Overview
About CloudBurn
Alright, let's talk about the cloud bill monster that's been giving your team nightmares. You know the drill: you merge a PR, your Terraform or AWS CDK stack does its thing, and you're feeling like a DevOps wizard. Then the end of the month hits, and BAM! Your AWS bill looks like it got hit by a freight train. Where did that extra $5K come from? Was it the new RDS instance? The accidentally public S3 bucket? It's a mystery that ruins your day and your budget. CloudBurn is here to be your financial bodyguard. It's the tool that slaps a price tag on your infrastructure code before it ever touches production. By integrating directly into your GitHub pull requests, it gives you and your team a real-time, line-by-line cost estimate of every change. Think of it as a crystal ball for your cloud spend, letting you catch those "oopsie" $10,000 configurations while they're still just code in a review. No more spreadsheet sorcery or post-deployment panic attacks. CloudBurn makes cost awareness a natural part of the dev workflow, so you can build with confidence and keep your finance team from having a meltdown.
About OpenMark AI
OpenMark AI is a web application for task-level LLM benchmarking. You describe what you want to test in plain language, run the same prompts against many models in one session, and compare cost per request, latency, scored quality, and stability across repeat runs, so you see variance, not a single lucky output.
The product is built for developers and product teams who need to choose or validate a model before shipping an AI feature. Hosted benchmarking uses credits, so you do not need to configure separate OpenAI, Anthropic, or Google API keys for every comparison.
You get side-by-side results with real API calls to models, not cached marketing numbers. Use it when you care about cost efficiency (quality relative to what you pay), not just the cheapest token price on a datasheet.
OpenMark AI supports a large catalog of models and focuses on pre-deployment decisions: which model fits this workflow, at what cost, and whether outputs are consistent when you run the same task again. Free and paid plans are available; details are shown in the in-app billing section.
