The project emphasizes self-improvement, self-healing behavior, multi-provider operation, and deployment as a terminal UI, CLI, or daemon. The repository’s release history and changelog show rapid iteration, with configuration, channels, profiles, browser automation, memory, and service-management capabilities consolidated into the same executable. ### Adoption history OpenCrabs is distributed as release binaries, a Cargo package, source code, and Homebrew packaging. Its official repository documents Linux, macOS, and Windows operation, plus optional always-running daemon services. Adoption is still early-stage, but the project exposes a broad integration surface including terminal tools, browser automation, scheduled tasks, provider switching, profiles, and messaging channels. ### How it is used The first-run wizard configures a provider and workspace. Users can run interactive sessions, execute slash commands, create isolated profiles, or install the daemon as a user service. The default profile uses ~/.opencrabs. Non-secret settings reside in config.toml, commands.toml, and tools.toml; API keys and channel tokens reside in keys.toml with restrictive file permissions. Named profiles keep isolated copies beneath ~/.opencrabs/profiles//. ### Why package nerds care OpenCrabs is notable as a single Rust binary that packages an agent runtime, terminal interface, daemon, provider registry, tools, memory, scheduling, and channel integrations. Its profile-aware configuration resembles a conventional Unix CLI while supporting a comparatively large application surface. Its explicit separation of non-secret configuration from keys.toml is useful to package maintainers and operators because it gives configuration and credentials distinct lifecycle and permission expectations. ### Timeline - Early project: OpenCrabs emerged as a Rust-based autonomous terminal agent. - 2026: The official repository shows rapid release activity and expanding profile, daemon, channel, browser, and tool support. ### Related projects - Related technologies include Rust, Cargo, Ratatui, SQLite, Claude Code, GitHub Copilot, MCP, the A2A protocol, Chromium CDP, and supported LLM-provider APIs. ### Sources - ## Security Notes No matching local secret-handling manifest was found for opencrabs. Package metadata is still published here so future coverage has a stable package URL. ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials. Automic Vault can use them as review targets for secret scanning, migration, and command approval. ## Configuration files - Unix: ~/.opencrabs/config.toml, ~/.opencrabs/commands.toml, ~/.opencrabs/tools.toml, ~/.config/opencrabs/config.toml, ./opencrabs.toml ## Credential files - Unix: ~/.opencrabs/keys.toml ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** opencrabs - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Related links - [AI and agent packages](https://pkg.so/ai-agent-tools/) - Matched AI model, agent, coding-agent, orchestration, or MCP metadata. - [Language runtime packages](https://pkg.so/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [Networking and protocol packages](https://pkg.so/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [rtk](https://pkg.so/brew/rtk/) - Runtime dependency declared by Homebrew. - [pkgconf](https://pkg.so/brew/pkgconf/) - Build dependency declared by Homebrew. - [cmake](https://pkg.so/brew/cmake/) - Build dependency declared by Homebrew. - [llvm](https://pkg.so/brew/llvm/) - Build dependency declared by Homebrew. - [rust](https://pkg.so/brew/rust/) - Build dependency declared by Homebrew. - [hermes-agent](https://pkg.so/brew/hermes-agent/) - Local package facts share a topical domain.
