Inverse Cramer — a site that runs itself
A site that automatically inverts Jim Cramer’s market calls in real time — when he says buy, the market has a habit of doing the opposite. Built end-to-end, runs unattended.
- Polls public tweets on the X API free tier — no paid API anywhere in the pipeline.
- An LLM generates the inverse interpretation; Cloudflare’s serverless edge stores and serves it, Pages hosts the frontend.
- Total infrastructure cost: the domain plus pennies of AI usage. Real user traffic since launch.

Servers to patch — everything is serverless edge
Why build a joke this seriously
The premise is satire; the engineering is not. The interesting problem was building a pipeline that ingests, interprets, and publishes in real time with zero standing infrastructure — the same cost-discipline pattern I apply to production platforms, pushed to its extreme.
How it runs
Public tweets come in through the X API free tier. An LLM produces the contrarian read. Cloudflare’s serverless edge stores the results and serves them globally, with the frontend on Cloudflare Pages. There is nothing to scale, patch, or wake up for — the whole thing costs a domain registration and a trickle of AI tokens.
So I built Inverse Cramer — a site that automatically flips the meaning of Jim Cramer’s tweets in real time. Jim Cramer is often viewed as a contrarian signal on Wall Street — when he says buy, the market often does the opposite.
