24 alternatives to FastReact – FastAPI and React Starter Kit for AI SaaS
Hi everyone, I've successfully used Backend + SPA pattern in several AI products so far. Then I decided to put years of experience into this starter pack. Even then, it took me a few months to make it a complete product. It has anything a regular SAAS would require, plus AI-ready features such as token based metering and a fully functional AI copilot demo app. Let me know your feedback.

Open SaaS 2.0▲438I launched Open SaaS about a year and a half ago and surprisingly it’s become one of the most popular free SaaS boilerplate starters on github (https://github.com/wasp/open-saas). After 2 years of work total, I’m pleased to launch what I’m calling “Open SaaS v2.0”. Here’s a breakdown of all the features and updates I’ve made to it over time: * New Big, Shiny Things for v2.0 * - Complete redesign with Shadcn UI for a modern and consistent look (themeability coming soon...). - Script that autogenerates an LLM-friendly version of the documentation…

Hi HN! I've been building ReadyKit, an open-source SaaS boilerplate that handles all the hard parts: multi-tenant workspaces, Stripe billing, OAuth + MFA authentication, and a production-ready stack.

Clone, configure your OAuth and Stripe keys, and you're running in 5 minutes. Features include automatic query scoping for workspace isolation, audit logs, role-based access, and a modern UX kit.

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.

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…

Henry, Matt and James here – we’re building an open source toolkit that makes it easy to integrate an LLM-powered copilot that talks to your API into software products. It works by calling API endpoints which you choose to expose to it. This lets the chatbot complete tasks within your software in response to natural language queries. It’s also open source, so you don’t have to send user data to another 3rd party. We support Llama 2, but we haven’t fine-tuned Llama 2 yet (coming soon) so highest accuracy is seen with GPT-4 or fine-tuned GPT-3.5 (much faster). We started working together 2…
