What it is

Kilo is an open-source AI coding agent that runs inside VS Code, JetBrains, and the CLI, and connects to more than 500 AI models through one interface. It has a genuine $0/month free tier built on a rotating free model catalog plus bring-your-own-key routing for Mistral and Gemini, with paid Kilo Pass credits starting at $19/month once you need heavier or frontier-model usage.

What you get free vs paid

Verdict

Where it wins and loses

Pros

  • Access to 500+ models through Kilo Gateway with no markup over provider pricing
  • Genuine $0/month free tier: a rotating free model catalog plus BYOK routing for Mistral and Gemini
  • One agent shared across VS Code, JetBrains, CLI, and cloud, so context carries between surfaces
  • Fully open source, so you can see exactly what it sends and where

Cons

  • More setup than a single-vendor tool; getting the best results means actively picking models per task
  • Free-tier models trade off quality against frontier options, and a few providers log prompts on free plans
  • The feature set moves fast and still has rough edges in places

Worth it for developers who want control over which model touches their code and don't mind some setup; skip it if you just want one default that works without decisions.
