Latest News
Published “CSS does your tooltip positioning now,” covering CSS anchor positioning, popovers, and anchor-size() as alternatives to JavaScript positioning.
Updated the AI Flight Recorder changelog while continuing the open-source package and documentation work.
Added the AI Flight Recorder VS Code extension, a custom editor for .flight files.
Created the AI Flight Recorder repository and published the initial open-source implementation.
Products & Services
An MIT-licensed open-source developer tool and SDK for recording, replaying, and inspecting AI-application interactions, including prompts, streamed tokens, tool calls, latency, and cost. It includes a DevTools-style timeline, .flight file export/import, provider adapters, a VS Code extension, and OpenTelemetry export.
The developer-facing SDK for AI Flight Recorder, including FlightRecorder, provider adapters, plugins, transports, and Node.js filesystem transport.
The core domain types and engine for AI Flight Recorder, covering sessions, events, recording, and replay.
A static audit tool for environment variables in Node.js and Next.js projects.
Market Position
Matt Smith's work is positioned as independent, front-end-first engineering and open-source tooling. AI Flight Recorder differentiates around a developer-tooling workflow that records and replays AI sessions locally as portable .flight files, rather than relying only on post-hoc console logs; its provider adapters, VS Code viewer, and OpenTelemetry export broaden interoperability.
