Questions
- Is FreeFlow a free alternative to Cline?
- Yes. FreeFlow costs nothing: three models have no usage cap, and you get $50 of credit every week for frontier models like Opus 5.5 and GPT 6.1 Sol. A small sponsor card in the app pays for the tokens.
- Can I use FreeFlow and Cline together?
- Yes. FreeFlow works on your project folder in its own window, so you can keep using Cline or any editor while the FreeFlow agent makes changes.
- What's the catch?
- The Harness shows ads, and model requests only run inside the Harness, not through your own scripts. Ads are chosen without your personal data and never appear in your code or answers.
