01
GitNexus, with 45k GitHub stars, is a Knowledge Graph Kernel that unifies every codebase in your org into one source of truth your coding agents can query. It resolves your code into a deterministic graph, so agents get exact callers, imports, and impact instead of embedding guesses, across every repo and SCM you run. On our public benchmark at https://www.akonlabs.com/benchmarks, coding agent runs are 51% cheaper with GitNexus connected. It works with any agent over MCP.
02
Traccia is a vendor-neutral AI Agent Control Plane built for teams running autonomous agents in production. Observe agent behavior, evaluate performance, govern actions with policies and runtime controls, and maintain an auditable trail of what happened. It comes with an open, developer-first SDK and OpenTelemetry support, so Traccia works across models, frameworks, and existing observability stacks. That means you can control your agents without being locked into a single AI vendor.
03
Most meeting notes apps demand your recording, your account, and your credit card. Ulpaso doesn't. Just press record, and it captures both your microphone and system audio, transcribes them right on your Mac, and saves everything as an editable Markdown file. No cloud upload, no login required, and no monthly subscription for a basic checklist. It's just you, your Mac, and your notes.
04
ChannelOS is a local-first TV system for Windows that transforms the media you already own into persistent, programmable channels. Create your own stations, set schedules, browse a live cable-style TV guide, watch on demand, and flip channels using a couch-friendly interface. There's no need for an account, cloud service, or uploading your media anywhere. The current alpha is completely free and open source under the MPL-2.0 license.
05
The Computable GPU Index (CGI) provides a transparent, USD-denominated price per GPU-hour, derived from the published on-demand rental rates of a fixed set of cloud providers. The methodology is mathematically rigorous and fully reproducible, so anyone can verify each calculation. This gives you a reliable benchmark for comparing GPU costs across the market.
