    Apidog▲570

    Development teams often struggle with using multiple tools like Postman and Swagger for API design, development, and testing. This fragmented approach leads to outdated API specs and chaotic collaboration. So we built Apidog: a single, unified API platform for team collaboration. It has a beautiful interface that makes it easy to create API spec, generate request data from API spec, validate responses, create mock data, orchestrate test scenarios, and publish API documentation. Apidog = Postman + Swagger + Mock + JMeter.

    Hi HN, Mike and Warren here! We've been building HyperDX (hyperdx.io). HyperDX allows you to easily search and correlate logs, traces, metrics (alpha), and session replays all in one place. For example, if a user reports a bug “this button doesn't work," an engineer can play back what the user was doing in their browser and trace API calls back to the backend logs for that specific request, all from a single view. Github Repo: https://github.com/hyperdxio/hyperdx Coming from an observability nerd background, with Warren being SRE #1 at his last startup and me previously…

    We built Gonzo to make log analysis faster and friendlier in the terminal. Think of it like k9s for logs — a TUI that can ingest JSON, text, or OpenTelemetry (OTLP) logs, highlight and boil up patterns, and even run AI models locally or via API to summarize logs. We’re still iterating, so ideas and contributions are welcome!

    For the past few months we’ve been building a simple jest/typescript-based high-level language for writing and running integration tests. We're open-sourcing it now and are excited to share it with you: https://github.com/traceloop/jest-opentelemetry Why we built this: - There are many solid frameworks for FE / browser testing, but none with high-level constructs for testing BE flows - We were missing a way to validate side effects for complex backend systems, especially across async queueing systems Our beta version lets you send an API call to a system and…
