The Best Insomnia Alternative

Insomnia is a capable API client, but it is still primarily a client: send requests, inspect responses, and debug issues. When your workflow also needs documentation, mocks, automated tests, and team collaboration, you must connect separate tools and keep their data synchronized yourself.

Why developers look beyond Insomnia

The trust issue did not disappear overnight

When Kong shipped Insomnia 8.0 in 2023, it required an account and moved local data toward cloud sync. After user feedback, Kong restored local-only storage in Insomnia 8.3. Insomnia now supports Local Vault, Git Sync, and Cloud Sync.

That was a meaningful correction. But the Insomnia 8.0 release also prompted many developers to evaluate alternatives. Once you export collections and test another tool, the assumed switching cost often turns out to be a few hours rather than a major migration project.

For a broader comparison, see 17 best Insomnia alternatives.

What happened in the Insomnia 8.0 storage change

The timeline explains why developers started searching for alternatives:

1. 2023: Insomnia 8.0 shipped. The app required a Kong account, and data that had previously stayed on the local machine moved toward cloud sync.
2. Developers pushed back. API collections can contain tokens, internal hostnames, and unreleased endpoints. Teams objected to changing the storage model without an explicit choice.
3. October 2023: Insomnia 8.3 shipped. Kong restored local-only projects through Local Vault.
4. Today: Insomnia has three storage modes. Use Local Vault for local-only work, Git Sync for spec-in-repository workflows, or Cloud Sync for hosted collaboration.

The storage model was corrected, but many users had already exported their collections and compared other options.

Insomnia stops at debugging

Run through a typical API delivery workflow and the gaps are clear:

• Documentation: Insomnia does not publish API documentation. Teams use a separate docs tool and synchronize it manually.
• Mocking: There is no smart schema-based mock engine or cloud mock server for frontend teams.
• Automated testing: Insomnia provides basic test suites, but not visual test orchestration, scheduled runs, performance testing, online reports, or a self-hosted runner. CI requires the inso CLI. See the best Insomnia CLI alternatives.
• Design sync: Insomnia can store an OpenAPI definition, but requests and the spec are not automatically synchronized.

Every gap adds another tool, subscription, and synchronization task.

The alternative: Apidog

Apidog is an API development platform used by over 500,000 developers. It combines design, debugging, testing, mocking, and documentation around a shared API specification.

Instead of maintaining separate request collections, documentation pages, mock definitions, and test assets, update the API spec once and keep endpoints, docs, mocks, and tests aligned.

Use one workspace across the API lifecycle

Apidog supports debugging for HTTP, GraphQL, WebSocket, SSE, SOAP, and gRPC. It also includes pre-request and post-request scripts, response validation, and database connections.

From the same workspace, you can:

• Publish interactive API documentation from your spec with custom domains, custom layouts, Markdown pages, versioning, and a live “try it” console.
• Generate schema-based mocks from JSON Schemas without manually writing mock definitions.
• Build automated test scenarios with reusable steps, variables, assertions, and data passing between requests.
• Run tests in CI with GitHub Actions, GitLab CI, or Jenkins.
• Schedule suites, run performance tests, and share reports with the team.

Keep sensitive projects local

If storage control is your primary concern, Apidog provides an Offline Space for sensitive API data. For collaborative work, use shared workspaces with role-based permissions and project-level access controls.

This lets teams use local-only storage for internal APIs while using shared projects for APIs that require collaboration.

Add AI-assisted API workflows

Apidog includes an MCP server that exposes API specifications to AI assistants, a visual MCP client for debugging MCP servers over STDIO and streamable HTTP, and a CLI for agent-driven workflows.

Install the CLI and its agent skill:

npm install -g apidog-cli
npx apidog-cli install-skill

With the CLI, tools such as Claude Code and Cursor can run tests, update documentation, and manage mocks from the terminal. Learn more in What is Apidog MCP Server?.

Migrate from Insomnia in one import

Apidog imports Insomnia collections and environments directly.

Use this migration workflow:

1. Export your workspace from Insomnia.
2. Import the exported file into Apidog.
3. Verify imported requests, folders, environments, and variables.
4. Run existing requests to confirm the migration.
5. Generate an OpenAPI specification from the imported requests.
6. Use that specification to generate docs, mocks, and tests.

After importing, generate a spec from the requests to start a design-first workflow.

Move from a collection to a full API workflow in one day

Here is a practical first-day rollout for a team moving from Insomnia.

Morning: import and verify requests

Export the Insomnia workspace and import it into Apidog. Collections, folders, environments, and variables carry over. Run representative requests immediately so developers can continue debugging while the rest of the workflow is configured.

