Stoplight built its reputation on design-first API development: a visual OpenAPI editor, Git-backed specs, and hosted documentation. After SmartBear acquired Stoplight in 2023, its product direction changed. Stoplight Studio has seen little activity, and customers report being guided toward SmartBear API Hub during renewals. If you are evaluating a Stoplight alternative, now is a practical time to validate a migration path.
Apidog is a strong Stoplight alternative for teams that want to keep a design-first, Git-friendly workflow while adding API testing, mocking, debugging, and CLI-based automation in one platform.
What’s happening to Stoplight
Three changes make it worth reviewing your current setup.
- The platform is being absorbed. SmartBear has been incorporating Stoplight platform features and open-source tooling—Spectral, Elements, and Prism—into API Hub. Renewals can mean moving to a different product than the one originally adopted. APIs You Won’t Hate covered this transition in “Goodbye Stoplight?”
- Stoplight Studio has stalled. The desktop editor that made Stoplight popular has not received meaningful updates since the acquisition. Depending on an unmaintained editor adds risk to a design workflow.
- Testing requires a second stack. Stoplight’s entry plan is listed at $44 per month and focuses on design and documentation. API testing, assertions, test reporting, and CI execution require external tools.
For a broader comparison, see the top 10 Stoplight alternatives and Stoplight Studio alternatives.
Why Apidog is the top pick
Apidog is an API development platform used by more than 500,000 developers. For Stoplight users, the migration goal is straightforward: preserve spec-first development while consolidating the tooling around the spec.
Keep your design-first workflow
Use a spec-first project for file-based OpenAPI workflows:
- Store OpenAPI files in Git.
- Connect the repository to Apidog.
- Edit the API in a visual designer.
- Keep the repository as the source of truth.
- Use branches for parallel design work.
The same spec can drive requests, mocks, tests, and documentation. When a schema changes, downstream artifacts can follow the updated definition instead of requiring manual updates across separate tools.
Build tests without adding another platform
Apidog includes a visual test builder for:
- Response assertions
- Dynamic variables
- Multi-step scenarios
- Scheduled runs
- Performance testing
- Online test reports
- Self-hosted runners
You can also run scenarios from Jenkins, GitLab CI, or GitHub Actions using the Apidog CLI and generate HTML reports as part of the build process.
Generate mocks from schemas
Stoplight users often run Prism separately for mocking. Apidog can generate mock responses from JSON Schemas without a separate mock-server configuration.
Use the built-in mock engine to:
- Provide frontend teams with endpoints as soon as the spec exists.
- Generate schema-based example responses.
- Run mocks in the cloud or self-host them.
- Add scripts when a scenario needs custom response behavior.
Publish interactive API documentation
Apidog supports hosted API documentation with:
- Custom domains
- Custom layouts
- Markdown pages
- Versioning
- Interactive “try it” requests

Automate workflows with MCP and CLI
Apidog provides an MCP server for exposing API specs to AI assistants, visual MCP debugging, and a CLI for terminal-driven API operations.
npm install -g apidog-cli
apidog spec sync --project-id my-project
The CLI can support workflows involving Claude Code, Cursor, and Codex for docs, mocks, tests, and CI automation. Learn more in What is Apidog MCP Server.

What to do with Spectral, Elements, and Prism
SmartBear has been folding Stoplight tooling into its API Hub portfolio. Each open-source tool has a different migration decision.
Keep Spectral
Spectral is open source and can continue running in any CI pipeline. If your OpenAPI files remain in Git, Spectral can lint the same files that Apidog syncs.
Apidog does not provide a Spectral-style style-guide linter, so retaining Spectral in CI is the recommended setup.
Retire Elements
Elements renders OpenAPI specifications as documentation that you host and maintain. Apidog hosted documentation can replace that role with custom domains, layouts, Markdown pages, versioning, and an interactive console.
Retire Prism
Prism requires you to deploy, configure, and maintain mock infrastructure. Apidog’s smart mock engine can generate mocks directly from JSON Schemas, with cloud and self-hosted deployment options plus scripts for custom behavior.
A practical rule: keep the open-source tool that costs little to operate, and retire tools that have become internal infrastructure.
