What is OpenCode?
OpenCode helps developers understand a project, write code, and make changes to it. It also lets them run development commands, export a session, and resume that session.
According to its documentation, OpenCode lets you:
- explain how a project works
- write and edit code
- run development commands
- export and resume a session
We file it under AI coding assistants, the category of tools to write and fix code, and it also overlaps with aI agent builders. The category lists 31 verified tools on this site.
The publisher is Anomaly Innovations, Inc., based in United States.
Who is it for?
It is mostly useful to these profiles: developers. The need it covers is simple to state: write and fix code.
OpenCode is a good candidate if:
- you want to try before paying
- you plan to connect it to your tools or automations through its API
- you want to read the code or host it yourself
Before deciding, run a trial on a real task and measure the time saved: it is the only criterion that really counts.
How much does OpenCode cost?
Pricing model: open source (public code). A free plan is offered, usually limited in volume or features.
The first paid plan costs $10 per month (OpenCode Go, optional model subscription; the software can be used for free), according to the pricing page, checked on October 24, 2026.
Per month, that is cheaper than the category median ($15 per month, based on tools with a published price).
To estimate what the same work would cost done directly with an AI model, use our API price calculator. Prices change often: always check the official site before subscribing.
Data and privacy
The publisher does not clearly state where data is hosted. Assume your content may leave your region.
For professional use, check that a data processing agreement (DPA) is offered, and do not send customers' personal data or confidential documents without one.
Exporting your content: JSON des sessions. Being able to get your data back makes switching tools easier later.
Three habits apply to every AI tool:
- turn off the use of your content for training if the option exists
- use a work account separate from your personal account
- review everything the tool produces before publishing or sending it
Platforms, languages and API
OpenCode runs on: web browser, Windows, macOS, Linux, and API.
Interface languages: English.
A public API lets you call it from your own programs or an automation tool, and plug it into an AI agent.
The source code is public: anomalycoanomalyco/opencode.
How we scored it
