Description

Happier: Claude Codex OpenCode
**Happier** is an open-source, end-to-end encrypted companion app for AI coding agents. It takes the power of Claude Code, Codex, Gemini, and OpenCode and lets you run sessions on your computer, and continue them from your phone — including collaboration, reliable resume, and full history access.

Whether you’re on a train through the Alps or grabbing a coffee, Happier ensures your AI coding sessions never skip a beat.

**Important**: This app requires the Happier CLI and at least one supported provider (Claude Code, Codex, Gemini, OpenCode) installed on your computer. The iOS app acts as a secure bridge between your local development environment and your mobile device.

### Why "Happier"?
Happier started as a fork of **Happy**. We were using Happy daily for work and loved the concept, but we needed faster iteration, stronger reliability, and a set of features that weren’t available yet. After weeks of building and refining, we are sharing it so others can try it and help shape what comes next.

Happier lets you **build** anything you want—with friends. We’ve rebuilt the foundation to support more models, more platforms, and more ways to work together.

### Features:
* **Collaborative sessions:** share a session with teammates & friends (private or public links).
* **Broad provider support:** works with Claude Code, Codex, Gemini, OpenCode, and more (configurable).
* **Persistent sessions:** resume sessions even after restarts; archive and return later.
* **Seamless switching:** move between terminal, web UI, and mobile while keeping context.
* **Subscriptions or API keys:** use your existing Claude Pro/Codex/Gemini subscriptions, or configure API keys in-app.
* **Infinite history:** scroll back through older messages in long sessions.
* **Pending queue:** edit/reorder queued messages before the agent processes them.
* **tmux support:** resume remote-started sessions locally (Claude).

### Security & privacy
* **End-to-End Encryption**: built using the same encryption as Signal (TweetNaCl)
* **Zero-Knowledge**: your code is encrypted on your machine before it ever hits the wire. We cannot read your data. Your encryption keys never leave your devices.
* **Built in Switzerland:** developed in Switzerland, with a strong focus on data protection and developer transparency.

### How It Works:
1. Install the `happier-cli` on your Mac, Linux, or PC.
2. Pair your device instantly with a secure QR code.
3. Start a session (e.g., `happier claude` or `happier codex`).
4. Code solo, or invite a friend to jump into the session with you.

### Community-Driven

**Happier** is completely open-source. We built this because we wanted a more powerful, more social way to interact with AI agents - and we want to build it in the open, shaped by the people who actually use it.

This project exists because we needed it ourselves - and we want it to evolve through real feedback. We aim to keep the community welcoming and contributor-friendly, whether you’re signaling an issue or proposing a larger idea.

What that means in practice:
* **Open development** and transparent discussions
* **Fast feedback loops** on issues and pull requests
* A focus on **solving real developer pain**, not chasing hype

If something feels broken, missing, or awkward - we want to hear about it.
Happier grows through shared experience and collaboration.

**Code faster. Code together. Be Happier.**

What's new

  • Version: 0.1.2
  • Last Updated:
  • This release is a major upgrade to self-hosting and cross-device workflows (plaintext mode, keyless auth, mTLS, "Add Phone" pairing, and safer canonical URLs), plus a big step forward in in-app development features (panes, files/source control, diffs, replay/forking, and OpenCode deeper integration). It also improves reliability across web/desktop/mobile with better crash recovery, diagnostics, notifications controls, and more resilient daemon connectivity.

    - Refactored the Files and Source Control UI to support richer session file workflows (changed-files review, repository tree, commit controls, files editing, and safer SCM operations like discard/stage).
    - Added directory filtering and viewability tuning helpers for SCM review surfaces.
    - Improved SCM reliability with adaptive polling, mutation invalidation, and better fallbacks when session/workspace paths are missing or a session is inactive.
    - Improved diff caching and prefetch behavior so loaded diffs are retained more reliably while scrolling and expanding rows.

    - Added a new pane-based UI architecture (details/right panes) with lazy loading, prefetching, and route integration for smoother navigation.
    - Added multi-pane appearance preferences and improved details tab open/pin behavior.
    - Added a resizable permanent sidebar drawer with persisted width preferences.
    - Improved connection status UI to show the active server label more clearly.

    - Refactored the code diff/rendering stack (Pierre web diff viewer, worker runtime/warmup, virtualization controls, unified folding, and improved syntax/language handling).
    - Improved markdown rendering for developer workflows with diff-aware code fences and better table scrolling.
    - Fixed a security issue by preventing Mermaid WebView HTML injection.

    - Improved transcript UX with tool-call grouping controls and timeline improvements.
    - Added compact/collapsible tool card behaviors and richer tool header/status handling (including clearer permission states).
    - Added support for freeform “Ask a question” prompts in tool renderers.
    - Improved list performance and stability by expanding FlashList usage, with a web fallback to FlatList on known FlashList layout crash signatures.

    - Added session fork actions in the UI (from header/info/actions).
    - Added “fork from message” semantics so forks happen at the expected point in the conversation.
    - Added Happier Replay forking support across providers, including replay-seed propagation for continue/fork workflows.
    - Added replay seed sizing limits to prevent oversized prompts and improve reliability.
    - Improved replay synopsis retrieval with synopsis pointers and bounded fallback scanning for faster recovery.
    - Added replay summary runner configuration support (backend/model), and ensured fork/continue flows forward summary runner settings when needed.

    - Implemented major OpenCode runtime/server integration (managed server orchestration, session control, question/prompt handling, and forking support).
    - Improved OpenCode runtime stability with readiness/health polling, safer shutdown cleanup, and better fallbacks when idle streaming is missing.

    - Added support for session pinning
    - Added support for session tags

    - Improved permissions display UI
    - Improved permissions notifications & user actions notifications

    - Added plaintext storage mode support for self-hosted servers (so sessions can be stored plaintext-at-rest when configured).
    - Added keyless external authentication support for self-hosted and enterprise auth providers.
    - Added mTLS login support for environments that require certificate-based authentication.
    - Added an “Add your phone” pairing flow, including QR-based pairing from web/desktop and in-app pairing helpers.
    - Added QR restore flows so reconnecting a device is smoother when migrating or recovering access.

    And many more! Full changelog on GitHub
