Products that do what Surfer Protocol – Export and build applications with your personal data does
Hey everyone, we built a local-first, open-source framework to allows you to export and build applications with your personal data. This August, we built a digital footprint exporter (https://news.ycombinator.com/item?id=41325719) that allowed people to get back their personal data, but there was no way to interact with it. So we added a python package, improved the reliability of the exporting, and implemented a unified JSON structure across platforms. How it works: - Electron’s built-in webview element is used to navigate to the platform’s website and the user can connect…

I've been working on an MMORPG that is now in alpha as a solo developer. Here are the major open source technologies that I use: Blender - 3D modeling software for creating the overall environment and every game object. I've gotten a lot of CC and Public Domain assets from https://poly.pizza GLTF - I export assets from blender to the GLTF asset format JSON - I write a JSON config for every game object that describes things like its name, its interactions, its collisions, etc. Node.js exporter - I iterate over the environment and every asset to create a scene hierarchy. I use…

Hi guys, I've created an open source web builder framework (https://grapesjs.com) years ago, which I'm still maintaining, and now I'm excited to publish a side project based on it, Grapedrop (https://grapedrop.com). It's a simple web page builder which allows you to design and publish your web pages very quickly. The project is still in beta with a lot of stuff to improve but I'd really like to share it and hear what people think about it and maybe also get some constructive feedback.

Hello HN! The day has finally come to stop adding features and start sharing what I've been building the last 5-6 months. It's a bit of CrewAI, OpenDevon, LangFuse/Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code. I began experimenting with automating a simple Jira request from the engineering team to add an index to one of our Google Spanner databases (for context I'm the…

Hey HN, I'm excited to share Orbital, a new approach for unifying APIs and Data sources! Rather than relying on glue code to bridge endpoints, Orbital leverages annotations in schemas & API specs to build the integration dynamically. The traditional method of crafting glue code often becomes repetitive and burdensome to maintain in the long run. With Orbital, developers embed tags to their existing API specs (OAP, Protobuf, etc), indicating where data can be sourced, and publish these specs to Orbital (which runs self-hosted). Consumers query these tags with our TaxiQL language, and Orbital…

Hi HN, We’re Alex and Kalan, the creators of Pontoon (https://github.com/pontoon-data/Pontoon). Pontoon is an open-source data export platform that makes it really easy to create data syncs and send data to your enterprise customers. Check out our demo here: https://app.storylane.io/share/onova7c23ai6 or try it out with docker: https://pontoon-data.github.io/Pontoon/getting-started/quick... While at our prior roles as data engineers, we’ve both felt the pain of data APIs. We either had to spend weeks building out data pipelines…

Hi there! I've been working with data in one form or another, professionally, for about 5 years. I've been thinking about my own personal data and how it's used for at least twice that long. I've been sort of building something in my head for a while that solves my own problem and, in the beginning of this year, I found the opportunity to spend some time building it out. I'll leave the detailed explanation to the blog post but, in short, I built what amounts to an API crawler combined with a data processor to help you download your personal data from 3rd party services and work with it using…

Hey HN! Over the past few weeks, I’ve been working on DataBridge, an open-source solution for data ingestion and querying across text, PDFs, images, and videos. In our latest update, we’ve added a fully local deployment option: - No internet required – Runs entirely offline. - Customizable Models – Supports any LLM and embedding model via Ollama (with options for any other private providers) - Extensibility – You can plug in your own models or tools easily. This local-first approach ensures better privacy, security, and flexibility, especially for teams dealing with sensitive data. You can…

Hey HN. I'm a developer and solopreneur. Few months ago I realized I was doing the same thing over and over again: set up onboarding flow, user authentication, payments, connect a DB... So I built ExpoShip for 3 reasons: 1. Save Time and focus on what matters: building a business. 2. Avoid headaches like setting up authentication or handling in-app payments. 3. Get profitable fast. I hope this boilerplate will be as helpful to you as it is for me. Would love your feedback. Rudolfs

Announcing: ADAPT Framework ALPHA release and demo ADAPT Framework is a developer toolkit for replacing a centralized web back end with a decentralized mesh of interconnected data nodes. ADAPT is an easy way to build non-custodial internet applications for document sharing, messaging, credential management, medical data sharing, and other similar use cases. ADAPT enables developers to create data nodes that work identically on the front end and server side. All business logic that was traditionally placed into the back-end of an application can now be implemented by defining the behavior of…

