What BitDive is

BitDive captures runtime behavior from Java and Kotlin services and turns recorded executions into replayable JUnit 5 tests for checking code changes. Its agent records method calls, SQL queries, HTTP requests, Kafka messages, JVM metrics and exception traces. Comparing behavior before and after a change can reveal SQL drift, extra HTTP calls and performance regressions; generated tests run with standard Maven or Gradle tooling. The agent supports Java 8 through 21 and captures bytecode-level behavior without source-code changes. BitDive also exposes runtime context and trace operations through MCP for AI coding tools including Cursor, Windsurf and Claude. Its integrations page lists 49 supported technologies, including Spring Boot, PostgreSQL, MongoDB, Kafka, JUnit 5, Testcontainers and Maven. Deployment options include hosted SaaS, on-premise and air-gapped installations, as well as a one-command self-hosted setup. The security page specifies TLS 1.3 in transit, AES-256 at rest and in-JVM masking of sensitive fields before data leaves. Individual developer use costs nothing, but is provided without SLA commitments, indemnities or custom engineering work.

Who it suits

BitDive is aimed at modern JVM engineering teams that want to compare service behavior around code changes and generate replayable tests. Individual developers can use the free workflow, while company rollout includes organizational features and priority support at a custom price.
