Show HN: DataSheetGrid, an Airtable-like React component
I've built and have been maintaining a React component that renders an Airtable / Notion-like component for a few years.<p>This can be seen as an <input/> where the value is an array of objects.
You can then specify any number of columns that are each responsible for rendering an input for a specific key.<p>The component handles all accessibility features like keyboard navigation, adding / removing rows, context menu, virtualization...<p>If you ever need your users to input long lists of data, this might be a good way to render the form!

Show HN: I spent 6 months building a C debugger as a 17-year-old
Hey HN my name is Thassilo, I'm a student and passionate programmer from Germany.<p>I want to showcase Spray, a small C debugger I've been working on for a few months now. Spray has a very simple and approachable interface. Its feature set is limited at this point, but it's already enough to tackle some basic problems. I stared to work on Spray because I was curious about how debuggers work. I am also trying to design Spray in such a way that it's easy to grasp and has a small mental overhead.<p>I'd love to get your feedback on Spray.<p>Email: d4kd (at) proton (dot) me<p>PS: I'm generally interested compilers and language tool chains, and I'm looking for similar-minded people to work and collaborate with. I have a few similar projects on my GitHub: <a href="https://github.com/d4ckard?tab=repositories">https://github.com/d4ckard?tab=repositories</a>. If you find Spray interesting, you might enjoy playing around with them too.

Show HN: Cost&Time AI Estimator for MVP and Full Product. Seeking Your Feedback
Hi HN community,<p>We're developing a free tool that aims to help founders and product teams estimate the costs of developing an MVP versus a full-scale product.<p>Here's the gist:
1. You input a description of your idea into our AI Estimator.
2. It provides you with two estimates: one for an MVP and another for a complete product.<p>We're sharing it here because we value the critical and insightful feedback that the HN community is known for. The tool is in its early stages, and we're looking to refine its accuracy and user experience.<p>If you have a moment, please try it out: <a href="https://www.allcancode.com/time-to-market" rel="nofollow noreferrer">https://www.allcancode.com/time-to-market</a><p>We'd be grateful for any feedback on the following:
1. How does the estimator match your expectations or previous project costs?
2. Is the user interface intuitive enough?
3. What additional features would you want in such a tool?<p>Feel free to DM me or comment below with your thoughts. Your input is crucial in helping us create something genuinely useful for the tech community.

Show HN: Telophase – Open-Source AWS Control Tower
Hey HN – We’re Danny and Ethan from Telophase (<a href="https://telophase.dev">https://telophase.dev</a>). We’re building automation to isolate cloud environments by tenant or team. You can think of us as an Open-Source AWS Control Tower[1].<p>Our CLI is a drop-in tool to manage multi-account AWS setups. To start, we support AWS Account Factory and landing zones defined in AWS CDK. We plan to support multi-project GCP and multi-subscription Azure setups soon!<p>Features:<p>1. Manage accounts in code.<p>2. Provision accounts and their infrastructure with a single command, `telophase deploy`.<p>3. Deploy to a subset of accounts using tags such as staging, prod-eu, prod-us, etc<p>4. Monitor concurrent CDK deploys with our TUI<p>We decided to build Telophase after managing hundreds of accounts with Control Tower. We found it inflexible and required more integration work than we expected. Check out the readme for more:<p><a href="https://github.com/Santiago-Labs/telophasecli">https://github.com/Santiago-Labs/telophasecli</a><p>[1] <a href="https://aws.amazon.com/controltower/" rel="nofollow noreferrer">https://aws.amazon.com/controltower/</a>

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!
