Apidog▲570Development 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 This fragmented approach leads to outdated API specs and chaotic collaboration.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! I'm Greg and I've been working on Yaak for just over a year. I usually describe it as a Postman alternative since most developers are familiar with that, but it's targeted more toward users that just want an API client (no mocking, testing, spec design, etc). Having also created Insomnia for a similar purpose, I never thought I'd build another API client again. But, after selling Insomnia in 2019 and watching it expand into the broader feature set of Postman, I was left wanting a simpler tool again. Yaak was my answer to that. It's hard to describe how it's better than the 100 other…

In this release I have concentrated on user experience: - Full support of shortcuts - Reworked collections management - Notifications - Improved UX gRPC clients I’ve worked with had drawbacks and didn’t fit my use-case in a way I was expecting, since I’ve started working with gRPC 3+ years ago. Since then, I wanted a tool that fits any need in gRPC world. This is why I created ezy. Compared to Insomnia and Postman, ezy offers better streams support, allows you to use Server-Side and Mutual TLS with custom TLS certificates, works with gRPC-Web and has a more slick UI/UX. If you are…

Hi HN,<p>In my spare time (evenings and weekends) I've built 3 products which have been relatively successful even with little advertising (only google ads budgeted at $30 per day). The latest one is WcfStorm.Rest; which is a REST service test client. I built it because I found that the current tools did not have the features I wanted such as, intellisense when working with HTTP headers, syntax highlighting for JSON messages, etc.<p>I'm continually trying to improve these products and would very much love get your feedback. Every suggestion is welcome!<p>(My apologies…

Hey everyone, I've been working on publishing Lama2, a Plain-Text Powered REST API Client for Teams, for the past few months. Initial work on Lama2 started after my dissatisfaction with existing tools such as Postman/Insomnia. I wanted a text-powered and git-friendly system with a lightweight GUI layer on top so that I could onboard beginners/newcomers quickly into my team while also maintaining control over data. Today, we use Lama2 extensively internal to Hexmos; almost every internal code review tends to have a `.l2` API file attached now. It has worked great for us. More about…

Hi HN, I built ClientDock - a client portal for service providers to manage communications and files without email chaos. Background: After losing a critical client deliverable in a 200+ email thread, I decided to build a better solution. Most "client portals" are bloated project management tools. I wanted something focused on one thing: making client communication effortless. Technical Details: - Built with Next.js 15 (App Router) - Deployed on Cloudflare Workers using OpenNext adapter - Cloudflare D1 (SQLite at the edge) for data - NextAuth v5 for authentication - Drizzle ORM for type-safe…
