API workflow comparison

Reqbook vs Bruno for repo-native API workflows

Compare Reqbook and Bruno for local API work: GUI collections, Git-friendly files, runnable Markdown notebooks, CI, and coding-agent context.

Short answer

Reqbook is the notebook for API workflows: docs, requests, tests, flows, and coding-agent context live as runnable Markdown in your repo. Bruno is strongest as a local-first API client with a desktop UI and Git-friendly collection files for manual request work.

Reqbook center

Repo-native API notebooks that run from CLI, local UI, CI, MCP tools, and agent skills.

Bruno center

Bruno is strongest as a local-first API client with a desktop UI and Git-friendly collection files for manual request work.

Main decision

Choose based on where your API source of truth should live and who needs to operate it.

Workflow comparison

Workflow need Reqbook Bruno
Primary artifact Readable Markdown API notebooks with requests, expected responses, assertions, flow notes, and agent context. Collection files designed around a local API client experience.
Human review Markdown reads like documentation and runs like a test. Files are versionable and Git-friendly, but the center is still request collection management.
Agent workflow Built-in skills and MCP tools let agents search, execute, diagnose, and update specs. Agents can inspect files, but the workflow is not centered on executable agent context.
CI contract checks rqb validate, rqb exec, rqb flow, and reports are core workflows. CI depends on the available CLI/export workflow for the collection.
Notebook semantics API explanation and execution live together in one Markdown file. Great local request UX, less focused on docs-as-code notebooks.

When Reqbook is the better fit

  • You want API docs as code, not just local request collections.
  • You want coding agents to operate API contracts directly from repo files.
  • You need Markdown diffs that explain behavior changes during pull request review.
  • You want multi-step API flows to become reviewable notebook artifacts.

When Bruno is the better fit

  • You mainly want a polished local desktop API client.
  • Your team prefers collection-driven manual exploration and does not need agent-specific context tools.
  • You want Git-friendly local files but not a Markdown-first documentation workflow.

Migration path

Move one endpoint or flow first. Keep the old tool during exploration if your team still needs it.

  1. Pick a Bruno collection endpoint that changes often or gets used by agents.
  2. Write or import the same endpoint into api-docs/ as a Markdown notebook.
  3. Add expected response notes and assertions that reviewers can understand.
  4. Run rqb validate and rqb exec in CI before moving more endpoints.
$ rqb init --name=my-api --yes
$ rqb import openapi ./openapi.yaml
$ rqb validate api-docs/
$ rqb serve
