Developers ♡ FizzlyAPI
See what developers say about our high availability and minimal experience.
Previously I needed two codebases for OpenAI and Claude. With FizzlyAPI, I just change one parameter. Super smooth! Latency is also very low, highly recommended.
We've been using FizzlyAPI in production for three months now, the stability is amazing. My favorite is the smart routing feature, saving us at least 30% on API costs.
For indie developers, Fizzly's pay-as-you-go and unified billing is a lifesaver. No more managing multiple credit card bills. The UI design is also super nice!
