BMAD comparison: spec-sync docs
Comparisons
SpecSync and BMAD Method operate at different layers. BMAD is an agent-led product development system spanning discovery, product requirements, UX, architecture, stories, implementation, review, and testing. SpecSync is a deterministic contract and evidence engine that checks durable module truth against the repository.
Practical boundary
| Question | SpecSync 6.0 | BMAD 6.10 core |
|---|---|---|
| Fast path for a small change | Adaptive change interview and lifecycle | Quick Dev clarifies, plans, implements, reviews, and presents |
| Full product planning | Focused change artifacts and module requirements | Analysis, PRD, UX, architecture, epics, and stories |
| Specialized agent roles | Uses the developer's existing agent | Analyst, PM, architect, developer, UX, and technical-writer agents |
| Contextual next-step guidance | Deterministic status and next action | bmad-help inspects available artifacts and recommends workflows |
| Human review | One digest-bound scope approval plus independent scoped PR review | Workflow checkpoints and review decisions |
| Requirements and test governance | Stable IDs plus required verification evidence | Process traceability; stronger optional TEA workflows |
| Real export/schema parsing | Built into the deterministic core | Not a core BMAD responsibility |
| Stale tested-input invalidation | Deterministic blocking gate | Agent/workflow dependent |
Where BMAD is stronger
- Guided ideation-to-delivery product development.
- Quick Flow, full Method, and Enterprise planning tracks.
- Specialized roles, facilitation, implementation readiness, and contextual help.
- Optional Test Architect workflows for deeper risk, traceability, and release review.
Where SpecSync is stronger
- Deterministic bidirectional checks against real exports, files, dependencies, and schemas.
- One shared lifecycle regardless of which human or coding agent performs the work.
- Digest-bound approvals and verification tied to exact delivery inputs.
- Atomic canonical deltas plus append-only correction, reopen, and archive evidence.
Choosing
Choose BMAD when the primary need is a guided product-development method with specialized agents. Choose SpecSync when CI must prove that durable technical contracts agree with implementation and current human-approved evidence. Use both when BMAD should shape and deliver the product while SpecSync owns the enforceable module boundary.
