Kusho's AI test automation generates production-ready API and UI test suites in minutes with 100% backend coverage and built-in security testing, free to start.
Kusho is an AI test automation platform that generates production-ready API and UI test suites from OpenAPI specs and Postman collections in minutes, delivering 100% backend coverage including edge cases and security tests. Teams report 80% reduction in manual testing time, with the system auto-healing broken tests as APIs evolve.
Developer Edition (Free): $0/mo, no credit card required, up to 50 users, community support, cloud only. Enterprise: custom pricing based on API endpoints tested (500-10,000+), UI workflows (250-1,000+), monthly test execution volume (50K-5M+), and team size (15-500+ seats). Contact sales for quote.
Kusho is an AI test automation platform founded in 2023 by Abhishek Saikia and Sourabh Gawande, headquartered in San Francisco. It is a generative AI quality engineering platform that generates, runs, and maintains API and UI test suites for API-driven and microservices architectures without manual scripting. Kusho takes an OpenAPI spec, a Postman collection, a cURL command, or a plain-English description and generates a complete test suite covering API, UI, end-to-end, and security testing. When the underlying API changes, Kusho detects the diff and updates the affected tests automatically, which the company calls auto-healing. The company raised a $600K pre-seed round led by Antler in February 2024, with participation from Blume Ventures and Upsparks Capital. Kusho is aimed at backend developers, QA engineers, and DevOps teams working on API-first products.
Kusho offers a Developer Edition at $0 per month with no credit card required, designed for individual developers and teams up to 50 people evaluating the platform. The Enterprise tier uses custom pricing based on the number of API endpoints tested (500 to 10,000+), UI workflows, monthly test execution volume (50K to 5M+ runs), and team size (15 to 500+ seats). Enterprise pricing requires contacting Kusho sales for a quote; Capterra lists a starting reference around $5,000 per month for Enterprise, but actual cost varies by usage. There is no published self-serve monthly rate for Enterprise on Kusho marketing pages.
Kusho's core differentiator is auto-healing: when a team's API contract changes, Kusho automatically detects the drift and updates the relevant tests itself, rather than leaving teams with broken tests after every deploy. Unlike Postman, which is primarily an API collaboration and documentation tool, Kusho can take a Postman collection or OpenAPI spec and generate a complete, ready-to-run test suite covering API, UI, end-to-end, and security testing in one pass. Kusho also assigns AI-computed risk scores to each release based on what changed and what failed, helping teams decide whether a release is safe to ship. Teams report an 80% reduction in manual testing time and 100% backend test coverage including edge cases, according to Kusho's published case data. The combination of natural-language test generation, contract drift detection, and CI/CD-native execution across GitHub Actions, GitLab, Bitbucket, and Jenkins is the core bundle that sets it apart from single-purpose API tools.
Postman is built for API design, documentation, and manual exploration, and while it includes basic test scripting, it was not designed to generate and maintain a full automated regression suite on its own. Kusho is built specifically for automated test generation and maintenance: it can import an existing Postman collection or OpenAPI spec and turn it into a complete test suite covering API, UI, end-to-end, and security checks, then keep those tests updated as the API changes through contract drift detection. Kusho's blog frames the relationship as complementary rather than competitive, positioning Postman as the tool for exploring and documenting APIs and Kusho as the tool for continuous, self-maintaining test coverage. Teams that already use Postman for API collaboration can feed those collections directly into Kusho rather than rebuilding test suites from scratch, while teams that want regression tests to run automatically on every commit and update themselves need a dedicated tool like Kusho rather than relying on Postman's manual test scripts.
Yes. Kusho's Developer Edition is a permanent $0 per month plan, not a time-limited free trial. It requires no credit card and supports teams up to 50 people for API contract testing, UI testing, test generation and execution, and end-to-end workflow testing. The Developer Edition is intended for POC and evaluation work rather than production scale. Unlimited test runs, full CI/CD integration, security testing (OWASP), SSO/SAML, RBAC, on-premise deployment, and SOC2/ISO27001 certified data security are available on the Enterprise tier, which requires a custom quote based on API endpoints, test execution volume, and team size. Teams can start on the Developer Edition to evaluate whether Kusho AI-generated tests fit their workflow before moving to Enterprise for production deployments.
Kusho is best for backend developers, QA engineers, and DevOps teams working on API-first or microservices architectures who want test suites generated automatically from existing specs (OpenAPI, Postman, cURL) and kept up to date as the API evolves. Teams already running CI/CD pipelines on GitHub Actions, GitLab, Bitbucket, or Jenkins can plug Kusho's generated tests directly into existing workflows and get risk scores on each release. Kusho is less suited to frontend-only teams or non-technical users, since it is explicitly positioned for API-first and microservices environments rather than general UI testing on its own. Teams should also not treat Kusho as a full replacement for human testers: reviewers note that human expertise is still needed to design practical test cases and interpret results, and over-reliance on automation can miss complex edge cases that require domain judgment.
Yes, security testing is one of Kusho's core test types alongside API, UI, and end-to-end tests. Kusho scans APIs for vulnerabilities, misconfigurations, and access control risks as part of the same generated test suite that covers functional API behavior, rather than requiring a separate security testing tool. When the underlying API contract changes, Kusho's contract drift detection also re-evaluates and updates security tests so they continue to reflect the current API surface rather than testing against an outdated version. This is part of why Kusho reports 100% backend test coverage including edge cases and security tests in its published case studies. For teams that previously relied on manual security review or a separate penetration testing cycle for API endpoints, having access control and misconfiguration checks generated and maintained alongside functional tests reduces the number of separate tools needed in the testing pipeline.
Kusho's Enterprise tier is SOC2 and ISO27001 certified, meaning data handling on the Enterprise plan is audited against those security standards. The Developer Edition (free plan) does not carry those certifications, so teams with strict compliance requirements should move to Enterprise and verify the specifics of Kusho's data processing agreement before connecting production API specs. Kusho's general data licensing is proprietary. The company does not publish a public breakdown of model training practices on customer API data in its marketing pages, so teams handling regulated or sensitive data should request Kusho's current DPA and security documentation during the sales process to confirm data isolation, retention policies, and whether customer specs are used for model training.
