Apidog is an all-in-one API platform for design, debugging, mocks, tests and documentation. Teams keep every API asset synced to one OpenAPI spec.
About Apidog
What Is Apidog
Apidog is an API design tool at heart, an API development platform built around a design-first workflow. Instead of juggling a documentation tool, an HTTP client and a mock server, you write your API spec once and let the rest follow from it. The spec drives design, requests, mocks, tests and published docs, and a change to one shows up in all of them.
The problem it solves is drift. Most teams keep specs in one place, requests in another and tests somewhere else, then spend their week re-syncing manual work. Apidog turns that into a single source of truth. It also handles real teamwork: branches, roles, access control, and a free tier that covers up to four members.
Two limits matter before you commit. The free plan caps teams at four people, so larger groups pay per seat. And some advanced features, like self-hosted runners and SCIM provisioning, sit behind the enterprise tier.
Getting Started
- Sign up for a free account, then download the desktop app for Mac, Windows or Linux or open the web version
- Create a project and import an existing OpenAPI or Swagger file, or start a fresh spec and define endpoints visually
- Send requests, validate responses against your spec, and generate mocks straight from the defined schemas
- Build test scenarios, run them in CI/CD, and publish your documentation from the same project

Key features
Visual API Design
You describe endpoints in a visual editor and Apidog writes the OpenAPI, JSON and XML schemas as you go. Reusable components keep big specs consistent, and branches let you test changes without disturbing the main version.
Auto-Validated Debugging
Send a request and Apidog checks the response against your API spec on the spot, so a mismatch surfaces the moment it happens. It speaks HTTP, REST, GraphQL, SOAP and WebSocket, and it runs Postman scripts without changes.
Smart Mock Server
Apidog works as an API mocking engine: it reads field names and schemas, then returns believable mock data with no setup. Frontend teams get endpoints to build against before the backend exists, and custom rules can shape responses for edge cases.
Visual Automated Testing
Add an endpoint and turn it into a test case, then lay out assertions, loops and branching by dragging blocks. The same scenarios run in GitHub Actions, GitLab CI or Jenkins, and test reports stay online.
Interactive Documentation
Your spec turns into a polished API documentation site with versioning, custom domains and a Try It Out panel that sends real requests. Code samples generate in 20-plus languages, and you can match the layout to your brand.
Team Collaboration and Databases
Real-time sync, role-based permissions and branches keep a whole team on the same page. Apidog also connects to MySQL, PostgreSQL, Oracle, SQL Server and ClickHouse to pull data into requests and pre- or post-processors.
Pros and cons
Pros
- One spec drives design, mocks, tests and docs, so API changes stop turning into manual re-syncing
- Free plan supports teams up to four members with unlimited runs, projects and requests
- Postman scripts and collections import without rewriting, which makes it an easy Postman alternative to adopt
- Readable interactive docs with Try It Out and custom domains need no extra tooling
- AI agents can manage API assets through the CLI and MCP support
Cons
- Browser-based use can't reach internal network APIs, so private services need the desktop app
- The free tier stops at four seats, which pushes growing teams into paid plans fast
- Enterprise features like SSO, SCIM and self-hosted runners sit on the top plan only
- The full feature set has a learning curve, so a solo developer testing one endpoint may find it heavier than a plain HTTP client
Frequently asked questions
Yes. Apidog has a plan that costs nothing and covers up to four team members, with unlimited projects, requests and test runs. Paid plans add more domains, storage and history.
