Keploy vs Testsigma
Keploy auto-generates API tests from real production traffic using eBPF with zero code changes. Testsigma is an AI-powered, low-code test automation platform for web, mobile, and API testing using natural language test steps. Keploy suits teams wanting zero-effort API test generation; Testsigma suits QA teams wanting low-code test creation with AI-assisted maintenance.
How They Work Differently
Architectural differences that affect your team's workflow, cost, and velocity.
KeployKeploy uses eBPF to record real API calls and responses from your running application, then replays them as regression tests. It auto-generates mocks for downstream dependencies and handles non-deterministic data automatically. No test scripts — natural language or otherwise.
TestsigmaTestsigma lets teams write tests using natural language (NLP) steps in a cloud-based IDE. For API testing, it provides a REST API testing module where testers define requests, assertions, and data-driven scenarios without coding. AI assists with test maintenance by auto-healing broken element locators and suggesting fixes.

TestsigmaWhen to Use Each Tool
Specific scenarios where each tool delivers the most value for your engineering team.
Keploy is the better fit when you need to...
- Want fully automatic test generation from traffic with zero authoring
- Need automatic mock generation for databases and downstream services
- Prefer CLI-based, developer-first tooling over cloud-based IDEs
- Do not need web or mobile UI testing in the same platform
- Want open-source, self-hosted tooling without cloud dependency
Testsigma is the better fit when you need to...
- Need a low-code platform accessible to manual QA testers
- Want AI-assisted test maintenance with auto-healing capabilities
- Need web, mobile, and API testing in one unified cloud platform
- Prefer natural language test steps over code or traffic capture
- Want built-in test management, reporting, and collaboration features
Real-World Scenarios
How each tool handles the challenges your team actually faces.
Your team ships 50 PRs/week and needs regression coverage
Keploy captures traffic and generates regression tests automatically. No one writes NLP steps or maintains test scripts. Coverage grows with real usage.
Testsigma's AI helps maintain tests when UI changes, but someone still needs to author the initial test steps. At 50 PRs/week, AI maintenance helps but initial authoring takes time.
You're migrating from monolith to microservices
Keploy records monolith traffic, auto-generates dependency mocks, and verifies new microservices produce equivalent responses. No manual test authoring.
Testsigma can test new microservice APIs through its REST module. You write NLP test steps for each service. AI helps maintain tests as APIs evolve during migration.
New developer onboarding — writing first tests
New developers run the app with Keploy and get production-based tests immediately. No NLP syntax or cloud platform to learn.
Testsigma's natural language approach is very accessible. New QA team members can write test steps in plain English without learning a programming language or test framework.
FAQs
Testsigma uses AI for test maintenance — auto-healing locators, suggesting fixes for broken steps. Keploy uses a fundamentally different approach — capturing real traffic and replaying it. Keploy eliminates test authoring; Testsigma makes test authoring easier.
Testsigma has a community edition that is open source. The full cloud platform with AI features is proprietary with per-user pricing. Keploy is fully open source under Apache 2.0.
Keploy is developer-first — CLI-based, no GUI required. Testsigma is QA-first — natural language steps in a visual cloud IDE. Your choice depends on who is writing and maintaining tests.
Testsigma can import API specs and suggest test steps, but tests still require human authoring and curation. Keploy generates complete test suites from real traffic with no human authoring.
Keploy tests auto-update when you re-record traffic. Testsigma uses AI to detect and fix broken tests. Both reduce maintenance burden but through different mechanisms.
Looking for a Testsigma Alternative?
Engineering teams evaluating Testsigma alternatives often compare it with Keploy for API testing and regression coverage. Keploy captures real production traffic via eBPF and auto-generates tests with dependency mocks — requiring zero code changes. If you're considering switching from Testsigma or comparing Testsigma and Keploy side by side, the key differences come down to how tests are generated (traffic-based vs manual), how dependencies are mocked (automatic vs configured), and what infrastructure changes are needed (none vs SDK/sidecar/containers).
