BluefiberPrivate preview

Ask what breaks before you change it.

Ask "what happens if we change X?" and get a cross-repo blueprint: the files to touch, API changes, and schema deltas, pushable to Linear or exportable as a coding-agent prompt. Underneath, a Rust scanner extracts your codebase into a per-organization Neo4j property graph that a chat agent queries.

a graph, not a guess

The mechanism

Answers from verified context. Not guesswork.

Each of these exists in the codebase. We name the mechanism so you can hold us to it.

  1. A graph, not a guess

    The agent can only reach the graph through typed semantic verbs and a scoped query builder, never raw Cypher. Blueprint validators reject any edge or repo that is not actually in the graph.

  2. Re-scanned on every push

    The graph is a versioned snapshot: GitHub webhooks trigger a re-scan, and the current version flips atomically when it completes. Versioned and current, not "live streaming". We say what it is.

  3. Blueprints as structured artifacts

    Not prose: files to touch, typed API changes (HTTP, gRPC, DB, queue), schema deltas, acceptance criteria, risks. Validated against a schema before you see it.

  4. Privacy-preserving scanning

    Only structural metadata ships to the graph. Function bodies, comments, and environment values never leave the scanner process.

What it does4 capabilities, all shipped

Cross-repo edges

A workspace manifest plus inference resolves calls across services, so blueprints span your system, not one repo.

Blast-radius visualization

Interactive dependency-graph view with lazy expansion to explore the impact surface of a change.

Push or export

Send a blueprint to Linear as a parent-and-children issue tree, or export it as a structured prompt for Claude Code, Codex, or Cursor.

Tenant isolation

Your graph is scoped to your organization: Postgres row-level security plus an org filter injected into every graph query, with a fuzz test asserting the filter is always present.

Where it standsIn private preview. Scanner, graph, chat, and the blueprint pipeline are built; the LLM paths are still being verified end-to-end and it is not yet deployed for outside users. Parses TypeScript/JavaScript and Python today.
