Not ideal for
Teams using non-OpenAI AI providers (Anthropic, Google)Enterprises requiring advanced analytics or RBACUsers who need mobile apps or CLI tools
Puddl is a solid free choice for basic OpenAI cost tracking, but limited in scope. If you only use OpenAI and want a simple dashboard, it's great. For multi-provider or complex team needs, look elsewhere.

About Puddl
FreemiumBeginner-friendlyNo APIWeb
Puddl is a lightweight, purpose-built tool for developers and teams who use OpenAI APIs and want granular insight into their spending. It hooks into your OpenAI account via API key integration to automatically pull usage data, breaking costs down by model, endpoint, user, and time period. The service offers a clean dashboard that shows both current month's spend and historical trends, with soft spending limits and email alerts to prevent budget surprises. Designed for solo developers, small startups, and larger engineering teams, Puddl requires no code changes — just connect your OpenAI account and start monitoring. The free tier covers up to 100,000 API calls per month, which is sufficient for many hobbyist and early-stage projects. The platform is entirely web-based, with no desktop or mobile apps, and it does not offer a public API for programmatic access. What sets Puddl apart is its simplicity and zero cost for most users. While many monitoring solutions are expensive or overly complex, Puddl provides essential cost tracking without a monthly fee for the basic tier. The tradeoff is that it only supports OpenAI — no other AI providers — and lacks advanced analytics or multi-team features found in enterprise tools.
Behind the Verdict
Puddl solves a real pain point for developers: surprise OpenAI bills. Its free tier (100k calls/month) is unusually generous and covers hobbyists and early-stage projects. The interface is clean and straightforward, and the cost breakdown by model and endpoint helps you optimize usage. However, the tool is single-provider only (OpenAI), has no mobile app, and lacks advanced features like role-based access control or team quotas. The Pro tier at $9/month is affordable and adds 1M calls/month and unlimited history, but still limited to OpenAI. For teams using multiple AI providers, you'd need a more comprehensive solution. Puddl is best as a lightweight, no-commitment cost tracker for solo developers or small teams deeply embedded in OpenAI.

Where the pricing makes sense
The company stage and team size where Puddl's pricing actually pencils out — and where peers do it cheaper.
Puddl's free tier is hard to beat for cost-conscious solo devs and micro-startups. At $9/month for Pro, it's cheaper than most alternatives (e.g., Helicone's free tier with limited history). But if you need multi-provider support or advanced analytics, expect to pay more elsewhere.
Setup time & first value
How long it actually takes to get something useful out of Puddl — broken out by persona, not the marketing-page minute.
A solo developer can set up Puddl in under 5 minutes: sign up, paste OpenAI API key, and dashboard loads. For team invites, add 2 minutes per member.
