reqweave

Read your service code; get ready-to-import API collections for every testing tool — with exhaustive request variants per endpoint.

reqweave statically analyzes a service codebase and generates native, ready-to-import collections for Postman, OpenAPI 3.1, Insomnia, Bruno, Hoppscotch, Thunder Client, and .http — covering not one request per endpoint, but a curated-yet-thorough set of request variants (happy path, all-optional, boundary/invalid values, one per response status, unauthorized). No more hand-building API requests, and no more collections drifting from code.

One source in → importable collections for every tool out.

Note

Status: functional for ASP.NET Core (REST + minimal APIs), Node/TypeScript (NestJS + Express), Python (FastAPI + Flask), and Java (Spring Boot). Build-mode reconciliation, OpenAPI import, and prebuilt SDK-free analyzer binaries are in. A Go analyzer is next on the roadmap. See the design spec and implementation plan.

Quick start

# all tools, standard depth, into ./reqweave-out
npx reqweave generate ./path/to/service --out ./reqweave-out --tools all --depth standard

Then import the generated files into your tool and start hitting the API.

./reqweave-out/
  postman/<svc>.postman_collection.json  (+ environment)
  openapi/<svc>.openapi.json
  insomnia/<svc>.insomnia.json
  bruno/  (bruno.json + *.bru + environments/Local.bru)
  hoppscotch/, thunder-client/  (collection + environment)
  http/<svc>.http  (+ http-client.env.json)

Commands

Command	Purpose
reqweave generate <path>	Generate collections. Flags: --lang auto|dotnet|ts|py|java, --out, --tools all|a,b, --depth minimal|standard|exhaustive, --base-url, --service, --build, --build-openapi FILE, --openapi FILE, --strict, --ir FILE.
reqweave list-endpoints <path>	List discovered endpoints.
reqweave inspect <path> <id>	Show the variants for one endpoint (with provenance).

Variant depth

• minimal — happy path only.
• standard (default) — happy path, all-optional, unauthorized (401) for [Authorize], one per declared error status, min/max boundaries.
• exhaustive — adds pairwise over optional-param presence and per-enum-member variants. Capped (reported in notes — never silent).

Consumption surfaces

• CLI / npm — npx reqweave … (above).
• MCP server — reqweave-mcp (stdio): tools list_endpoints, generate_collection, explain_variants for any MCP-capable agent.
• Agent Skill — skills/reqweave/ (progressive disclosure) for Claude and other agents.
• Claude marketplace plugin — .claude-plugin/.

Requirements

• Node.js ≥ 20 for the CLI/MCP.
• For analyzing .NET source: either a prebuilt analyzer binary (no SDK) or the .NET SDK. Resolution order:
  • --ir <file> / --openapi <file> — use an existing IR / OpenAPI doc (no analyzer at all).
  • REQWEAVE_ANALYZER — an explicit analyzer binary/dll you point at.
  • Prebuilt, per-OS package @reqweave/analyzer-<platform>-<arch> — a self-contained native binary installed automatically (as an optional dependency, os/cpu-gated) and checksum-verified before it runs. No .NET SDK needed.
  • The .NET SDK (dotnet run the analyzer) — the dev/source fallback.
• For analyzing Node/TypeScript source (NestJS/Express): nothing extra — analysis runs in-process via the bundled typescript parser. No SDK, no code execution.
• For analyzing Python source (FastAPI/Flask): nothing extra — a dependency-free, in-process reader. No Python runtime, no code execution.
• For analyzing Java source (Spring Boot): nothing extra — a dependency-free, in-process reader. No JVM/JDK, no code execution.

Design principles

• No code execution by default — static read; --build is opt-in.
• No network, no telemetry — your code stays local.
• Never leak secrets — {{placeholders}} + env templates with blank secret slots + a redaction pass.
• Deterministic — byte-stable output for clean diffs.

Architecture

A .NET (Roslyn) analyzer reads the codebase and emits a versioned, tool- agnostic Universal IR. A TypeScript core consumes that IR and owns the variant engine, all exporters, the CLI, and the MCP server — so each future language analyzer is a drop-in that emits the same IR.

codebase ─► reqweave-analyzer (.NET/Roslyn) ─► Universal IR (JSON) ─► variant engine ─► exporters ─► every tool
