Skaftor is the system of record for AI-native software delivery. SpiderBrain is a Codebase memory & blast-radius graph over MCP. Here's how they compare — and when to choose each.
SpiderBrain is a coding-intelligence layer: a deterministic file graph that parses your codebase into a living memory, scores every node by severity and blast radius, surfaces load-bearing 'keystone' files and blind spots, and exposes all of it to AI agents over MCP. It's infrastructure — a brain you connect agents and applications to, with an API to build on.
This is the closest overlap with one specific Skaftor pillar: engineering memory and blast-radius analysis. The difference is that SpiderBrain is the memory/impact layer, while Skaftor is the delivery system that layer serves. Skaftor also captures intent, blueprints architecture, compiles and dispatches work orders, enforces approval gates and release confidence, and closes the loop with post-launch feedback — with its knowledge graph spanning intent and people, not only code structure.
If you want a best-in-class, source-free codebase graph to give any agent deep project memory and impact scoring, SpiderBrain is built precisely for that and is a natural complement to agent workflows. If you want that memory embedded in a governed pipeline from intent to production, Skaftor provides the whole system with memory as one of its layers.
| Capability | Skaftor | SpiderBrain |
|---|---|---|
| Codebase dependency graph | Yes — part of the knowledge graph | Yes — deterministic file graph, a core strength |
| Blast-radius / severity scoring | Yes | Yes — a core strength |
| Memory exposed to agents over MCP | Yes | Yes — a core strength |
| Memory of intent, decisions & people (not just code) | Yes — intent↔blueprint↔work order↔code↔feedback | Code-structure focused; captures decisions/changes |
| Intent capture (requirements/blueprints) | Yes | Not its focus |
| Agent-executable work orders | Yes | Not its focus |
| Approval gates & governance | Yes | Not its focus |
| Release confidence / spec-drift workflow | Yes | Drift signals in the graph |
| Build-on API / infrastructure | Product + MCP + CLI | Yes — Brain API to build products on |
| Scope | Whole lifecycle system of record | Memory & impact layer for agents |
They overlap on engineering memory and blast-radius analysis, but at different altitudes. SpiderBrain is a deterministic codebase memory and impact-scoring layer you connect agents to over MCP. Skaftor is the full delivery system — intent capture, work orders, orchestration, governance — with a knowledge graph that spans intent, code, and people.
Conceptually yes: SpiderBrain specializes in the code-structure memory and blast-radius layer, while Skaftor governs the whole lifecycle. A team could use a dedicated intelligence layer alongside a delivery system, though Skaftor includes its own knowledge graph and blast-radius signals.
