Chamber
Chamber is a local-first secrets manager for storing sensitive information in vault files on your system.
What Chamber is
Chamber is a local-first secrets manager for storing sensitive information in vault files on your system. It supports passwords, API keys, environment variables, SSH keys, certificates, database credentials, and notes. Vaults use SQLite with WAL mode, and the project specifies Argon2id key derivation and ChaCha20-Poly1305 encryption with 256-bit keys and 96-bit nonces. You can keep multiple independent vaults and switch between them. Chamber offers a command-line interface and an interactive terminal UI with search, filtering, and clipboard integration. Its backup tools include scheduling, configurable retention, compression, and integrity verification; data can be imported or exported in JSON, CSV, or Chamber Backup formats. A REST API provides secret and vault operations with JWT authentication and scoped authorization. The API listens on localhost by default, and HTTPS is recommended for production. Chamber is free and MIT-licensed, with Linux, macOS, Windows, and self-hosted availability. Exported backups contain plaintext and should be handled carefully.
