# Tool Highlight: OpenCode — the Free, Model-Agnostic Coding Agent You Can Self-Host

> What OpenCode is, who it's for, how to start in one command, what it costs (as of July 2026), and the honest catch — the terminal coding agent that refuses to lock you to a single model vendor, now at ~7.5M developers.

## Key takeaways

- A free, MIT-licensed, terminal-first AI coding agent from Anomaly (the team formerly known as SST) whose defining choice is that it doesn't own the model.
- For founders and small teams who want a capable coding agent without being tied to one vendor's pricing or uptime — you bring your own key and point it at any of 75+ providers, or a model you self-host.
- Install is one command (curl … | bash, or npm/Homebrew/Scoop); it runs in your terminal with two built-in agents — 'build' (full access) and 'plan' (read-only) — plus LSP integration for 20+ languages and MCP support to connect GitHub, Postgres, Slack, and custom tools.
- It's free and open source (MIT), self-hostable and even air-gappable for regulated work; as of July 2026 it's at ~184K GitHub stars, ~7.5M monthly developers, and v1.17.18 (July 9).
- The catch: model-agnostic means you supply — and pay for — the model tokens yourself; it's terminal-first (great for engineers, less so for non-technical founders); and 'bring your own everything' means a little more setup than a fully hosted, single-vendor tool.

## At a glance

| Dimension | OpenCode | A single-vendor hosted agent |
| --- | --- | --- |
| Model choice | 75+ providers, bring your own key | Locked to that vendor's models |
| License | MIT, open source | Proprietary |
| Where it runs | Your terminal, self-hostable, air-gappable | Their cloud |
| Cost shape | Free tool; you pay model tokens | Bundled subscription |
| Best for | Engineers who want control and portability | Teams who want zero setup |
| Lock-in risk | Low — swap models freely | High — pricing/uptime is theirs |

## By the numbers

- **184K** — GitHub stars (as of July 2026)
- **~7.5M** — monthly developers using it
- **75+** — model providers it can connect to (bring your own key)
- **2** — built-in agents — 'build' (full access) and 'plan' (read-only)
- **20+** — languages with LSP integration for real compiler feedback
- **v1.17.18** — latest release, July 9, 2026
- **MIT** — license — inspect, modify, self-host

