Summary

Tessera organizes and manages parallel AI coding sessions across projects, collections, and Git worktrees. It allows developers to run multiple AI agents (Claude Code, Codex, OpenCode) side-by-side, tracking sessions, files, branches, and pull requests to streamline complex AI-assisted development workflows.

How It Works

Tessera uses a local runtime with a provider-based CLI layer, abstracting AI agent interactions via a CliProvider contract. This architecture isolates CLIs and normalizes diverse protocols (Claude Code, Codex, OpenCode) into a unified realtime message model. The core agent workspace model treats chats, tasks, Git worktrees, and PR states as first-class entities, enabling seamless, provider-agnostic multi-agent development management.

Quick Start & Requirements

Installation options include a desktop app (Windows, macOS, Linux beta) from GitHub Releases, a browser runtime via npm install -g @horang-labs/tessera (requires Node.js 20+, npm 10+), or Docker Compose. All methods require authenticated provider CLIs (e.g., claude login). Windows desktop builds are unsigned. Official GitHub Issues (https://github.com/horang-labs/tessera/issues) and Discussions (https://github.com/horang-labs/tessera/discussions) are available for support.

Limitations & Caveats

Windows desktop builds are unsigned, potentially triggering security warnings. Linux support is in beta. Team and enterprise features are under active development and not yet generally available. Tessera relies on external, user-installed and authenticated AI provider CLIs.