Mid-morning: generate an OpenAPI spec

Generate an OpenAPI specification from imported requests. This creates a structured API contract instead of leaving the project as a set of saved request definitions.

Use the generated spec as the source of truth for new endpoints and changes.

Midday: publish docs and enable mocks

With the spec in place:

1. Publish interactive documentation.
2. Add Markdown pages and versioning if needed.
3. Configure a custom domain for external consumers if required.
4. Let the mock engine generate responses from the JSON Schemas.

Frontend developers can call mock endpoints before the backend implementation is complete, without hand-authoring a separate mock service.

Afternoon: add one CI test scenario

Start with a high-value workflow, such as:

1. Authenticate.
2. Create a resource.
3. Validate the response.
4. Retrieve or update the resource.
5. Clean up test data.

Build that sequence as a visual scenario. Add assertions and pass values from one response into later requests. Run it locally first, then connect the same scenario to GitHub Actions, GitLab CI, or Jenkins.

By the end of the day, one API spec can drive requests, documentation, mocks, and a real CI test.

inso vs. apidog-cli in CI

Both platforms provide a CLI, but they automate different scopes of work.

Insomnia’s inso CLI runs collections and lints OpenAPI specifications in CI. That supports request replay and contract checks. For a detailed comparison, see the best inso alternatives.

apidog-cli extends automation beyond collection runs:

• Execute complete visual test scenarios with assertions, dynamic variables, and data passing between steps.
• Generate an HTML report for every run.
• Schedule suites without creating a separate CI job.
• Run tests through a self-hosted runner inside your own network.
• Install an agent skill with npx apidog-cli install-skill so Claude Code, Cursor, or Codex can run tests, update docs, and manage mocks from the terminal.

In short: inso automates request execution, while apidog-cli automates a broader API testing workflow. See how to manage APIs with the Apidog CLI for the command surface.

Team and enterprise workflow support

Apidog’s free plan supports four users, compared with Insomnia’s three. Paid plans start at $9 per user per month, compared with $12 per user per month for Insomnia.

For organizations with additional access and compliance requirements, Apidog includes:

• SSO with Okta and Microsoft Entra ID
• SCIM provisioning
• Role-based access control at the project level
• Apidog Europe, a GDPR-compliant deployment with data hosted in AWS Ireland and Germany
• A self-hosted runner for keeping test traffic inside your network
• Offline Space for projects that must stay on a developer’s machine

According to G2, users rank Apidog #1 for ease of use, with a 9.4 usability score and a 4.8 out of 5 overall rating.

When Insomnia is still enough

Insomnia remains a reasonable option if you are a solo developer who only needs to send and debug requests. Local Vault supports local-only work, and Git-based storage works well for teams committed to a spec-in-repository model.

Consider switching when your workflow needs more than debugging:

• Published API documentation
• Mock endpoints for frontend development
• Automated multi-step tests
• CI reporting
• Shared API lifecycle management

At that point, using a standalone client usually means introducing and maintaining more tools. That is when browser-based and single-purpose API clients stop scaling.

Frequently asked questions

How do I migrate from Insomnia to Apidog?

Export your Insomnia data, then import it into Apidog. Collections, folders, environments, and variables carry over. After importing, you can generate an OpenAPI specification from the requests.

Does Apidog have a free plan for teams?

Yes. Apidog supports up to four users on its free plan, with unlimited APIs, requests, and test runs. Insomnia’s free tier supports three users.

Can Apidog keep API data local like Insomnia’s Local Vault?

Yes. Apidog’s Offline Space keeps sensitive projects on your machine. Choose local storage for sensitive projects and shared workspaces for collaborative projects.

Does Apidog work in CI/CD pipelines?

Yes. The Apidog CLI runs test scenarios in Jenkins, GitLab CI, and GitHub Actions. It also provides HTML reports, scheduled runs, and a self-hosted runner. See the overview of the Insomnia API and its best alternative for more on the CLI differences.

Is my data safe during migration?

The import reads a file exported locally from Insomnia; it does not pull data from Kong’s cloud. After import, choose storage per project: keep sensitive APIs in Offline Space or use shared workspaces for team collaboration.

Does Apidog support gRPC and GraphQL like Insomnia?

Yes. Apidog supports HTTP, GraphQL, WebSocket, SSE, and gRPC, plus SOAP. It also includes pre-request and post-request scripts, response validation, and database connections.

Test it against your real workflow

Download Apidog, import an Insomnia workspace, and rebuild one complete flow:

1. Debug an endpoint.
2. Publish its documentation.
3. Generate a mock response.
4. Add an automated test.
5. Run that test in CI.

If that workflow works in one tool instead of several, the migration decision becomes straightforward. See the full Apidog vs. Insomnia comparison.
