Hydra is a browser-based live coding environment for visual synthesis, enabling collaborative networked visual performance

Hydra, created by Olivia Jack (independent developer), is a browser-based live coding system for visual synthesis that can be used collaboratively over networks. It was mentioned in the book among the wave of groundbreaking new systems (alongside Orca, Flok, Improviz, Bespoke) developed by independent practitioners outside academia. Hydra is used frequently in audiovisual live coding collaborations, as in the Alexandra Cardenas and Olivia Jack ICLC 2019 performance. Its browser-based nature makes it immediately accessible without installation, supporting the live coding community’s preference for tools that lower barriers to entry.

Examples

In the Cardenas x Jack ICLC 2019 algorave set, Jack used Hydra for visuals while Cardenas used TidalCycles/SuperCollider for audio — a canonical example of AV live coding duo collaboration.

Assessment

What makes Hydra’s browser-based architecture specifically suited for networked collaborative visual live coding? How does Hydra’s visual output relate to audio in a typical AV live coding performance?
