In their own words
BitDive
BitDive is a freemium API, web, and self-hosted tool for Java and Kotlin teams that want to verify code changes against recorded service behavior. Its agent captures method calls, SQL queries, HTTP requests, Kafka messages, JVM metrics, and exception traces, then compares behavior before and after changes to reveal SQL drift, extra HTTP calls, and performance regressions. Recorded executions become replayable JUnit 5 tests that run with standard Maven or Gradle tooling. The agent supports Java 8 through 21 and captures bytecode behavior without source changes. BitDive exposes runtime context and trace operations through MCP for Cursor, Windsurf, and Claude. It 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. Security details specify TLS 1.3 in transit, AES-256 at rest, and in-JVM masking of sensitive fields. Developer Use costs nothing; Company Rollout pricing is custom.
Specmatic
Specmatic turns API specifications into executable contracts for designing, building, and governing APIs. Its suite includes Genie, which generates API specifications from plain English; Studio for visual API workflows and contract testing; and Insights for API governance and analytics. Listed formats include OpenAPI, AsyncAPI, Avro, GraphQL SDL, Protobuf, WSDL, and Arazzo. Protocols include HTTP/REST, Kafka, gRPC, GraphQL, Google Pub/Sub, JMS, MQTT, RabbitMQ, SOAP, WebSocket, and MCP. The free Open Source plan includes contract and API resilience testing, service virtualization, backward compatibility testing, a proxy server, and a specification coverage report. Enterprise adds Studio and Insights, available as SaaS or on-premise, alongside additional protocol and workflow capabilities. The software supports Linux, macOS, Windows, and self-hosted environments, with installation options including shell and PowerShell scripts, npm, and pip. A free plan is available; the pricing note lists paid access from $10/user/mo (annual).
