IT's FOSS, Friday, April 10th, 2026
This self-hostable enterprise AI client lets you bring your own models and keep your data off third-party servers.
MZLA Technologies Corporation, the Mozilla Foundation subsidiary behind Thunderbird, has announced Thunderbolt, an open source, self-hostable AI client for organizations that want to run AI on their own infrastructure.
The project is funded through investment from Mozilla and is a standalone product, separate from Thunderbird, built by a different team within MZLA that's focused on enterprise AI products.
