RESTLab

RESTLab is a local-first API development workbench built for developers who want powerful API tooling without cloud dependencies, mandatory accounts, or unnecessary complexity.

Unlike many modern API clients, RESTLab stores everything directly inside your project. Collections, environments, request history, and OpenAPI integrations are saved as human-readable JSON files, making them easy to version, share through Git, and maintain alongside your codebase.

The application provides a complete workflow for working with REST APIs, including request management, environment variables, authentication, response inspection, code snippet generation, and OpenAPI-powered project integration. Developers can import existing OpenAPI specifications, automatically generate collections and requests, and keep them synchronized as their backend evolves.

RESTLab was designed with a strong focus on desktop productivity. Features such as multi-tab request editing, keyboard shortcuts, drag-and-drop organization, project history, and an integrated command palette help streamline daily development workflows.

Key Features:

1. Local-first architecture
2. No accounts, cloud services, or telemetry
3. Project-based JSON storage
4. OpenAPI import and synchronization
5. Environment management and variable resolution
6. Request history and response inspection
7. Multi-tab editing workflow
8. Code snippet generation for multiple languages
9. cURL import and export
10. Modern desktop-focused interface

RESTLab is currently under active development and serves as a demonstration of our approach to developer tooling: fast, transparent, project-centric, and fully under the developer's control.
