I build local-first software with explicit boundaries: tools that keep useful state under the user’s control, expose evidence instead of hiding decisions, and say clearly what they do not solve.
Currently building VeriSilo, a Windows-first, open-source browser environment isolation and privacy-auditing project for Chrome and Edge.
Developer profile · 中文 · Qiu’s Room · Writing · Email
Every Silo launches Chrome or Edge with its own managed data directory, keeping cookies, storage, cache, service workers, permissions, and history inside that environment rather than the default browser profile.
VeriSilo is explicit about its limits: it does not claim device impersonation, fraud bypass, TLS or QUIC modification, hardware isolation, or undetectability.
Pre-release engineering · Windows-first · Open source · Product site · Source
A local-first nutrition feedback workbench that connects meal photos, daily state, recent trends, and user corrections into a history that can improve the next decision.
Available · v0.2.0 · Local-first · Python · SQLite
A local-first activity radar for parallel AI coding agents. It brings running, waiting, permission-request, completed, and failed states into read-only desktop, dashboard, companion, and CLI views without storing prompts or transcripts.
Stabilizing · v0.5.0 candidate · TypeScript · Electron
A repeatable local Hadoop laboratory that connects environment setup, service inspection, MapReduce, and three-node failure and recovery into a guided learning path.

- Local-first — Keep useful work and private state on the user’s machine by default.
- Inspectable systems — Expose evidence, history, and capability state instead of hiding judgment behind a score.
- Explicit boundaries — Say what the software does not solve before marketing fills in the blank.
- Reproducible infrastructure — Turn setup and recovery into paths another person can repeat and verify.
- User-controlled data — Prefer deliberate export, correction, and deletion over silent synchronization.
Qiu’s Room is where I keep writing, guitar, games, relationships, and questions that have not turned into software.
