Alternatives, in AI in Markets
Tiingo Alternatives (2026)
Thirty-plus years of clean US stock history available even on the free Starter tier makes Tiingo unusually strong for backtesting. The scope is intentional and limiting: coverage leans US, the emphasis is end-of-day, and intraday, tick data, deep fundamentals, or global markets require something else. Each alternative below covers a specific gap, compared on history depth, coverage, and data granularity; pricing was verified against vendor pages on 2026-05-26 and any figures that differ by source are called out directly.
5 alternatives. Published May 26, 2026. Updated Oct 19, 2026. By AI Fin Hub Research.
A clean, cost-effective market-data API focused on US equities with deep history. Its free Starter tier includes 30+ years of end-of-day stock data, and paid tiers add 15+ years of fundamentals across all tickers (versus about 5 years free). Tiingo has a strong reputation for clean, backtest-ready historical prices at low cost. Its emphasis is end-of-day data and US coverage; it offers less intraday and tick-level granularity than depth-focused providers, and less global breadth than EODHD. Best when you need clean US historical data for research and backtesting without paying for institutional-grade depth.
The alternatives
5 options worth a look
A budget global market-data API. EODHD covers end-of-day data across world markets plus a fundamentals feed, the switch when your backtesting universe extends beyond US markets that Tiingo emphasizes.
Pros
- Strong global exchange coverage at low cost
- Transparent personal tiers (in euros): EOD all-world €19.99/month, all-in-one €99.99/month
- Long historical data and a fundamentals add-on
Cons
- Fundamentals feed is a separate €59.99/month personal add-on
- Intraday and real-time are higher tiers
- US data quality reputation is good but Tiingo is a clean-data benchmark
Best for: Cheap global end-of-day history beyond Tiingo's US focus
A fundamentals-first market-data API. FMP centers on statements, filings, transcripts, and calendars, the switch when your research needs deeper fundamentals than Tiingo's price-focused dataset.
Pros
- Fundamentals-first: statements, filings, transcripts, and calendars are core
- Generous 250-requests/day free tier for evaluation
- Combines prices with deep fundamentals
Cons
- Less emphasis on clean EOD price history than Tiingo
- The free tier's 250 requests a day suits evaluation, not a live universe
Best for: Deep fundamentals, filings, and transcripts over price-focused history
A multi-asset market-data API priced by throughput. It spans stocks, forex, and crypto, the switch when your strategy needs more than US equities from one vendor.
Pros
- Multi-asset coverage (stocks, forex, crypto) from one API
- Clear throughput tiers, each at three credit levels: free Basic, Grow from $29/month, Pro from $99/month, Ultra from $329/month
- Real-time on higher tiers with no daily cap
Cons
- You pay for call rate as you scale
- Less specialized for clean EOD backtesting than Tiingo
- Single-asset depth is good but breadth is the draw
Best for: Multi-asset coverage across stocks, forex, and crypto
A simple, indicator-friendly market-data API. Its built-in technical indicators are the switch when you want price plus computed indicators in one call rather than calculating them on Tiingo's raw prices.
Pros
- Built-in technical indicators returned directly from the API
- Simple, beginner-friendly endpoints
- Transparent rate-tiered premium pricing
Cons
- Free key hard-capped at 25 requests/day, slow for bulk historical pulls
- Premium scales by per-minute rate ($49.99-$249.99/month)
- Less clean-history reputation than Tiingo for backtesting
Best for: Built-in technical indicators without computing them yourself
A depth-focused US market-data API. Polygon (rebranded to Massive in late 2025) offers granular intraday and tick-level data on US equities and options, the switch when EOD bars are not enough for your strategy.
Pros
- Granular intraday and tick-level US equities and options data
- Clear Stocks tiers: free Basic, $29 Starter, $79 Developer (delayed), $199 Advanced (real-time SIP)
- Deep history (20+ years on Advanced)
Cons
- Real-time SIP starts at the $199 Advanced tier, not the cheaper plans
- US-focused (separate ladders for options, indices, FX/crypto)
- More than you need for pure EOD backtesting
Best for: Granular intraday and tick data when EOD bars are insufficient

Verdict
Tiingo is already a strong, cheap choice for clean US end-of-day history and backtesting, with 30+ years available even on its free tier, so keep it for that job. Switch for the gap. Choose EODHD when your universe spans global markets and you want cheap EOD breadth. Pick Financial Modeling Prep when fundamentals, filings, and transcripts depth matters. Reach for Twelve Data when you need stocks, forex, and crypto from one vendor, Alpha Vantage when built-in indicators save you compute, and Polygon (now Massive) when you need granular intraday or tick-level US data that EOD bars cannot provide. Coverage breadth and data granularity decide most of these.

Questions people ask next
What is the best Tiingo alternative for global market coverage?
EODHD. Tiingo is US-focused, so when your backtesting or research universe spans world markets, EODHD's end-of-day coverage across global exchanges is the natural switch, with transparent, cheap personal pricing (EOD all-world at €19.99/month). It also offers long historical data and a fundamentals add-on. Twelve Data is the alternative if you need multiple asset classes (forex and crypto alongside stocks) globally with throughput-tiered pricing. For the cheapest path to wide global EOD history, EODHD leads; Tiingo remains the cleaner choice if you only need US data and value its data-quality reputation for backtesting.
Which Tiingo alternative offers intraday or tick data?
Polygon (now Massive) for the deepest granularity, with Twelve Data and EODHD offering intraday on higher tiers. Tiingo emphasizes end-of-day data, so when your strategy needs intraday bars or tick-level detail, you switch. Polygon provides granular intraday and tick-level US equities and options data, with full real-time SIP on its $199 Advanced tier (cheaper tiers are 15-minute-delayed). Twelve Data includes intraday on its paid throughput tiers across multiple asset classes. For microstructure-aware or intraday strategies on US markets, Polygon's tick-level depth is the strongest fit; for EOD backtesting, Tiingo's clean history is enough.
Which Tiingo alternative has the deepest fundamentals?
Financial Modeling Prep (FMP). Tiingo offers US fundamentals (about 5 years free, 15+ years on premium), but FMP is fundamentals-first by design: financial statements, SEC filings, earnings-call transcripts, and corporate calendars are the core product, with a 250-requests-per-day free tier for evaluation. If your strategy reasons over company fundamentals and filings in depth rather than primarily on price history, FMP's coverage is the stronger fit. FMP's paid plans run $29, $69 and $139 a month.
