Mozilla Launches Thunderbolt: Open-Source Self-Hostable Enterprise AI Client

The Register·high signal

Mozilla's for-profit arm MZLA Technologies launched Thunderbolt on April 16, an open-source AI client for enterprises who want sovereign AI infrastructure without routing data through Copilot, ChatGPT Enterprise, or Claude Enterprise. Built on deepset's Haystack agent framework, it ships with native apps for Linux/macOS/Windows/iOS/Android, supports Anthropic/OpenAI/Mistral/Ollama out of the box, and connects to enterprise data sources via RAG. For builders running their own AI stack, this is the first serious open-source alternative to commercial AI workplace tools.
