24 alternatives to fallback() – write web apps in Solidity and serve HTTP over Ethereum
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…
Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. fallback() – write web apps in Solidity and serve HTTP over Ethereum launched in 2022; newer entries below may have overtaken it.

Hey HN! I’ve written a bunch of WebSocket servers over the years to do simple things like state synchronization, WebRTC signaling, and notifying a client when a backend job was run. I realized that if I had a simple way to create a private, temporary, mini-redis that the client could talk to directly, it would save a lot of time. So we created DriftDB. In addition to the open source server that you can run yourself, we also provide https://jamsocket.live where you can use an instance we host on Cloudflare’s edge (~13ms round trip latency from my home in NY). You may have seen my…

Hi everyone, I recently published a small open-source project. It’s a minimal network packet analyzer written in Go — designed more like a learning toy than a replacement for Wireshark. It currently supports parsing basic protocols like TLS, DNS, and HTTP, and includes a tiny fuzzing engine to test payload responses. You can inspect raw packet content directly from the terminal. The output is colored for readability, and the code structure is kept simple and clear. The entire program is very small — just about 400 lines of Go code. I know it’s not anywhere near Wireshark’s level, and I still…

I've been trying to write my "go on rails" framework for years. I never quite got it like I wanted. There is gin and echo and all sorts of other frameworks and patterns but I finally found something I really like: /foo/ /foo/bar/ /foo/bar/more/ That's it. Just three levels and all my controllers get passed in what's between the / with var names first, second, third. In order to really make sure this framework could build something real I made a Hacker News clone. RemoteRenters.com is a HN just for articles about the remote work revolution…

Hey everyone! Over the past two years I threw myself back into full-time engineering with a simple goal: write code that gives back to the community. After a lot of late-night FOMO (“AI will do it all for us, right?”) and some painful production incidents, I finally turned my weekend project into an open-source library. [ What is Solidis? ] - Super-light (< 30 KB) RESP2/RESP3 client with zero runtime deps and first-class ESM/CJS support. - Fully tree-shakable – import only the commands you need. - Written with SOLID principles & full TypeScript typings for every command. - Designed…

Hey! I'm a solo developer having fun learning Go. I have a side hustle and wanted to implement currency localization. I could use existing IP databases, but hosting on serverless is slow. So I built my own. I was surprised how fun it can be to use Go, and it's fast. Thankfully, Go's speed makes up for my dodgy code. Anyway, I'd love to get some feedback on my website/API. After a few weeks of testing and losing money on ads, I'm confident it's very reliable. This isn't a promo. It's basicly free (30k lookups/month), so there's no need to pay. Any advice or tips on how to grow and…

Hi guys, I've written the first proof-of-mistake crypto token on top of Ethereum. You can see it at http://www.lostethereum.com/ It's basically a proof-of-burn substitute for users who mistakenly sent to the wrong address. It requires a web3 enabled browser, i.e chome with MetaMask, Parity, Mist, etc. This let's the web interface seamlessly interact with the Ethereum network. Let me know what you guys think.

Hi! I’ve always wanted a simple way to throw my Python projects online. Just to try things out, share them, or test a webhook with a real endpoint. But every time I hit the same wall: Buy a server, Set up HTTPS, Configure DNS, Get a domain. Write boilerplate to glue it together. It always felt like too much for something so small that I wanted to test. So Ive been hacking on Thread4 (currently in alpha): a tiny platform where you can write a Python function and go live instantly at yourname.thread4.eu. It’s not for production use, just quick testing, experimenting, or sharing your idea…

wsgrok▲7I built it for myself because ngrok didn't let me add one more domain unless I paid $12 more. I probably should've looked for alternatives before building my own, but my grudge got in the way . Once I started, I wanted to make it better than the other options. Silly, I know. No one probably cares. I plan to open source it sometime next year because I’ve got other projects to finish first. It's free until I deplete my cloud credits, then it will switch to a tier-based model with a free option.

I've been having a blast making multiple mini apps that run in the browser. I've been trying to see how far I can go without having a backend and relying on other services. I wrote these for fun and wanted to know what folks think.

Hi guys, It is no secret that I'm pretty tired of the political infighting around Bitcoin. The environment got so toxic that I stopped most of my Bitcoin-centric development to focus on other projects. I'm pretty sure there are many developers who have felt the same way, and the result has been an explosion in alternative coins and technologies as developer resources have gone elsewhere. So, I started a simple experiment. What if we got rid of developers entirely, and just replicated and adapted the deflationary structure of Bitcoin on Ethereum. We could model the entire process as an…
