Hey HN, we're building a library of open source SaaS apps for small businesses and personal use. You can browse the apps at https://builder.replay.io, these are free to copy or download and use however you want. Examples:

* https://builder.replay.io/gallery/Sales%20CRM — Sales CRM with pipeline view and deal tracking * https://builder.replay.io/gallery/Issue%20Tracker — Issue tracker with projects and triage view * https://builder.replay.io/gallery/Team%20Wiki - Internal docs with nested pages and customizable tables * https://builder.replay.io/gallery/Invoicerator — Time tracking + invoice generation for freelancers * https://builder.replay.io/gallery/Accounterize - Accounting system for tracking financial transactions * https://builder.replay.io/gallery/Inventory%20Tracker - Inventory management for production facilities

We love building bespoke software with AI, but many businesses have needs for similar tools and we want to strike a middle ground between having to build something from scratch or pay for expensive and immutable off the shelf software.

These apps have comprehensive, passing test suites and are a good place to start for a vibe coding project, but we're also building out the apps (and their test suites) into complete tools ready for immediate use. See more here: https://blog.replay.io/communal-saas-apps

If you're interested in using these you can sign up as an early adopter on any of the app landing pages, and we'll support you to make sure things are working great.

Hi HN, I'm the CEO at https://replay.io. We've been working on time travel debugging for web development for a while (https://news.ycombinator.com/item?id=28539247) and more recently an AI app builder that uses that debugger to get past problems instead of spinning in circles (https://news.ycombinator.com/item?id=43258585).

We've gotten to where we can pretty easily build apps to replace business-critical SaaS tools, some of which we're now using internally:

* We built our own issue tracker to keep track of all our development projects, tickets, bug fixes, and so on, completely replacing Linear.

* We built a knowledge base for managing internal documentation and the status of ongoing initiatives, completely replacing Notion.

* We built a telemetry system that ingests OTLP events via a webhook and supports custom graphs and visualizations, mostly replacing Honeycomb.

We want to have as much control as we can of the apps we need to run Replay. We can tailor these apps to our needs, completely own them and their data, and avoid hostile SaaS vendor behavior like per seat pricing, paywalled features, locking us into their platform, and locking us out from accessing our own data.

Today we're launching Builder (https://builder.replay.io/), the tool we used to make these apps, along with the apps themselves and others we've built. You can copy these apps for free, download the source and self host them if you want, or let us take care of hosting, fixing bugs, and modifying them for your needs.

If you want to just check these out, here are a couple (shared, no login required) copies of these apps:

* Knowledge base: https://d7e0dff4-f45c-4677-9560-6ea739c00a94.http.replay.io

We're excited for the power of AI app builders to accelerate the pace of software development, unlock the creativity of non-developers everywhere, and especially to help erode the control that so many large companies have over us. We're continuously building new apps ourselves to help in this endeavor, so let us know what you think! What are the apps and vendors that frustrate you the most?

Hi HN, I'm the CEO at https://replay.io. We've been working for several months on helping AIs be proficient at using our time travel debugger to fix broken web apps (previous post: https://news.ycombinator.com/item?id=43258585)

Today we're launching https://nut.new to roll these capabilities into a complete app builder for one shotting working web apps.

When you ask Nut for an app, it discusses the requirements with you and develops a plan: how the pages will be laid out, the different features, database specification, APIs the app will use, tests that are needed, and so on.

Nut builds a non-functional mockup first, then implements working versions of the app’s components, then writes tests for those components and fixes the problems they surface using Replay's time travel debugger. All this is done in parallel, with workers merging changes into the app only when all tests pass, as professional engineers would do.

We want building basic web apps with AI to work reliably and with barely any effort, like waving a magic wand. We're not quite there yet, but we've been enjoying building apps with Nut quite a bit and want to share it with you.
