Happier is an open-source, end-to-end encrypted companion app for AI coding agents: Claude Code, Codex, OpenCode, Cursor, Pi, Grok, Gemini, Copilot, Qwen, Kimi, Kilo, Kiro, Auggie. Run sessions on your computer, and continue them from your phone. Use our desktop app or web app, and truly start working from anywhere. YOUR EXISTING SESSIONS? ALREADY THERE. Open any Claude Code, Codex or OpenCode session running on your computer — live, from your phone. Nothing to migrate, nothing to learn. APPROVE FROM ANYWHERE Your agent asks to run a command and you get a push notification with Allow and Deny on it. Sessions waiting on a decision rise to a "Needs attention" group at the top of your list; everything still running gathers under "Working". REVIEW THE DIFF. SEND NOTES TO YOUR AGENTS. Browse every line your agent changed. Mark the exact lines you want addressed, choose which notes to send, and hand them straight back — same session, or a new one. EDITOR. GIT. TERMINAL. ONE TAP AWAY. Chat, files, Git and a live terminal, each its own tab. Open a file to read or edit it, review the diff, manage branches and open a pull request. YOU LOVE THE TERMINAL? WE DO TOO. If you want, you can keep running Claude Code, Codex or OpenCode in their native TUI. Happier mirrors them to every device, so you can follow along, send messages and approve permissions from anywhere — and switch between the terminal and Happier whenever you like. A COLLEAGUE YOU CAN TALK TO The voice assistant watches every running session. Brainstorm the next change, approve a permission or send a message, without picking up the phone. YOUR SESSIONS WORK AS A TEAM A session can start another session, send it messages and read its transcript — so a Claude session and a Codex session can split the work between them. Each one still runs its own subagents, on whichever backend you choose. USE THE SUBSCRIPTIONS YOU ALREADY PAY FOR Happier reuses the subscriptions and logins your existing CLIs already use — Claude, Codex, Cursor, Gemini, OpenCode. No new bill, no double billing, and Happier sells no AI of its own. POOL YOUR ACCOUNTS. KEEP THE SESSION GOING. Link accounts you own into a pool and watch usage and quota resets for every one of them in the app. Nothing switches until you build a pool — once you have, Claude Code and Codex sessions can change account without stopping, moving to whichever member has the most quota left, at most once a turn and never past a reset time the provider has published. OPEN SOURCE. END-TO-END ENCRYPTED. Your messages, prompts and session content are encrypted on your device before they reach a server: AES-256-GCM under a key drawn for that one session, sealed to an account key that is created on a device and never leaves your devices. The relay stores ciphertext and has nothing to open it with. Put the relay on your own hardware with one command — happier relay host install — or reach your computer over Tailscale and use no relay at all. FREE, AND MIT LICENSED The CLI, the mobile apps, the desktop app, the web app and the relay. No seat count, no trial, no feature gate. github.com/happier-dev/happier HOW TO START 1. On your computer: curl -fsSL https://happier.dev/install | bash (Windows: iwr https://happier.dev/install.ps1 -useb | iex) 2. Scan the QR code your terminal prints, with this app. 3. Start a session from the app, or run "happier claude" or "happier codex" in your terminal. REQUIRES A COMPUTER Happier is the client for agents running somewhere you control. It does not run an agent in the cloud, and your repository is never copied to us: the agent reads and writes files on the computer it runs on, and that computer stays the only full copy. Not affiliated with, or endorsed by, Anthropic, Google, GitHub or Cursor. ## Key features - Collaborative coding sessions - Support for multiple AI providers - Persistent and resumable sessions - Seamless switching between devices - End-to-end encryption - Infinite message history ## Chart rankings - #201 in Top Free · Developer Tools (US App Store) ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/happier-remote-claude-codex/id6758554297/reviews.md ### 5/5 — Great for terminal work *2026-07-31* Very well done ### 4/5 — where is 0.2.0/0.2.1？ *2026-05-09* i found it on github release but here is still 0.1.2 **Developer response:** Thank you for the review! We have multiple releases channels and the app version does not always equal the CLI version, which is why they can be different. Version 0.2.6 will be out soon, looking forward to your feedback! ### 5/5 — 做的非常棒 *2026-03-17* 现在有一些小问题，例如新增会话选择项目路径时有bug **Developer response:** Thank you very much for your review!

It aims for faster iteration and greater reliability compared to some other tools. ## Version history (last 3 releases) ### 0.2.10 — 2026-08-20 Every session now carries files, git, diffs and a real terminal, you can pool your subscriptions together, and Cursor and Grok join the party. EDITOR, GIT, TERMINAL - YOUR NEW COCKPIT Six tabs — Chat, Files, Git, Navigation, Tabs and Terminal — and you can send from any of them without leaving what you were doing. POOL AND LOAD-BALANCE YOUR SUBSCRIPTIONS Connected Services links the Claude and Codex accounts you own to Happier, so you can use them on any of your machines and watch quota and reset times in the app. Pool several and a session moves to whichever member has the most left, within the switch limits you set. IMPROVED PENDING QUEUE Queue a prompt while an agent is busy or steer it. Drag pending messages to reorder them, or push one to the front. CLAUDE UNIFIED MODE Run the real Claude Code TUI in a terminal you can drive from your phone or from your desk, fully managed by Happier. Use the full power of Happier UI from your phone, while still being able to work in the Claude terminal at the same time. No more switching! Turn it on in Claude settings. REVIEW AND SHIP Comment on individual lines of a diff, gather notes across files, then send the whole review back to the session. Push a branch and open a pull request without a laptop. CURSOR & GROK Cursor and Grok are fully supported, bringing it to 13: Claude Code, Codex, Cursor, Grok, OpenCode, Gemini, Copilot, Qwen, Kimi, Auggie, Kilo, Kiro and Pi. Claude Opus 5 and two MiniMax profiles are selectable. STAY ORGANIZED Folders, tags and pins sync across your devices. Long-press to select several sessions, then archive, move or mark them read together. IMPROVED TRANSCRIPT Long replies no longer drag you back to the bottom while you are reading. Older messages load in place. Your reading position survives a reload. Pin messages and jump straight to them, even past what is loaded. ALSO Mermaid diagrams render on iOS. Generated images appear inline. Thirty-five measured performance improvements and over 150 fixes. Happier is free and MIT-licensed. Tell us what is broken: github.com/happier-dev/happier ### 0.1.2 — 2026-04-05 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.
