Overview

About CloudBurn

CloudBurn is the proactive FinOps shield engineered for modern development teams deploying on AWS. It's built specifically for developers and platform engineers using Terraform or AWS CDK who are tired of the reactive, post-mortem shock of a spiraling cloud bill. The core problem it tackles is the critical absence of a financial feedback loop during the development cycle. Teams currently make infrastructure changes in isolation, deploy them, and only discover the cost impact weeks later when the bill arrives—long after changes are costly and risky to undo. CloudBurn flips this broken model on its head by injecting real-time, actionable AWS cost intelligence directly into the code review process. When a pull request with infrastructure changes is opened, CloudBurn automatically analyzes the diff, calculates the precise monthly cost impact using live AWS pricing data, and posts a clear, detailed report as a PR comment. This transforms cost from a post-deployment accounting surprise into a first-class, pre-deployment engineering metric. It empowers teams to debate, optimize, and prevent expensive mistakes while the code is still in review and changes are trivial to make. By integrating seamlessly into your existing GitHub CI/CD workflow, CloudBurn enables a culture of cost-aware development, delivers immediate ROI by catching costly misconfigurations early, and ensures your team ships infrastructure with both performance and budget in mind.

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.
