What customers say Speakeasy changed
Figures and quotes as Speakeasy and its customers published them, each tied to its source. We quote, we do not measure the result.
“Right before adopting Speakeasy, SDK maintenance was getting out of control. We had one developer spending at least 5 hours/week generating new SDKs for every API release. And now that mental load is just gone.”
Clément SalaünFormance Co-Founder & CEO, Formance“The quality of the code we get from the Speakeasy SDK generation is much higher than the OpenAPI generator.”
David BiesackChief API Officer at Apiture, Apiture“Using a non-automated approach toward SDK generation would have been costly from an ongoing maintenance perspective. Automating our SDK production with Speakeasy allows us to cost-effectively cover our customers' language requirements and ease their integration cost quite a bit.”
