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:

* Issue tracker: https://16857470-551d-4f50-8e5b-b7d24a4a874a.http.replay.io

* 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?
