The score comes from our model.

• Show HN: Whospair – a serverless Android messenger over Tor, with voice calls · score 7.5

  Whospair is a serverless Android messenger that uses Tor hidden services for direct peer-to-peer communication, eliminating central servers and accounts. It combines strong end-to-end encryption, voice calls, and advanced privacy features like duress PIN and face-detection screen protection, all packaged in a single APK with self-updating over Tor.

• Show HN: DeadBolt – a local execution gate for agent tool calls · score 7.5

  DeadBolt is an execution gate that sits at the point of action for AI agent tool calls, enforcing policy, approvals, and operator kill switches before side effects occur. It provides embedded Rust, sidecar, and MCP proxy integrations with detailed evidence logging and structured control primitives, addressing a real gap in agent safety and governance.

• Show HN: Charter, field-level control over agents' calls into customer accounts · score 7.3

  Charter is a Python library that gives field-level control over what an LLM agent can read and send when calling into customer accounts via APIs. Each tool is a Pydantic model mirroring the API schema, with app-supplied context (like account ownership) and validation rules enforced before any request leaves the process. It also trims responses, builds wire formats, and produces a reviewable egress map, filling a real gap for teams deploying agents against customer data.

• Show HN: ZapFast, a native WhatsApp client with voice and video calls on Linux · score 7.3

  ZapFast is a native, cross-platform WhatsApp client built in Rust with egui, linking to your phone as a companion device. It offers voice/video calls, media sharing, encrypted local storage, and multiple accounts, with performance far better than WhatsApp Web. Its novelty lies in being a lightweight, native implementation outside the Electron/browser stack, leveraging the whatsapp-rust protocol library.
