OverkillOS vs Kiro
Read on 23 September 2026 from Kiro's own pages (sources below). Where they are better, we say so.
| OverkillOS | Kiro | |
|---|---|---|
| Memory | Three tiers: QUICKSTART (~300 tokens) every boot, MEMORY on demand, ARCHIVE; global and per project | Steering files (workspace, global, cloud) with conditional loading |
| Boot protocol | Yes: Live State Block + a fixed four-file boot | Always-included steering and AGENTS.md each interaction |
| Research / PRD pipeline | Research-to-PRD per area behind a four-part pre-PRD gate | requirements → design → tasks, in the IDE, CLI and web |
| Verification gates | Binary gates, evidence rows, no-regression rule (by instruction, not enforced by CI) | Property-based correctness testing and hooks |
| IDE / agent support | Cursor first; playbooks for Antigravity and OpenClaw; no Claude Code adapter yet | Kiro is its own IDE |
| Dashboard / app | Local control plane (21 screens); no installer, not hosted | The IDE itself |
| Licence | MIT; the kit is shared through early access | Proprietary |
| Price | Nothing for sale | Free (50 credits) to $200/user/month |
Where Kiro is better
- Spec-driven development built into a full IDE, with automated hooks and tests.
Where OverkillOS is different
- Works inside the IDE you already use; plain markdown, no new editor.
- No subscription: nothing is sold.
