Built to map your codeDeterministic structure • Diagram-ready output

Map code structure
before explanation.

Confused about the structure of a JS/TS or Python file? Upload one file and we return a deterministic ProjectMap of blocks (imports, exports, types, functions, classes/methods) plus edges (best-effort calls).

Deterministic in, deterministic out. No AI-hallucinated structure.

How it works →View roadmap below ↓Commercial / API embedding (contact)→
Core idea: FileFig doesn’t “solve code problems.” It returns a map so the code stops feeling opaque.

What you send → what you get

Single-file extraction returns deterministic structure you can render anywhere: blocks + edges.

// input: a single file
import { normalizeHeaders } from "./headers";

export const X = 1;

export function normalizeRequest(req) {
  const headers = normalizeHeaders(req.headers);
  const ip = extractClientIp(req, headers);
  return { headers, ip };
}

// output: ProjectMap
// blocks: IMPORT | EXPORT_CONST | TYPE | INTERFACE | FUNCTION | CLASS | METHOD
// edges:  CALLS (best-effort)

How it works

  1. Send a single file of code (JS/TS or Python for now).
  2. We return a deterministic ProjectMap (blocks + edges).
  3. View it in the FileFig Viewer (Plus) or plug it into your own tooling.

Designed to feel like HTML/CSS: see the structure first, then learn the details.

Roadmap

  • Plus: FileFig Viewer (proprietary) + exports (SVG/PNG/PDF) and richer rendering
  • Open-source (planned): ProjectMap Annotation Tool (notes/tags/labels)

Privacy / zero-retention policy

FileFig is designed to be safe by default:

When analytics are added, they will be metadata-only (counts, latency), never raw code.

Free for individuals • paid for embedding

Use single-file FileFig for learning and personal work. If you want to embed FileFig into an app, a SaaS product, a commercial workflow, or resell it as a feature, use a commercial plan.

Planned: Plus adds the FileFig Viewer and export formats for professional artifacts.
