Most AI tools offer free tiers to get you hooked. Here's what to look for:
- Usage limits: Check how many API calls, completions, or messages you get per month.
- Model access: Free tiers often give you older or smaller models. The best free tiers include flagship models.
- No credit card: The best tools let you start completely free without entering payment info.
- Open source: Self-hosted tools like Langfuse and Stable Diffusion are truly free — no limits, no catches.
All tools listed above meet at least one of these criteria. We update this page regularly as new tools launch or change their pricing.
