Instead of Keploy
Keploy alternatives
Keploy is suited to teams that want application traffic turned into repeatable tests and dependency sandboxes. It records requests and dependency calls without code changes, replays them with mocks in CI, and supports local, Kubernetes, and air-gapped enterprise deployments. Playground can generate API tests from OpenAPI or Postman inputs, while AI expands edge cases. Its browser extension captures XHR and fetch context, and the open-source core records and replays traffic locally. Protocol coverage includes HTTP, gRPC, GraphQL, Kafka, and several databases, with integrations for common CI systems.

Alternatives make sense when Keploy’s traffic-first workflow, plan limits, or pricing do not fit. Keploy has a free tier, Pro from $19/user/mo, and Enterprise pricing by discussion; Pro CI replay uses a Keploy API key. Compare whether you need specification-led design, a Git-native client, broad UI and performance testing, collaborative workspaces, or a lightweight command line. Also consider scripting, mock creation, protocol needs, deployment control, and the platforms your team already uses.
