No account
required.
Start locally. No signup wall, hosted workspace or mandatory telemetry stands between you and the first request.
LOCAL BY DEFAULT ↗LOCAL-FIRST API DEVELOPMENT
Ship the API.
Keep the
workspace.
Postly is the open-source Postman alternative without an account: a native Rust core, Git-friendly collections and a desktop/CLI workflow that stays close to your code.

TOML / GIT-NATIVE ↘
01One requestto first response
02One folderper workflow
03One repofor the project
Built for the moment
after “it works”.
WHY POSTLY / 02
Your API work
should be portable.
Keep the useful parts of an API client in the same place as the API itself: inspectable files, explicit environments and a repeatable command line.
No account
Git is the
workspace.
Human-readable TOML, one request per file and deterministic layouts make API workflows reviewable with ordinary diffs.
COMMIT THE CONTEXT ↗Desktop when
you look. CLI when
you ship.
Both surfaces share the same Rust request model, runner, environments and evidence-driven behavior.
ONE CORE / TWO MODES ↗THE WORKFLOW / 03
03A calm surface for
high-context work.
From first call
to repeatable proof.
Postly is shaped around the whole API-development loop, not only the send button.
Compose
Params, headers, bodies, cookies, common auth and variables in a durable request model.
Inspect
Pretty or raw responses, headers, cookies, timing, search and bounded local snapshots.
Prove
Assertions, scripts, iteration data, folder runs, JSON/JUnit reports and a local mock server.
Commit
Keep the collection beside the code, review it in Git and reopen the same project tomorrow.
ONE LOCAL SURFACE / 04
Meet the API
where it actually lives.
01REST / HTTP
Bodies, auth, cookies, redirects, TLS, proxy and response evidence.↗
02GRAPHQL
Structured queries, variables, operation names and schema introspection.↗
03STREAMING
SSE events plus reusable WebSocket text frames with bounded history and cancellation.↗
04gRPC
Local proto discovery, reflection, metadata and finite streaming calls.↗
P
Postly is early and ambitious. Compatibility is published as executable evidence, not a “100% compatible” badge.

There is no
account step.
Build from source today, initialize a project and make the first request. The repository documents the current release gates instead of pretending an unpublished package exists.
