Overview

About CloudBurn

CloudBurn is a proactive cost intelligence platform built for modern engineering teams. It is specifically designed for developers and DevOps engineers who use Infrastructure-as-Code (IaC) tools like Terraform or AWS CDK to manage their cloud infrastructure. The core mission of CloudBurn is to shift cloud cost management left, integrating it directly into the developer's existing workflow. The traditional model of cloud spending is broken: teams are often blindsided by budget overruns weeks after deployment, when costly resources are already running and the money is spent. CloudBurn changes this reactive paradigm by providing immediate, actionable cost feedback during the code review process. It automatically analyzes infrastructure changes in pull requests, calculates the precise monthly cost impact using real-time AWS pricing data, and posts a clear report as a comment. This empowers developers to have informed discussions about cost versus performance, optimize configurations, and prevent expensive mistakes before code is merged and deployed. By embedding cost visibility seamlessly into GitHub, CloudBurn enables automated FinOps, fosters a cost-aware engineering culture, and delivers immediate return on investment by catching misconfigurations that would otherwise silently inflate the AWS bill.

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.
