An in-depth comparison of Kilo Code and OpenCode across output quality, autonomy, reliability, speed, value, and ease of use. Vote for your favorite.
Either way, you pay for the model calls. A median coding-agent day on our gateway is 95 requests and 8.6 million tokens. The table prices every step at one model’s rate.
Both run on Standard Compute, where each step goes to the cheapest model that can do it: routine steps go to efficient open models, hard ones to frontier models such as Claude Fable 5.1 or GPT-6 Astra.
| Model | Typical day | Busy day |
|---|---|---|
| Claude Opus 5.5 | $7.34 | $59.10 |
| Claude Sonnet 5.5 | $3.67 | $29.55 |
| GPT-6 Luna | $0.23 | $2.43 |
Fixed monthly plans from $19. Eligible new accounts can try $0.25 of compute first, no card. Trial terms

Kilo Code and OpenCode answer the same question ('open-source agent, any model, no lock-in') in two different rooms. Kilo Code is a VS Code extension: multi-file edits, refactoring, and context-aware generation appear where you already work, with the low setup friction of an editor marketplace install. It's the more approachable of the two, and its ease-of-use is its strongest score.
OpenCode is the terminal counterpart: a TUI agent with LSP integration and proper session management that works anywhere a shell works, including servers and SSH sessions where VS Code extensions aren't an option. It asks slightly more of you up front and gives back an agent that isn't tied to an editor window.
Both are free and open source, and both point at any OpenAI-compatible API, so the honest tiebreaker is simply where you want the agent to live.
Choose Kilo Code if you are vS Code users who want an open-source AI coding assistant. Choose OpenCode if you are terminal users who want a polished AI coding interface with LSP support.
In our editorial scoring, OpenCode leads in 2 of six categories (output quality and autonomy), while Kilo Code leads in 1 (ease of use). On price, Kilo Code runs free (free models or byo key) / kilo pass from $19/mo and is open source; OpenCode runs free (mit) / free zen models / go $10/mo and is open source.
Across 133 community votes on this matchup, Kilo Code currently leads in 6 of six categories. Cast your own vote above to move the needle.

Kilo Code is an open-source (MIT) coding agent that runs as a VS Code extension, a JetBrains plugin and Kilo CLI (a fork of OpenCode). It supports multi-file editing, refactoring and context-aware code generation. The tools are free: you can start on its free models without a card, bring your own key for any OpenAI-compatible API, or buy models through Kilo's gateway at provider rates, with the optional Kilo Pass from $19 a month adding bonus credits.
OpenCode is an open-source (MIT) AI coding agent best known for its terminal TUI, now also shipping a desktop app and IDE extensions with OpenCode 2. It connects to 75+ LLM providers through models.dev, has LSP integration for real code understanding, and runs several sessions in parallel. The tool is free; for models you bring your own key, use OpenCode's free Zen models, pay as you go on Zen, or subscribe to its Go plan ($10/month, Go Plus $40).
