MZLA Technologies Corporation, the Mozilla Foundation subsidiary behind Thunderbird<\/a>, has announced Thunderbolt<\/a>, an open source, self-hostable AI client for organizations that want to run AI on their own infrastructure.<\/p>\n

The project is funded through investment from Mozilla<\/a> and is a standalone product<\/strong>, separate from Thunderbird, built by a different team within MZLA that’s focused on enterprise AI products.<\/p>\n

Offered under Mozilla Public License 2.0<\/strong>, Thunderbolt offers an AI workspace where users can interact with AI through chat, search, and research, connect to enterprise data, and choose the models and tools that fit their needs.<\/p>\n

It runs natively on Linux<\/strong>, Windows<\/strong>, macOS<\/strong>, iOS<\/strong>, and Android<\/strong>, with a web client also being made available.<\/p>\n

A thing to note\u2026<\/h2>\n

You should know that Thunderbolt ships with telemetry on by default<\/strong>.<\/p>\n

According to the project’s telemetry documentation<\/a> on GitHub, it uses PostHog<\/a> to collect usage data covering chat activity, model selections, settings changes, and location information. <\/p>\n

This can be switched off in settings, and the project states no personally identifiable information<\/a> (PII) is collected without explicit consent.<\/p>\n

Who is it for?<\/h2>\n

The intended audience<\/strong> for this could be organizations with strict data residency or compliance requirements. So think healthcare providers, legal firms, and financial institutions that cannot afford sensitive internal data flowing through third-party AI services.<\/p>\n

As for its competition, Thunderbolt is a direct challenge to Microsoft Copilot<\/a>, ChatGPT Enterprise<\/a>, and Claude Enterprise<\/a>. In the open source space, it sits alongside tools like Open WebUI<\/a> and LibreChat<\/a>, both of which offer self-hosted AI frontends<\/a>.<\/p>\n

Announcing Thunderbolt, the CEO of MZLA Technologies Corporation, Ryan Sipes<\/a>, added that:<\/p>\n

AI is too important to outsource. With Thunderbolt, we\u2019re giving organizations a sovereign AI client that allows them to decide how AI fits into their workflows \u2013 on their infrastructure, with their data, and on their terms.<\/p><\/blockquote>\n

What can you expect?<\/h2>\n
\"this<\/figure>\n

Thunderbolt connects to frontier models<\/strong> from Anthropic, OpenAI, and Mistral, handles local inference through Ollama<\/a>, and accepts custom providers, with the workspace offering Chat<\/em> and Search<\/em> modes.<\/p>\n

It can also handle scheduled work<\/strong>, pulling together briefings, tracking topics over time, or kicking off actions when set conditions are met.<\/p>\n

deepset’s Haystack<\/a> integration ties the client into enterprise agent and RAG<\/a> pipelines within the same architecture, whereas MCP<\/a> (Model Context Protocol) support is in preview, and ACP<\/a> (Agent Client Protocol) is in active development with an April 2026 target<\/a>.<\/p>\n

How to get it?<\/h2>\n

You can get started with Thunderbolt by visiting thunderbolt.io<\/a>. Organizations interested in enterprise deployment, professional support, or custom development can get in touch with the team<\/a>.<\/p>\n

As for the source code, it lives on GitHub<\/a>. <\/p>\n

Thunderbolt<\/a><\/div>\n

Other than that, the FAQ<\/a> does mention that a Thunderbolt version for regular users<\/strong> is on the cards, but there’s no release date for it yet.<\/p>\n
