What is Evident?

Run powerful AI agents on your own machine. Reach them from Slack.

Evident makes a coding agent that runs on your machine — where your code, secrets, and tools already live — reachable from anywhere. You chat with it from the web, or @mention it from Slack like a teammate. Your code never leaves your environment; only the messages you send travel through Evident.

Under the hood, Evident is a thin control plane in front of a standard opencode serve running locally. The Evident CLI starts (or attaches to) OpenCode on your machine and connects it to Evident, which routes messages to it from the web and from channels like Slack.

What you get

• Your environment, not someone else's compute. The agent runs locally, so it has your repositories, your VPN access, your installed tools, and your credentials — without uploading any of it.
• A real chat from the web. Open your agent's chat and talk to it; messages stream back in real time, and questions or approvals are handled right there in the chat.
• Reach it from Slack. Once a developer connects Slack, the whole team can message the agent in a channel or thread — no setup on their side.
• Team-scoped by default. Everything you create belongs to your team, so teammates collaborate on the same agents.

Who it's for

Evident is for developers and small engineering teams who run (or are happy to run) OpenCode locally and want their coding agent reachable from Slack and the web — without putting their code on third-party compute.

Once a developer has set it up, non-technical teammates (PMs, support, ops) can use the agent entirely through Slack, with zero setup of their own.

The mental model

There's one idea to hold onto:

your machine  ⇄  Evident  ⇄  web & Slack

Your agent runs on your machine. Evident sits in the middle and makes it reachable. You and your team reach it from the web and from Slack. Local mode is the only runtime — there is no cloud runner to configure.

Where to go next

• Core concepts — the vocabulary Evident uses (agent, runner, conversation, channel, agent key, team).
• Quickstart — go from zero to a working agent you can chat with, in about five minutes.
• Local runner — how the agent runs on your machine in depth.
• Slack integration — bring your agent into your team's channels.
