Best alternatives to Kilo Code in 2026

Most AI coding assistants lock you into one model provider and quietly add a margin on top of what that model actually costs to run. Kilo Code takes a different approach: it's a fully open-source coding agent, so you can see exactly what prompts and context it sends, and it lets you bring your own API keys or pay through its gateway at the same rate the model provider charges directly. Kilo Code works as a VS Code extension, JetBrains plugin (IntelliJ, PyCharm, WebStorm), CLI tool, and cloud agent, with specialized modes for writing/refactoring code, planning features (Architect Mode), fixing bugs (Debug Mode), and general Q&A (Ask Mode), plus automatic model routing between efficient, frontier, balanced or free strategies depending on the task. It's MIT-licensed with visible prompts and context windows — a meaningful transparency claim in a category where most tools are closed-source black boxes. The company reports 3 million-plus users and over 40 trillion tokens processed, with customers at Meta, Amazon, Airbnb, PayPal, Square and Red Hat, and was recently acquired by Anaconda. Pricing is free to start, Teams at $15/user/month, and custom Enterprise; AI inference runs either pay-as-you-go through the Kilo Gateway at provider rates or via Kilo Pass subscriptions starting at $19/month with bonus credits, while cloud compute (running agents in Kilo's infrastructure) is billed per second, from roughly $0.33 to $1.20/hour depending on the task.
