TEN Framework.
A cross-language framework and runtime for realtime conversational voice agents, with reusable extensions and a visual agent builder.
What you are adopting
Repository and documentation checked 2026-07-17. Always re-check license and release activity before adoption.
When TEN Framework belongs on the shortlist
The strongest framework is the one that matches your ownership boundary, not the one with the longest provider list.
Best fit
Teams that need a compiled realtime core, multimodal extensions, and a visual builder.
Operational trade-off
The repository describes itself as open source, but its root license adds restrictions. Review the exact license before commercial redistribution.
Cost model
Open-source code does not make the full call free. Budget separately for speech models, language models, telephony, phone numbers, recording, storage, observability, compute, support, and the engineering time needed to keep a realtime service healthy.
Inspect the project directly
Repository metadata can drift. Use the source and current documentation for a final technical or legal decision.
