The lean AI stack that replaced 4 analyst subscriptions

By Eric Palmer · Founder, Brainfile · Published April 21, 2026

I run an algo trading service, a Claude Code OS product, a prompt-training platform, a skills marketplace, and two daily newsletters. One person.

Before I started using AI coding tools seriously, I paid for four analyst subscriptions:

ToolWhat it was for
Bloomberg Terminal (shared)Data feeds and news
Koyfin ProDashboards and charts (Koyfin pricing →)
TrendSpider PremiumTechnical charting (TrendSpider pricing →)
Benzinga EssentialNewsroom and market news

I don't pay any of that now. Here's what replaced it.

The current stack

1. Claude Code — on a Claude Pro plan or above

This is the most important line item. Claude Code is the reason one person can run six companies. Every repetitive decision, every dashboard build, every piece of customer content starts as a prompt to Claude and ends as shipped code.

What it replaces: hiring a junior developer and a copywriter and an analyst. One Claude subscription does the work of three people, because the work is now "tell Claude what you need, verify, ship."

Annoying detail: Anthropic's newer Opus models can use more tokens than older versions for the same work. Same rate card, so the real bill per session goes up. Watch your usage if you're running large CLAUDE.md files. (See Brainfile for how I manage this.)

2. FRED (Federal Reserve Economic Data) — $0

Free, official, comprehensive. I use it for: recession probability, GDPNow, CPI (including the Atlanta flexible series), DXY, AAII sentiment, consumer sentiment, balance sheet + M2 + reverse repo, Fed funds forecasts.

What it replaces: every "macro dashboard" feature in Bloomberg / Koyfin / TrendSpider that's just visualizing FRED data with a fancier UI. The data is free. The UI was the subscription fee.

3. SpotGamma-style options flow — a paid GEX data service

I pull SPX gamma exposure, put/call ratios, VIX term structure, and dealer positioning. The specific service isn't the point — any GEX data service covers what the "options flow" premium tier of most brokerages sells.

4. GDELT — $0

Free global news sentiment feed from the University of Illinois. I use it to track macro narrative flow, geopolitical risk, and sector sentiment. Raw data, not curated — but Claude Code can parse it.

5. TradingView (lite) — a lower paid plan

Charts, basic screeners, watchlist alerts. Doesn't have the analyst tools the expensive tiers advertise, but I don't need them — my own algo does the analysis.

6. Massive, formerly Polygon.io (market data) — a starter plan

Raw OHLC price data for the algo. This is the one that actually matters — everything downstream depends on clean price data. Polygon.io is now called Massive (the rename →); current plans: Massive pricing →.

Two of the six are free. Together they replace the four legacy subscriptions, plus they do things none of them could (generate content, ship code, run backtests on demand).

What the expensive tools did that this stack doesn't

Being honest about the tradeoff:

The tradeoff is: I pay with my time and Claude's tokens to get custom versions of what they had. For six companies running lean, that tradeoff is correct.

How Claude Code ties it all together

The stack works because Claude Code is the glue. When I need a new analysis, I don't switch tools — I tell Claude "pull FRED DXY + GDELT tariff sentiment + our options flow data, and tell me if the regime has changed in the last 72 hours." It writes the code, runs it, gives me the answer.

That's the real multiplier. It's not that each tool is cheaper individually — it's that I don't have to context-switch between five dashboards. The analysis comes to me, synthesized.

What to do with this

If you want to build your own version:

Start with Claude Code on a Claude Pro plan, FRED (free) and a lower TradingView plan (TradingView pricing →). That replaces the research tier of most brokerages. Add Massive (formerly Polygon.io) or a GEX service when the free data isn't enough.