Our new, free ros-tool capability makes it trivial to interact with ROS from the web. It provides a React API for subscribing and publish to topics and for placing service calls. It works with both ROS 1 and 2, and unlike rosbridge, it caches all data in the cloud, which means your UIs will work even when your robot is offline (just showing the latest data). Since all data is synced via the cloud, it is also much easier and more efficient to aggregate data from multiple robots, e.g., for showing your fleet on a map. Demo: https://www.youtube.com/watch?v=OgNdGvwYSiI

Hey HN! First post btw I want to share a product we are developing right now. It's a thing to gather your data from LinkedIn, GitHub, StackOverflow (and a couple more things in the future) and we obviously use LLMs under the hood :D So the idea of using it is that you don't need to share 69 links and docs and can use one link (or download PDF) now. When you connect all the stuff you will see your profile with a radar chart, which represents your "domains". The next thing will be a section with ai-generated-summary-bio + section with things you're open to. Then a section with work experience…

For a while, I've struggled to really get into the Mobile ecosystem. With the duopology that Google (Android) and Apple (iOS) hold on the mobile ecosystem, it's very difficult for developers to build and maintain decent mobile apps, especially when you're a solo developer and UI/UX isn't exactly you're fore anyway. So I built (after some experiments with a friend @xuu) a little Go application framework that combines HTMX, DaisyUI/TailwindCSS and Service Workers with a little hack that works remarkably well that I've been able to build 3 quite nicely polished mobile apps (PWAs you…

Recently I'm working on CopyUI which is an extension to copy UI element from websites and export html(or jsx) and css(or tailwind). I'm building this tool in order to create better landing pages because I'm really not good at layout and colors. So I hope to learn from others' design and innovate later, not to simply replicate.

Demo starts at 50m into the video. This was a bit terrifying to record because 2am the previous night everything was totally broken after a major refactor (so that we could add external LLM support as well as local GPUs). But pressure can be a useful force :-D We start with a stack deployed on my laptop without a GPU, pointing to together.ai so we can run open source LLMs easily without having to have access to a GPU. We show simple inference through the ChatGPT-like web interface (with users, sessions etc) and then simple drag'n'drop RAG. Then we show some helix apps defined as yaml: Marvin…

I’m Michał, and I’d like to share with you the journey I went through with my wife and how, thanks to her, we built our first SaaS, PDFBolt (https://pdfbolt.com). I’ve been a developer for over 10 years. In 2020, I decided to build a side project to learn all aspects of app development—deployment, authentication, payments, frontend, landing pages, etc. While looking for project ideas, I came across the Indie Hackers community, where I found a simple HTML to PDF API project. The creator mentioned a lot of interest in it and that it was generating revenue. I thought I’d build…

Hi HN! I recently open-sourced a project I’ve been working on over my winter break: a Solidity web framework you can use to write web apps in Solidity (and more generally, a proof-of-concept implementation of an arbitrary network protocol over Ethereum). Here’s a demo web app on the Optimism Goerli testnet: http://simple.fallback.natecation.xyz/ Running this Solidity code: https://github.com/nathanhleung/fallback/blob/main/src/examp... There’s a lightweight TCP server script that’s listening on the demo app domain that forwards requests…

We built Glue4 to scratch our own itch: whenever we start building an app, there’s all these different layers that need to be pieced together with subtle gotchas (auth, backend, DB, where to host, etc). The vast majority of the apps we build don’t really need anything beyond state persistence and authentication. And that’s what Glue4 abstracts away: having to host our own backend, pick our own DB, figure out the querying language/ORM and then host & maintain them all somewhere “in the cloud”. All you need to do is run a single npm install command and you get Auth + state persistence in…

Hi HN, Alexey from Chainstack here. We built Chainstack Self-Hosted to package everything we’ve learned from 8+ years of running blockchain nodes into a single control panel. The goal we’re building this product around is to make blockchain infrastructure boring to operate. The software is free to install. You only pay for the infrastructure you run it on. The quickest way to get hands-on with it is through the Vultr Marketplace or one of the other providers listed in the docs. The current release supports Ethereum Mainnet, Sepolia, and Hoodi with Reth + Prysm full nodes. We’ll be adding…
