The score comes from our model.

• Show HN: Pseudogress – high performance PostgreSQL mock for testing · score 7.3

  Pseudogress is a high-performance PostgreSQL mock server written in Rust that simulates many virtual databases for load-testing PostgreSQL clients, especially multi-tenant PostgREST. It records real database responses and replays them with configurable latency and faults, allowing thousands of connections without a real database. The project uses a class-based configuration, records time-aware data, and provides a Nix-based build.

• Show HN: Ranet3 – High performance policy routed IPsec mesh SD-WAN · score 7.3

  Ranet3 is a high-performance policy-routed IPsec mesh SD-WAN that provides stable public IPv4/IPv6 addresses for devices behind dynamic NAT. It stands out for its ability to run on diverse platforms including MacBooks and its focus on policy-based routing for mesh networks.

• Show HN: Hlock – an agent harness lockfile and performance resolver · score 7.0

  hlock is a lockfile and performance resolver for AI agent harnesses, pinning models, MCP servers, skills, and config into a portable harness.lock that can be versioned and rehydrated anywhere. It also benchmarks and optimizes your agent stack against eval packs to find the best combination of success rate, cost, and latency. The project stands out by treating agent setups as reproducible dependencies, similar to package managers but for the entire agent harness.

• Show HN: BeamDisk – High Performance iSCSI Initiator for macOS · score 6.3

  BeamDisk is a high-performance iSCSI initiator for Apple Silicon Macs that works without kernel extensions, installable via the Mac App Store. It targets a real gap left by the lack of native iSCSI support on modern macOS, with impressive throughput benchmarks and support for standard targets like TrueNAS and LIO.