Migrate from Stoplight in five steps
Because both platforms use OpenAPI, the migration process is direct:
- Create a spec-first project in Apidog.
- Import OpenAPI or Swagger files.
- Connect the Git repository so it remains the source of truth.
- Import Markdown documentation, JSON Schema models, and referenced images, then validate the output.
- Invite the team and configure roles, permissions, and environments.
For enterprise deployments, Apidog supports SSO with Okta and Microsoft Entra ID, SCIM provisioning, project-level role-based access, and GDPR-compliant European deployment on AWS Ireland and Germany. Support is available through Discord, Slack, email, and scheduled calls.
Validate one API before migrating everything
Avoid a large-bang migration. Choose one service, rebuild its complete workflow, and compare the result with your current Stoplight process.
1. Import the spec
Create a spec-first project and import the OpenAPI file for one service. Endpoints, schemas, and descriptions should be available immediately.
2. Connect Git
Connect the repository containing the specification. Keep Git canonical, sync visual-editor updates as standard OpenAPI, and use branches for work in progress.
3. Publish documentation
Enable documentation publishing and configure a custom domain. The output is generated from the same spec and can include endpoints, models, Markdown pages, and an interactive console.
4. Enable mocking
Turn on the smart mock engine. It can read JSON Schemas and begin serving responses without a separate configuration file or mock-server deployment.
5. Add a test scenario
Create a multi-step scenario:
- Call an endpoint.
- Assert on the response.
- Extract a value.
- Pass that value to the next request using a dynamic variable.
This is a useful evaluation step because it covers a workflow that Stoplight does not provide natively.
6. Run the workflow in CI
Install the CLI and add the scenario to your pipeline:
npm install -g apidog-cli
apidog spec sync --project-id my-project
Jenkins, GitLab CI, and GitHub Actions are supported. For available commands, see how to manage APIs with the Apidog CLI.
By the end of this evaluation, you should have one API designed, documented, mocked, tested, and connected to CI from a single specification.
Compare the actual cost of the stack
Stoplight’s entry plan is listed at $44 per month for design and documentation. Testing requires another tool, while Prism-based mocking adds deployment and maintenance work.
Apidog’s free plan covers four users and includes design, documentation, testing, mocking, debugging, and CLI access. Paid plans start at $9 per user per month.
The useful comparison is not only $44 vs. $9. Compare:
- Design and documentation plus separate testing and mocking infrastructure
- Against a platform that combines design, docs, mocks, tests, debugging, and CLI automation
When staying with Stoplight still makes sense
Staying put may be reasonable if your team:
- Only publishes reference documentation.
- Does not need integrated testing or mocking.
- Has stable SmartBear contract terms.
- Is satisfied with its existing external test and mock tooling.
Spectral also remains a solid standalone linter. You can continue using it with Git-based OpenAPI files regardless of whether you adopt Apidog.
Frequently asked questions
Does Apidog support design-first development like Stoplight?
Yes. Apidog spec-first projects keep OpenAPI files as the source of truth, support Git sync and branches, and can generate docs, mocks, and tests from the specification.
Can I import existing Stoplight projects?
Yes. Export OpenAPI specifications from Stoplight and import them into Apidog. Schemas, API structure, and documentation can carry over. Markdown pages and JSON Schema models can also be migrated.
Is Apidog cheaper than Stoplight?
Stoplight’s entry plan is listed at $44 per month for design and documentation. Apidog has a free plan for four users across the platform, while paid plans start at $9 per user per month.
What happens to hosted Stoplight documentation?
Republish it from Apidog with a custom domain, custom layout, versioning, and interactive requests. See the top Stoplight alternatives comparison for more context.
Can Git remain the source of truth?
Yes. Connect your repository to a spec-first project. OpenAPI files in Git remain canonical, while the visual designer reads and writes those files. Branches support parallel design work without changing your existing review flow.
Do I need to stop using Spectral?
No. Spectral is open source and independent from the Stoplight platform. Keep it in CI to lint the same OpenAPI files that Apidog syncs from your repository.
Make the move on your terms
Platform transitions are easier when you validate them before a renewal deadline. Download Apidog, import one OpenAPI specification, and rebuild one workflow end to end: design, mock, test, and publish.
