The free Bloomberg: how much of a $24,000 terminal can you rebuild for $0?

We decomposed what a Bloomberg Terminal actually does into layers, rebuilt every layer that free public data allows, and published the result as this site. Here's the build — and the honest list of what can't be rebuilt.

What a terminal actually is

Strip the mystique off a Bloomberg Terminal and it's four things stacked on top of each other. A data layer: prices, macro series, filings, holdings, news — collected from everywhere, cleaned, and delivered in one place. An analytics layer: the models and screens that turn data into judgment — what's trending, what's stressed, what's rich, what's abnormal. A news and narrative layer. And a network layer: chat, execution, the fact that every counterparty is also on it. The seat costs about $24,000 a year — roughly ₹20 lakh in India — whether you use all four layers or one.

Here's the thing that changed over the last decade, quietly: for daily-frequency work, the first three layers are now assembled from public sources. Not approximated — assembled. Exchange disclosure rules, central-bank data portals, regulatory filings and open-source models have moved most of the raw material into the open. What's left behind the paywall is real-time speed, exhaustive breadth, and the network. Those are worth $24,000 to an institution. They are worth very little to someone making daily or weekly decisions with their own capital.

The expensive part of a terminal is no longer the information. It's the speed, the breadth, and the chat. If you don't need those three, the rest can be free.

The build: every layer, sourced

Regime Compass is the proof-of-work for that claim. Every tool on this site runs on data anyone can access, processed by models whose specifications — and whose audited failures — are public. The full stack, source by source:

Two things make this a terminal rather than a pile of dashboards. First, everything updates itself daily — the same discipline a Bloomberg imposes, without the seat. Second, the layers check each other: the regime verdict is only trustworthy because systemic stress, macro, smart money and sentiment are independent streams that can disagree with it. That cross-examination is the actual product; any one signal alone can lie.

What we could not rebuild — and won't pretend to

An honest comparison has a second column. There is no free substitute for:

The line, then, is clean: if your workflow is execution, credit, or intraday, rent the terminal. If your workflow is judgment — what kind of market is this, how fragile is it, what is informed money doing — the free layer now covers it.

Why give it away

Partly because the marginal cost is near zero — the data is public and the models are code. Mostly because publishing forces honesty. A paid terminal never has to show you its accuracy; we publish walk-forward audits of our own models, including the finding that they don't beat buy-and-hold as return-timers — their value is drawdown behavior, not clairvoyance. A free tool that shows its losses is a better instrument than an expensive one that doesn't have to.
