24 alternatives to Srcbook – Self-hosted alternative to AI app builders
Today we’re releasing a full AI app builder in Srcbook. We released our TypeScript notebook a few months ago (https://news.ycombinator.com/item?id=41291700) and the response was encouraging, but we kept hearing that people wanted to build interactive apps. Today we are releasing just that. You can think of it as an open-source and local version of vercel’s v0. We actually think of it as something in between an IDE and that, because we believe the code matters and don’t shy away from that: you can view and edit the code in a full editor, but prompt your way forward if that's…
Srcbook is a self-hosted AI app builder that lets developers create interactive applications using TypeScript. It combines an IDE with AI-assisted development, allowing users to write and edit code directly or use… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Prices are shown for the 1 we have checked on their own sites, 1 of them free or with a free tier. Srcbook – Self-hosted alternative to AI app builders launched in 2024; newer entries below may have overtaken it.

Srcbook (”source-book”) is an open-source TypeScript notebook that runs locally, powered by Node.js. It shines for rapid prototyping, code exploration, and collaborating on ideas. It’s inspired by Python’s Jupyter and Elixir’s Livebook. Key features: - Full npm ecosystem access - AI-assisted coding (OpenAI, Anthropic, or local models), it can iterate on the cells for you with a code diff UX that you accept/reject for a given code cell, generate entire Srcbooks, fix compilation issues, etc… - Exports to valid markdown for easy sharing and version control Try it now: `npx srcbook start`…

SimplAIfree tier, from $5/mo▲589Hey HN, I've been building SimplAI for the past several months — it's a platform for building, testing, and deploying LLM-powered agents and multi-step workflows. The problem I kept running into: spinning up an AI agent pipeline means stitching together prompt management, tool calling, memory, evals, and deployment — often from scratch every time. SimplAI tries to be the layer that handles all of that so you can focus on what your agent actually does. What it does: - Visual + code-first workflow builder for chaining LLM calls, tools, and APIs - Built-in prompt versioning and A/B testing…

Hi HN community! We want to share AI-town, a deployable starter kit for building and customizing your own version of AI simulation - a virtual town where AI characters live, chat and socialize. Inspired by great work from the Stanford Generative Agent paper (https://arxiv.org/abs/2304.03442). A few features: - Includes a convex.dev backed server-side game engine that handles global state - Multiplayer ready. Deployment ready - 100% Typescript - Easily customizable. You can fork it, change character memories, add new sprites/tiles and you have a custom AI simulation…

Hey everyone, Really excited to share what I've been working on. Rapidpages is a prompt-first online IDE, think midjourney for front-end developers. I've been working on this for a while and it's great to see some interest from companies like Vercel in this space. All you need for self-hosting is an OpenAI key and a GitHub oauth app. Simply clone the repo and play with it. It's also available on the cloud at www.rapidpages.io Please give it a try and let me know if you have any feedback, and if you like what I'm doing with Rapidpages, please give it a star on GitHub. Thanks!

Budibase 2.0▲381Hi there, Mike here from Budibase. We’ve recently launched AI Agents into Beta, alongside our existing open-source app-building and automation tools. We built Budibase Agents for teams that want to leverage AI within real-world workflows, using their own LLMs, data, and APIs. Because of this, our Agents can be powered by any LLM with an OpenAI-compatible API, including open-source and locally-hosted models. This means you can build Agents that connect to your existing toolstack, within your own environment. Some more details: - Agents' behavior is configured using natural language…

Hey, Jared Palmer (creator of this playground) here. Really excited to ship this. I’ve been building this over the past few weeks to compare LLMs from different providers like OpenAI, Anthropic, Cohere, etc. At Vercel, I manage our Frameworks division (including Next.js, Svelte, and Turbo) and wanted to also dogfood some of the latest features in a slightly larger application. This playground takes a lot of inspiration from https://nat.dev and is built on Tailwind, ui.shadcn.com, and some upcoming Vercel products we’re announcing soon. We’re going to continue adding models to…

I've been exploring the (not so=) amazing potential of AI in coding and have compiled a list of tools. From AI-powered IDEs to code generators, this resource is my contribution to the community. I'm still on the fence about including txt2sql projects, as their functionality seems too basic to me. And I'm personally maintaining this, so your feedback is wellcome.

We just open sourced a first class our AI web app builder. Instead of using another hosted AI coding platform, you can fork this project and build your own AI app builder, fully customized and running under your own brand. It includes: Next.js + TypeScript AI chat with streaming Artifact generation File explorer Code editor Live preview Databases Sandboxes to be used by AI agents Versions Responsive production-ready UI And a lot more... The only required dependency is the Totalum API, which exposes the AI generation engine through a simple REST API. You can replace or extend the backend…

Hey HN! A few months ago we shared our AI dataset generator as an open source repo, and the response was incredible (https://news.ycombinator.com/item?id=44388093). We got requests from folks who wanted to use it without the hosting overhead, so we created both options: a hosted version (https://www.metabase.com/ai-data-generator for instant use and the source code fully open (https://github.com/metabase/dataset-generator) for anyone who wants to self-host or contribute. Looking forward to seeing how you use it and what you build on top of…
