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 This fragmented approach leads to outdated API specs and chaotic collaboration.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

We built SwiftAI, an open-source Swift library that lets you use Apple’s on-device LLMs when available (Apple opened access in June), and fall back to a cloud model when they aren’t available — all without duplicating code. SwiftAI gives you: - A single, model-agnostic API - An agent/tool loop - Strongly-typed structured outputs - Optional chat state Backstory: We started experimenting with Apple’s local models because they’re free (no API calls), private, and work offline. The problem: not all devices support them (older iPhones, Apple Intelligence disabled, low battery, etc.). That…

We’ve been working on Scout QA, a tool that uses AI to catch subtle bugs that usually slip past manual testing and reviews. Instead of focusing on test automation, Scout analyzes your app’s UI, flows, and logs to surface tiny inconsistencies — things like broken states, unclear error messages, or small regressions that humans might ignore because “it still works.” The goal isn’t to replace testers but to act like an extra pair of curious eyes — pointing out issues that affect real users’ experience. We’re exploring questions like: - How can an AI develop an intuition for “something feels…
