24 alternatives to CustomJS
Hello, as an Indie Hacker, I have built and successfully launched this SaaS software. Originally it was a plugin for Make.com but now it can also be used for many other user cases. It's a niche market but many users are enjoying it. Feel free to give me more feedback https://www.customjs.space

I spent a few hours last weekend testing whether AI can replace code by executing directly. Built a contact manager where every HTTP request goes to an LLM with three tools: database (SQLite), webResponse (HTML/JSON/JS), and updateMemory (feedback). No routes, no controllers, no business logic. The AI designs schemas on first request, generates UIs from paths alone, and evolves based on natural language feedback. It works—forms submit, data persists, APIs return JSON—but it's catastrophically slow (30-60s per request), absurdly expensive ($0.05/request), and has zero UI…

Indie Kit▲58I wanted to build simple apps to launch over the weekend. I was so frustrated implementing billing, stripe, auth, quota management, etc. I just gave up. So I made Indie Kit Login users, process payments, send emails at lightspeed. Spend your time building your startup, not integrating APIs. Indie Kit provides you with the boilerplate code you need to launch, FASTER THAN EVER.

I built µJS because I wanted AJAX navigation without the verbosity of HTMX or the overhead of Turbo. It intercepts links and form submissions, fetches pages via AJAX, and swaps fragments of the DOM. Single tag, one call to `mu.init()`. No build step, no dependencies. Key features: patch mode (update multiple fragments in one request), SSE support, DOM morphing via idiomorph, View Transitions, prefetch on hover, polling, and full HTTP verb support on any element. At ~5KB gzipped, it's smaller than HTMX (16KB) and Turbo (25KB), and works with any backend: PHP, Python, Go, Ruby, whatever.…

Nexty▲22The Next.js SaaS boilerplate market is saturated, but there's still room if you solve real developer pain points. I believe I've done exactly that – 70+ customers in just 90 days proves there's genuine demand for what Nexty offers. Hi, I'm Jude Wei, a software engineer obsessed with understanding what developers actually need. 90 days ago, I started building what I thought would be just another personal Next.js template. But as features evolved, I realized I was creating something that could genuinely help fellow developers ship faster. That's when Nexty.dev was born. Thanks to incredible…

Hey HN, I'm a solopreneur and I ship apps like a madman. 16 startups in the last 2 years. I realized I was doing the same thing over and over: set up DNS records, connect DB, listen to Stripe webhooks... So I built ShipFast for 2 reasons: 1. Save time and focus on what matters: building a business 2. Avoid headaches like emails ending in spam or waiting 3 days for Google to approve I hope this boilerplate will be as helpful to you as it is for me. Would love your feedback pls Marc

Hey HN! I've been serially building AI projects for over a year, and building node + js SaaS products for over 10 years with my partner. We decided to combine everything we know about AI with our node best-practices into a code boilerplate and see if it can help anyone else! We've had a bunch of positive feedback already from early-users, and at least two SaaS products being developed right now with StartKit.AI as their base. Here's what you get! → Pre-built modules for all common AI tasks: - Chat! Everything to build a ChatGPT clone or your own chatbot. With best-practice implementations of…
