   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 This fragmented approach leads to outdated API specs and chaotic collaboration.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.

   DontBeEvil.rip: Search, for developers (API, expressions, CLI)▲269

   I'd like to invite everyone to try out DontBeEvil.rip, an experimental search engine for developers. tl;dr $ alias rip="curl -G -H 'Accept: text/plain' --url https://dontbeevil.rip/search --data-urlencode " $ rip 'q=Heartbleed bug' DontBeEvil.rip is a year long experiment to see if a small team can build a developer-focused search engine that is self-sustaining on $10 monthly subscriptions. It works by only indexing high-quality resources that are relevant to developers. You won't get useless listicles because we'll never crawl them. Relevant urls are harvested from HN,…

   Buildstash▲168

   Hey HN! We just launched open sign up on Buildstash. It's a platform for managing and sharing software binaries. I'd worked across game dev, mobile apps, and agencies - and found every team had no real system for managing their built binaries. Often just dumped in a shared folder (if someone remembered!). No system for versioning, keeping track of who'd signed off what when, or what exact build had gone to a client, etc. Existing tools out there for managing build artifacts are really focused on package repository management. But miss all the other types of software not being deployed that…

   An open source performance monitoring tool▲135

   Hey HN. We’re Jay and Vadim from Highlight.io (https://highlight.io). We’re building an open source [1] monitoring platform for web applications. Today we’re excited to be sharing a performance tool we’ve been working on, which helps you inspect the latency of code execution from the client to the server. As engineers at past startups, we often had to debug slow queries, poor load times, inconsistent errors, etc... While tools like Jaegar [2] helped us inspect server-side performance, we had no way to tie user events to the traces we were inspecting. In other words, although we had…

    I built a tool to get instant test results▲96

    I got sick of the old software development loop: Change code -> Run tests -> wait -> wait some more -> look at failures. I decided to build a tool that will enable you to: Change code -> look at failures. No wait time, no explicit test running. Under the hood: - Runs the whole test suite and collects code coverage per test. - For each auto file save, analyzes the changes on the tests. - Runs changed tests in the background. - Display results, the loop time from change to test results is approx 250ms. Instead of: code -> alt+tab -> arrow up -> rerun all the tests -> wait ... -> test results…

    Mocktail – Free, open-source mock API server with a built-in dashboard▲25

    Hi HN, I built the first version of Mocktail years ago. I recently came back to the project, and after a pretty substantial rebuild, v4 is now out. Mocktail is a free and open-source, self-hosted mock API server with a built-in dashboard and database, packaged as a single ~25 MB binary. You can run it locally or on your own infrastructure — no account or hosted service required. You can define endpoints and responses, generate realistic data per request, customize headers, status codes and latency, and inspect incoming requests in real time. With v4, I also added MCP support, so coding…

    Spin up populated test databases in seconds▲70

    We are building Tonic Ephemeral - a purpose built test database that is easy and fast to spin up (or down) based on your dev and test requirements. As engineers who worked on data at Palantir and Tableau, we've seen developers struggle to get isolated test databases when needed. We faced the same problem while we were building our core product at Tonic. Based on this, we decided to build something for ourselves and then realized some of our customers loved it too. Today, we are sharing Tonic Ephemeral with the world. Briefly, Tonic Ephemeral manages test data infrastructure. In my…

    Tesmon Platform == Postman + Cypress + RestAssured + Database + More▲14

    I'm Nagaraj, the founder of Tesmon. Having been both a developer and an engineering leader, from big tech companies to startups, I've personally encountered the challenges of integration testing. It's often so cumbersome that we resort to manual testing. The world of testing is fragmented across multiple frameworks and platforms like Postman, RestAssured, pytest, Selenium, Cypress, Testim, and various custom in-house code using open source frameworks. Building and maintaining this testing infrastructure is not only time-consuming but can be a real pain. Our mission is to revolutionize…

    Trying to fix the web scraping industry's benchmark problem▲18

    We've been trying to evaluate web scraping companies, but when you look at their benchmarks, you can't verify anything, and they mostly exist to prove the company is successful. They put somewhere between 98% and 100% because they pick their own urls, define success their own way, and don't publish the harness. We also saw companies like scrapfly astroturf websites like scrapeway and call them independent. So, we built an open source benchmark that we want to represent the frontier of web data. We're trying to look across all major anti-bot providers and industries, to build a comprehensive…

    Mock Studio▲3

    Hi HN, I built this after using Requestly, Mokku, Mockiato, Tweak, and Mockoon. Each one either paywalled the features I actually needed, required a separate server running on my machine, or just didn't fit the way I work. The browser is already open. DevTools is already open. I wanted the mocking to live there too, not in a separate app I have to remember to start. So roughly a month ago, I started building my own tools. It intercepts network requests at the browser level and lets you swap the response, status code, headers, body without touching your code or spinning up anything.…
