Flocking Alternatives

Looking for an alternative to Flocking? It's javaScript audio synthesis framework using declarative JSON specs, aimed at artists and experimental web sound. Below are 20 other synthesis & dsp tools for making music with code — how each compares, and when it's the better choice. Every option is verified against its own source.

Heads up: Flocking is no longer actively maintained (last activity 2022), so a maintained alternative below may be the safer long-term pick.
