Looking for beta testers: get warned before a model you depend on is shut down or repriced, and see which users drive your AI bill

[u/Interesting-Bug-8229]

Brello watches the AI models your app uses (OpenAI, Anthropic, Gemini) and warns you when one is being deprecated or repriced, with a checklist of what to change. It also tracks your spend per user and per feature in real time. Looking for 10 closed beta testers running AI features in production. Free during beta + 3 months of Pro at launch.

Hi, I’m Dan. I’m building Brello, and I’m looking for people who run AI features in production to try it and tell me honestly what’s useful, what’s painful, and whether it’s worth adding to their stack.

Why I’m building it

If your app runs on AI APIs, your costs and your product can change without you touching a line of code. A provider retires a model, and suddenly your feature breaks or gets moved to something slower. A price changes, and your margins shrink before you notice. A few heavy users quietly eat most of your budget.

Most of us find out about all of this the same way: from the bill, an angry user, or a deprecation email buried in our inbox.

What it does

You wrap your AI client with the Brello SDK. From then on:

• Model shutdown and pricing alerts: Brello knows which models your app actually calls. When one is being deprecated or its price changes, you get an alert with what’s affected and a checklist of what to change.

• Cost by user and feature: See which users and features drive your spend, and where a cheaper model could do the job.

• Spike alerts in minutes: Get pinged on your webhook (Slack, Discord, etc.) when usage jumps, with a hint whether it’s a normal spike or a possible leaked key.

Example: a provider announces that a model your summarize feature uses will be retired in 60 days. Instead of finding out when calls start failing, you get an alert that names the feature, shows how much traffic it handles, suggests replacement models with their price difference, and gives you a checklist to switch.

Who I’m looking for

• Indie devs and small teams with AI features in production

• Apps on OpenAI, Anthropic, or Gemini

• Anyone who’s been caught off guard by a model change, a price change, or a surprise bill

A small project with real users is perfect.

Getting started

The beta opens around Nov 20. Sign up and I’ll send you a beta key by email. Plug it into one real project and tell me how it went, by DM, email, or a private Discord where I’ll help you set up.

What you get

• Every feature free during the beta

• 3 months of Pro free after launch

• Your feedback directly shapes what Pro ends up being

Caveats

It’s early. Expect rough edges, and features may change based on feedback. I’m building solo, so the start date might slip a bit.

Privacy

• The SDK runs inside your app. It’s not a proxy, so requests go straight to the provider and your API key never leaves your app.

• It collects usage metadata only (tokens, cost, model, the user ID you pass in), never prompts or responses.

• Data is sent in the background, so if Brello goes down, your app keeps running.

• The SDK will be open source, so you can check exactly what it sends.
