About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

Keploy is a testing platform that records API calls, database queries, and streaming interactions at the network layer using eBPF-style instrumentation, then replays them as test cases and data mocks with minimal application-code changes.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Generate tests and mocks from application traffic

keploy record captures runtime interactions so flows can later be replayed as regression tests.

Sources: [2]

Apply integration testing across languages without SDK changes

Network-layer capture reduces dependence on language-specific instrumentation and can be introduced around existing applications.

Sources: [2][3]

For converting real API traffic into regression-test assets

It fits backend/API teams that want to preserve realistic integration flows without manually recreating every test fixture.

Verify feature boundaries between the OSS binary and Community Edition

Current source messaging says the Community Edition adds protocols, AI test generation, sandbox replay, and MCP. Confirm the distribution required for your use case.

Supplemental curator note

Keploy's distinctive approach is to capture network interactions without requiring SDK changes in application code, then turn those interactions into tests and mocks. Current source messaging distinguishes the OSS binary from a free Community Edition that adds protocols plus AI test generation, sandbox replay, and MCP, so verify which distribution contains the capabilities you need.
