Pace vs Shiro

Choosing between Pace and Shiro?

Shiro is local-by-default, cloud when you ask, and it's open source under a MIT license. It calls itself "Local-first autonomous agent — watches screen, spawns parallel sub-agents, MCP ecosystem.".

Where Pace differs: Shiro's parallel sub-agents and hybrid RAG knowledge graph are architecturally beyond Pace's single-thread agent loop. Pace has the tier picker, trust surfaces, and recipe library Shiro doesn't ship. Shiro's meeting mode is a surface Pace could add.

The full breakdown is below — what Shiro is genuinely good at, its stack, and the honest line on where Pace diverges, including where Pace is behind. For the whole field in one place, see every macOS voice agent compared.

What it's good at

  • Parallel sub-agents with atomic SQL checkout, persona injection, depth & budget guards.
  • Hybrid RAG using sqlite-vec + FTS5 in one SQLite file — live knowledge graph updates on every tool call.
  • Meeting mode with ScreenCaptureKit audio capture + live action item extraction.

If Shiro shipped something I missed or got cheaper since, email me and I'll update this page.
