Happier vs Lotse

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.

Lotse is a coding agent for your GitHub repositories. Describe a change on your phone, and Lotse works on it in the cloud, runs your tests and opens a pull request for you to review, even when the app is closed. You get a push when it's ready. HOW IT WORKS 1. Sign in and connect GitHub. The GitHub App "Lotse Agent" can only see the repositories you select. 2. Pick a repo and describe the change: a bug fix, a missing test, a small feature. 3. Close the app if you like. The task runs in the cloud; small changes usually take a few minutes. 4. Review the pull request on GitHub. It shows the test result honestly, also when tests fail. Merge it or send it back. WHAT YOU GET - Pull requests on your own repos. Nothing is merged without you. - Tests run for JavaScript/TypeScript, Python, Go, Rust, Java/Kotlin and Flutter/Dart, including monorepos. - A live log of what the agent is doing. - A push notification when a task is finished. - You decide which repositories Lotse can access, and you can remove access on GitHub at any time. Lotse works best on small, well-defined changes: fixes, tests, small features. Repositories that need a database or a browser to test, and Android, Ruby, PHP or .NET projects, are limited. Lotse says so in the pull request. FREE AND PRO Try it free while capacity lasts. Lotse Pro raises the limits, removes ads and gives you more AI prompt improvements. Task limits are per day and reset every day. AI AND YOUR DATA Before your first task the app asks for your consent: your task description and the repository code are sent to AI model providers via OpenRouter to do the work. AI output can be wrong, so always review a pull request before you merge it. You can delete your account in the app. Privacy policy: [PRIVACY URL] SUBSCRIPTION Lotse Pro is an auto-renewing subscription (monthly or yearly), billed through Google Play or your Apple ID. It renews unless you cancel at least 24 hours before the period ends. Cancel any time in your store's subscription settings. Terms of use: [TERMS URL] Formerly Jules Console. Google ends Jules on December 31, 2026; if you used Jules in this app, your sessions stay viewable until then.
