One AI Coding Tool to Rule Them All
OpenCode just became the most-used open-source AI coding agent on the planet — and it works with any AI model you already pay for.
What is this, exactly?
Imagine you hire a contractor to renovate your office. Most AI coding tools are like hiring through an agency that locks you in: you pay their rates, use their process, and if you leave, you start over. OpenCode is more like hiring the contractor directly — you choose who you work with, and you keep full control.
OpenCode is an AI assistant built specifically for writing and editing code. It just hit 7.5 million developers using it every month, which put it ahead of Cursor and Windsurf in LogRocket's latest rankings. And it did this by doing something simple: it works with over 75 different AI models — Claude, GPT, Gemini, or even a model running entirely on your own computer.
Why does this matter to you?
Right now, tools like Claude Code or GitHub Copilot charge per seat, per month, per person on your team. OpenCode flips that. You bring your own API key — meaning you pay your AI provider directly, at cost — and OpenCode itself is free. For a studio with five developers, that difference adds up fast.
It also stores nothing about your code or your business. That matters if you work in healthcare, finance, or anywhere with client confidentiality requirements.
What should you take away from this?
If you're paying a per-seat subscription for your team's AI coding tool, it's worth asking your developer: could we switch to something where we only pay for what we actually use? That one question might save you a few hundred euros a month.
Words worth knowing
API key — A private password that lets a piece of software talk to an AI service on your behalf. You pay for what you use, like a utility bill.
Open-source — Software whose inner workings are public and free to inspect or modify. Think of it as a recipe anyone can read.
Model-agnostic — A tool that doesn't care which AI brain it uses. Swap Claude for GPT tomorrow and nothing breaks.
Vendor lock-in — When switching away from a tool is so painful (data, cost, habit) that you feel stuck with it even if you're unhappy.
