Live demo, no signup: https://costbase.co/demoHi there, over the past 1-2 years I ve built and experimented with many AI apps. Some are in production, some died in the experimental stage.The ones in production currently costs me ~$500 a month to run – using a variety of models from OpenAI s Whisper to Anthropic LLM.Because it s important for me to track the Cost of Goods Sold of each individual app, the strategy I ve used so far is to use a different credit card for my few apps. However, that obviously does not work the more apps I build.This is why I built Costbase – a simple app that just requires that I paste in an admin key with no code change (and no proxy sitting between my app and the AI provider) – and show me the cost of my AI bill broken down by apps and not API keys.I intentionally kept this product as simple as possible – something I would actually like to use. I know there are observability tools like Helicone that are much more capable. But to be honest I didn t even try out the competitor and just built something I d like to use myself.I d like to hear from the community to see if anyone feel a product like Costbase is genuinely useful.Let me know your thoughts in the comments.(I m in Taipei so going to sleep in about two hours. Will be back tomorrow morning to answer any additional comments)
