown export for flow reports.
Boot a real HTTP server from .mock files. Unlimited routes, templated responses, @forward proxy to upstream.
Connect to any broker. QoS 0–2, retained, TLS. Topic tree, device simulator, scripted publish.
@extends in .env files. .profile composition for QA, staging, your laptop. Envs Manager diagnostics.
Side-by-side compare of two history entries. JSON-aware structural diff. Snapshot Testing with capture/replay.
@expect event, @extract event, @sse-reconnect. Treat event streams like any other test surface.
There are great tools out there. Here's where Sendpad fits.
Free to download and use. No account, no telemetry, no credit card.
