Changelog

See what's new in Fathom

March 2, 2026

As we transition from a building phase to a shipping phase, transparency becomes our primary focus. We believe that a great product is not just about the code we write, but also how we communicate its evolution to our community. This is why we've launched the dedicated Changelog page, providing a single source of truth for every update, no matter how small.

In addition to the new changelog, we've invested heavily in launch polish. This includes automated SEO metadata and dynamic sitemaps to ensure our product is discoverable, as well as a brand refresh with a new site-wide favicon and high-definition logo modules. On the UI front, the navigation bar is now intelligently sticky across all breakpoints, and we've resolved persistent alignment issues in the Footer and FAQ sections to ensure a flawless experience on smaller screens.

February 28, 2026

February marked a major leap in how users interact with Fathom. Our goal has always been to make the platform feel less like a tool and more like an active collaborator. With the introduction of real-time voice indexing and interrupt handling, Fathom now reacts to your needs instantly, allowing for a more immersive and proactive development experience.

Beyond interaction, we've focused on making Fathom ready for teams of all sizes. We shipped a brand new pricing engine with standardized startup and enterprise tiers, alongside Smart Scoping for more granular repository analysis. We also underwent a comprehensive UI standardization, aligning padding and container widths across all core components and optimizing the mobile hero section with a high-performance video player. Important fixes were also landed, including a resolution for real-time tool-call flows and iOS-specific video playback bugs.

January 25, 2026

January was all about 'under the hood' power. To support the massive complexity of modern monorepos, we've integrated the first stable version of the Fathom Rust Engine. This provides a significant performance boost during indexing and more reliable analysis of cross-service dependencies. Combined with a fully Dockerized stack, Fathom is now more portable and secure than ever.

We also prioritized developer security and autonomy by introducing scoped API keys and OAuth application support. These features give you total control over how external services interact with your data, backed by a more robust CORS configuration and deep logging for all authentication attempts. We've also completely revised our technical documentation and READMEs to make the developer onboarding experience as smooth as possible.

December 15, 2025

We wrapped up 2025 by laying the collaborative foundations for Fathom. The launch of the Playground provides a dedicated space for node-focused chat, allowing developers to explore repository concepts in a lightweight, conversational interface. This launch includes our first release of the repository graph visualization system, helping users see their codebase structure in a completely new way.

To support our early user base, we've stabilized our core registration and database flows, optimizing MongoDB timeout configurations and session handling for high-concurrency environments. We also simplified the onboarding flow by removing legacy registration blocks and fixed intermittent connection timeouts during high-traffic cold starts, ensuring a stable foundation for the year ahead.