There's a quiet decision buried in every AI coding tool: *who owns your workflow?* Most of the popular ones answer "we do" — the agent and the model ship together, so your day-to-day depends on one company's pricing, uptime, and roadmap. OpenCode answers differently, and this month that answer reached scale: it crossed roughly **7.5 million monthly developers** and **184K GitHub stars**, shipping **v1.17.18** on July 9. For founders, the interesting thing isn't the star count — it's the design choice underneath it.
**What it is:** [OpenCode](https://opencode.ai/) is a free, **MIT-licensed**, terminal-first AI [coding agent](/topics/coding-agents) from **Anomaly** (the team formerly known as SST). Its defining feature is that it *doesn't own the model*: you bring your own key and point it at any of **75+ providers**, or at a model you self-host.
What it is
OpenCode runs in your terminal and gives you two built-in agents: a **build** agent with full access to read and change your code, and a **plan** agent that's read-only, for analysis you don't want touching files. You switch between them with a keystroke. Under the hood it wires into your project the way an engineer expects: **LSP integration for 20+ languages** (so the model gets real compiler diagnostics, not guesses), and **MCP support** to connect GitHub, Postgres, Slack, and any custom tool you expose.
The load-bearing difference from most coding agents is the model relationship. OpenCode is **model-agnostic by design** — 75+ providers, your own keys — and because it's MIT and self-hostable, you can run it locally or even **air-gapped**, which is the difference between "maybe someday, for regulated teams" and "today." (We put it side-by-side with the incumbent in [OpenCode vs. Claude Code](/posts/opencode-vs-claude-code); this piece is about the tool on its own terms.)
Who it's for
If you're an engineer or a technical founder who wants a capable agent **with control** — pick the best or cheapest model today, switch tomorrow, keep your source on your own machine — this is squarely aimed at you. It's also the right call for anyone with a compliance reason to keep code off third-party clouds: self-hosting and air-gapping are first-class, not an afterthought.
Who it isn't for: a **non-technical founder** who wants to click around a codebase from a friendly web UI. OpenCode is terminal-first, and its power lives in the TUI, the MCP connections, and the LSP feedback loop — none of which land if you're not comfortable in a shell. For that reader, a hosted point-and-click tool is a better fit, at the cost of the portability OpenCode is built around.
How to start
One command:
```
curl -fsSL https://opencode.ai/install | bash
# or: npm i -g opencode-ai@latest   (Homebrew and Scoop also work)
```
Then set an API key for whatever provider you want — a frontier hosted model, a many-models router, or a model you [self-host on your own hardware](/posts/portable-llm-stack-providers-and-chips) — and run `opencode` inside your project. You'll drop into the TUI with the build/plan agents ready. Because it speaks to 75+ providers, the same install works whether you're on a [frontier model](/topics/model-selection) this week and a cheaper one next.
What it costs
The tool is **free and open source**. The only thing you pay for is the **model** — OpenCode is bring-your-own-key, so your cost is whatever your chosen provider charges for tokens. Versus a bundled single-vendor subscription, that's the trade: you manage the model bill yourself, and in exchange nothing about your workflow is tied to one company's pricing. If you already hold provider credits, running OpenCode is effectively free.
The honest catch
Three of them. **You supply and pay for the model** — there's no bundled model, which is the entire point but also a setup step. It's **terminal-first**, so the value doesn't reach a non-technical user. And **"bring your own everything"** is a little more configuration than a fully hosted tool — the reward being exactly the thing the [run-anywhere week](/posts/run-anywhere-inference-week-july-2026) is about: a core dev workflow that no single vendor can reprice out from under you.
> The star count is a proxy. The real signal is 7.5M developers voting that their coding agent shouldn't come welded to one model company.

## FAQ

### What is OpenCode, in one line?

A free, open-source (MIT) AI coding agent that runs in your terminal and connects to 75+ model providers with your own API keys, built by Anomaly (the team formerly known as SST). Its whole design premise is that you shouldn't be locked to one model vendor to write code.

### Who is it for, and who is it not for?

It's for engineers and technical founders who want a capable coding agent with control and portability — pick the best or cheapest model today, switch tomorrow, and keep your source on your own machine (it's self-hostable and can run air-gapped, which matters for regulated work). It's less suited to a non-technical founder who wants to poke at a codebase from a friendly UI: OpenCode is terminal-first, so it rewards people comfortable in a shell.

### How do I start?

One command: `curl -fsSL https://opencode.ai/install | bash` (or `npm i -g opencode-ai@latest`, Homebrew, or Scoop). Then set an API key for whatever provider you want — a frontier hosted model, a router, or a model you self-host — and run `opencode` in your project directory. You'll get a terminal UI with a 'build' agent (full access to make changes) and a 'plan' agent (read-only, for analysis you don't want touching files), switchable with a keystroke.

### What does it actually cost?

The tool is free and open source. What you pay for is the model: OpenCode is 'bring your own key,' so your only cost is the tokens your chosen provider charges. That's the trade — versus a bundled single-vendor subscription, you get portability and often lower cost, but you manage the model bill yourself. If you already have provider credits, it's effectively free to run.

### What's the honest catch?

Three things. First, model-agnostic means you supply and pay for the model — there's no bundled model, which is the point but also a setup step. Second, it's terminal-first; the power is in the TUI, MCP connections (GitHub, Postgres, Slack, custom tools), and LSP feedback, none of which land for someone who wants a point-and-click app. Third, 'bring your own everything' is a little more configuration than a fully hosted tool — the reward is that nothing about your workflow is hostage to one company's pricing or uptime.
