Vibe Coding with OpenCode
Terminal-first, open-source AI coding — for builders who live in the command line.
What is OpenCode?
OpenCode is an open-source terminal AI coding tool built for people who prefer the command line over GUIs. It connects to multiple AI providers (Claude, GPT, local models) and lets you code through conversation — right in your terminal.
It's lightweight and fast. No Electron app, no VS Code dependency, no subscription. Just a CLI tool that reads your project, understands your codebase, and helps you write code through natural language prompts. It supports file editing, code generation, and project-wide refactors.
Builders pick OpenCode when they want AI coding without the overhead. It's the minimalist's choice — powerful enough for real work, simple enough to not get in your way.
Why OpenCode + YepAPI?
Terminal-first
No GUI, no overhead. OpenCode runs in your terminal and stays out of your way.
Open-source
Free, transparent, community-built. No subscription, no vendor lock-in.
Multi-model
Use Claude, GPT-4, or local models. Pick the AI that fits your workflow and budget.
OpenCode is for builders who want AI coding without the bloat. Feed it YepAPI's docs and it understands every endpoint. Ask it to add a SERP tracking feature and it reads your project, writes the API calls, and edits the files — all from your terminal.
The open-source nature means you control everything. No telemetry you didn't opt into, no features gated behind a paywall. Combine it with YepAPI's pay-per-call pricing and you have a fully transparent, no-subscription stack for building API-powered tools.

Frequently asked questions
Both are terminal AI tools, but they have different philosophies. Aider focuses on git-aware pair programming with automatic commits. OpenCode is a more general-purpose terminal AI with broader model support. Both work great with YepAPI.
OpenCode itself is free and open-source. You provide your own AI model API key. YepAPI gives $5 free credit on signup. The only cost is the AI model usage, which you control by choosing your provider.
Yes. It reads your entire project, understands file structure, and can make multi-file edits. It's particularly good for CLI tools and backend scripts that integrate with APIs like YepAPI.
