Show HN: Jwt.is – JSON Web Token Debugger
The team at Rownd is excited to announce <a href="https://jwt.is" rel="nofollow noreferrer">https://jwt.is</a>, an updated take on JSON Web Token debugging.<p>Like most developers, we've used jwt.io for years, but it lacks a number of useful features that would make it even more convenient. We're building on the shoulders of those who've come before us. :-)<p>In addition to the basic JWT decoding and signature verification, we've added things like:
- Verification using JWK endpoints
- Locally stored history of tokens and keys
- Verification for EdDSA signatures
- Detection of common token providers (e.g., Google, Apple, etc)
- Dark mode!<p>In the future, we plan to add features like offline mode and more granular token/key storage management so you can precisely control what sticks around.<p>Additionally, we've made this completely open source (MIT-licensed), so it's free to use and modify as you wish. And of course, contributions are always welcomed!<p>Let us know what you think!

Show HN: GPT-4V audit for your landing page
I got seriously fascinated by the new GPT-4 Vision API introduced on OpenAI DevDay, so I decided to build a UX Audit tool with it.<p>It's pretty simple to use - just go to <a href="https://uxaudit.vercel.app" rel="nofollow noreferrer">https://uxaudit.vercel.app</a> and enter your homepage or landing page URL.<p>I'm using urlbox to get a screenshot of your page, then I utilize GPT-4V to analyze the screenshot and find potential usability and conversion issues. It also suggests solutions and highlights the relevant problem areas in the screenshot (although the position is sometimes inaccurate).<p>Please let me know your thoughts and suggestions on how to improve it.

Show HN: Nango – Open unified API for product integrations
Today customers expect every SaaS product to integrate with the other tools they use. Nango is a tool for engineers at SaaS companies to help them ship integrations fast, without compromising on the integration’s depth and quality. It supports more than 100 APIs out of the box.<p>Other integration companies have focused on building a lot of pre-built integrations. These are fast to ship and low maintenance, but they limit how deeply you can integrate with the external APIs.<p>We take a different approach: we make it easier for developers to build and maintain product integrations in code. This lets you create exactly the integration your customers need without compromising on speed and maintainability, and without having to build complex infrastructure (OAuth, retries, rate-limit handling, change detection, monitoring & logging, alerting, etc.).<p>Our platform has two layers: (1) An API-agnostic infrastructure built with Temporal and Postgres, and (2) lambda function-like integrations written in typescript by any developer.<p>Integrations are rarely more than 50 lines of code (here is an example: <a href="https://bit.ly/nango-example" rel="nofollow noreferrer">https://bit.ly/nango-example</a>), thanks to the developer tooling we’ve built in: authentication, pagination, retries, change detection, rate-limit handling, monitoring, Slack alerts, etc.<p>We have pre-built integration templates you can clone and extend—or you can build entirely custom integrations. Your integrations live in your repo and are tested and deployed to Nango with a CLI.<p>In your product, you use a single API to interact with all your integrations. This lets you easily grow the available integrations with minimal code changes in your product.<p>As a community-driven project, anybody can contribute integration templates and APIs to the platform. In fact, more than 30% of the APIs we support today have been contributed by our community.<p>Nango grew out of a “universal OAuth” project called Pizzly and powers the integrations of 100+ SaaS products today. We have an active community of 800+ developers (<a href="https://nango.dev/slack">https://nango.dev/slack</a>).<p>All auth-related features are free forever, and we monetize with sync-related features. The entire code base and all integrations are source-available: <a href="https://github.com/NangoHQ/nango">https://github.com/NangoHQ/nango</a>.<p>We hope Nango can help connect all SaaS products together and look forward to your feedback!

Show HN: QBasic 4.5 on Android
My father, who hung up his coding hat in the '80s, recently entered the golden years of retirement.<p>One day, he mused about the simplicity and educational value of BASIC and wondered if there was a way to share its charm using today's technology.<p>Specifically, he was looking for an Android application that could run BASIC so he could "teach programming while drinking coffee with [his] friends".<p>Thus, BabaBASIC was born—a hat tip to 'Babá', the Greek term for "dad", and a reminder of who sparked this journey.<p>The first iteration of this was made over a 10-hour all-nighter using existing open-source libraries.<p>I ended up forking the BASIC-like implementation to make it more byte-for-byte compatible with QBasic 4.5, which is what my father used back in the 90s to teach me programming.<p>This is the first thing I have ever made of which he approves.

Show HN: Javaflame – Simple Flamegraph for your Java application
Javaflame will generate a flamegraph of your application function calls, including the argument values and the return of each function.<p>Check <a href="https://beothorn.github.io/javaflame" rel="nofollow noreferrer">https://beothorn.github.io/javaflame</a> to see an example.<p>There are already some tools that render flamegraphs for java, but they are focused on measuring performance or require some other process running along with the application. They also record function calls, but do not record the arguments or return values from those functions.<p>I needed instead something to help understand and debug my applications that was better than adding breakpoints and slowly step over every call.<p>This is a simple java agent that renders a flamegraph on a html file, no extra dependencies or other processes involved. All you need is an extra argument passed to the JVM on the command line pointing to the java agent.<p>It calls toString on every parameter and return value of every function that is included on the filter, so I wouldn't use this outside your dev machine.
