Overview

About CloudBurn

CloudBurn is a revolutionary tool designed to be the financial safety net for modern engineering teams, transforming how they manage cloud infrastructure costs. Aimed primarily at developers and platform engineers who utilize Terraform or AWS CDK, CloudBurn addresses the common frustration of unexpected AWS bills that arrive after deployment. The traditional process involves coding, deploying infrastructure, and later discovering the financial repercussions when the bill arrives, often weeks later and after architectural decisions have been finalized. This scenario can lead to costly and risky rework. CloudBurn changes this narrative by shifting cost visibility to the moment of infrastructure creation. By integrating seamlessly into your GitHub workflow, it automatically analyzes pull requests for infrastructure changes, providing instant line-item cost reports based on real-time AWS pricing data. This proactive approach empowers teams to make informed architectural decisions, ensuring that financial governance is an integral part of the development process from the very first commit.

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.
