3 alternatives
Covers most of the same work, with trade-offs noted on each card.
Best for a terminal-first agent that works with many models
MIT-licensed and free. Model usage is billed by your provider, or through the optional paid Zen service. Free models are included. Free version: The agent is free and includes some free models. Zen and Go are optional paid model services. Other providers bill you directly.
Best for agent-style coding with your own model keys
Apache-2.0 and free, but you pay your model provider for usage unless you run local models. No inline completions, so keep a completion tool alongside it. Free version: The extension, desktop app and CLI are free. You pay your model provider, or use local models. Enterprise plans are paid.
Right for specific needs, or not yet mature enough to recommend widely.
Best for self-hosted completions on your own server
Development has slowed, with v0.32.0 in January 2026 as the last release. Models run on hardware you provide. Team and Enterprise plans are paid. Free version: The Community edition is free to self-host. Team and Enterprise plans add paid features and support.
