| Open source | No | Yes (Apache 2.0) |
| Pricing | Hobby (free): 2k completions/month, 50 slow requests/month. Pro $20/month. Pro+ $60. Ultra $200. Teams $40/user/month. June 2025 pricing pivot reduced effective fast requests by ~55%. | Pro $20/month base + usage-based credits ($20/mo of frontier model included). Pro+ $60/month (3× usage). Ultra $200/month (20× usage). No free tier. Rolling 5-hour credit limits frustrate heavy users. |
| Best for | Builders who want an IDE-first AI experience and the ability to switch between Claude, GPT, and Gemini mid-session.
