Make the call.
Choose your method. Add parameters, headers, authentication, and a body. Set a timeout and send directly from your computer.
Build the request. Read the response. Keep your work close.
A local-first API workbench for Windows, with collections, environments, tests, and history. Start locally, without an account or a service to configure.
THE EVERYDAY ESSENTIALS
The tools you reach for every day,
in one focused desktop workspace.
Choose your method. Add parameters, headers, authentication, and a body. Set a timeout and send directly from your computer.
Inspect response bodies, headers, status, and timing. Format JSON or XML, check assertions, and revisit your local request history.
Organize collections and nested folders. Reuse environment variables, run collections, and move work with supported imports or encrypted backups.
A LOOK INSIDE
Your collections on the left. The request above. The response below. A practical workspace for everyday API testing.
LOCAL MEANS LOCAL
Free Local opens without signing in or connecting to an API Workbench server. Your saved requests, environments, and history live on your computer.
How your data is storedInternet-only endpoints still need an internet connection.
READY WHEN YOU ARE
Same app. Two bundles.
One simple Windows installer.
Your complete visual API workspace. Requests, collections, environments, tests, history, and local backups.
The same visual workspace, plus a local collection runner for your terminal. Both share one runtime.
A FEW GOOD QUESTIONS
No account is required for Free Local. Open, edit, organize, inspect history, and test reachable local APIs without API Workbench services. Requests to internet endpoints require a network connection.
On Windows, local data lives in %LOCALAPPDATA%\ApiCollabPlatform. Sensitive saved fields are protected with Windows user-scoped encryption. Use the app’s password-encrypted portable backup to move work between computers or Windows accounts.
Run either installer and choose your folder. Open API Workbench from the Start menu. Close the app before updating or switching editions. Both editions share one installation; uninstalling removes program files and shortcuts while preserving your local workspaces.
The desktop app plus apicollab.exe. Open API Workbench CLI from the Start menu, or run it from its installation folder. It lists local collection IDs and runs saved collections with environments, retries, delays, and stop-on-failure.
They are marked Coming soon. This beta focuses on Free Local. Cloud sync and shared team workspaces are unavailable in this release.
The installers are unsigned beta builds for evaluation. Existing dependency security advisories are documented in the bundled beta notes. Back up important local work before testing updates. The installers ship with no saved workspaces, credentials, or test history.
