Every AI coding agent Happier runs

Happier installs on the computer that holds your repository, starts the vendor’s own CLI there as an ordinary subprocess under your own login, and carries the conversation to your other devices end-to-end encrypted. It hosts none of these agents, and puts no model of its own in front of them.

What that means in practice is that you keep every agent you already pay for and stop needing a different remote for each one. Each page below covers one agent in the detail you want before installing something: the command Happier runs and what it hands that binary, how a permission choice made on a phone is expressed to that particular CLI, which sign-in flow the app can start for you, how the binary gets onto your computer, whether the session can move to the agent’s own terminal interface, and the questions people ask about running it this way.

Per-agent limits — which sessions can be forked, resumed, reattached or moved to another computer — live in the Happier documentation rather than here, because the documentation ships with the product and a marketing page does not.

The release ships one more id than this page has cards for. Here it is, with the reason it has no page of its own.

customAcp

Custom ACP is not a vendor integration, it is the door for the ones we have not built: any CLI that speaks the Agent Client Protocol can be added as a backend of your own. There is no page because what it can do is whatever your CLI implements, and a page about that would be a page about your code. The Happier docs cover the configuration.

Four more are defined and on the way. None of them is in the build you can install today, and none is counted in the 13 above.

Antigravity CLIGoogle · agyComing in v0.3

Google’s Antigravity CLI is coming in the next version — a terminal-hosted backend that will run on a Gemini credential. It is not in the build you can install today.

oh-my-pi CLIcan1357 · ompComing in v0.3

oh-my-pi is a separate CLI from Pi, with its own binary and its own release repository. It arrives in the next version as an agent in its own right. Until that ships, the Pi page is about the pi binary, and nothing on this site runs omp.

CodeRabbitCodeRabbit · coderabbitComing in v0.3

CodeRabbit is a review tool rather than a conversational coding agent, so even when it lands there is no session to open on your phone — it would be a tool run inside one.

DeepSecDeepSec · deepsecComing in v0.3

DeepSec is a security-scanning tool run, on the same footing as CodeRabbit: no conversation, no session to carry between your devices. Named here for completeness, not as something you can use.

When one of them ships in v0.3 it moves up into the grid and gets a page of its own.

Anything speaking the Agent Client Protocol can be added as a backend of your own without waiting for us. That path has no page here because what it can do is whatever your CLI implements, and writing a page about it would be writing a page about your code.

Install Happier on the computer that holds your code, then start any agent on this page by name — happier claude, happier codex, happier opencode. The agent runs there, under your own subscription or API key. Happier is the transport and the interface, not a middleman for the model call.
