Bruno

Bruno is a local-first API client designed for building, testing, and managing network requests across a wide range of protocols. By storing all collections and configurations as plain-text files directly on the local filesystem, it enables native version control and offline access, ensuring that project data remains under user control without requiring cloud synchronization.

The platform distinguishes itself through a declarative approach to API management, utilizing a domain-specific language to define request parameters and metadata. This architecture supports a robust testing environment where users can execute custom JavaScript-based validation scripts, perform complex assertions, and automate multi-step workflows. Its multi-protocol engine provides a unified interface for interacting with REST, GraphQL, gRPC, WebSocket, and SOAP services, while integrated environment-aware management allows for seamless switching between different deployment configurations.

Beyond core request execution, the tool includes a comprehensive suite of utilities for documentation generation, secure authentication, and CI/CD integration. It supports advanced security workflows through various credential management protocols and secret providers, while its command-line interface facilitates parallel execution and data-driven testing within automated pipelines. Users can also leverage AI-driven automation to generate collections and test scripts, further streamlining the development process.

Electric is a Postgres data synchronization engine and replication proxy designed to enable local-first software. It replicates data from Postgres databases to client-side stores in real time using logical replication, allowing applications to maintain a local embedded database for offline access and low-latency updates. The system distinguishes itself by using shapes to filter and authorize specific subsets of database rows and columns before streaming them to clients or edge workers. It further supports multi-user collaboration by integrating a conflict-free replicated data type framework t
