Databento Alternatives (2026)
Databento's strength is schema consistency: normalized data across more than 60 venues with a pay-as-you-go model that suits spiky research usage. The limitation is cost shape: metered pricing works well for targeted pulls but becomes expensive when you need high-volume, continuous feeds at a predictable monthly bill. The right alternative depends on your asset class, budget shape, and latency requirements. Each option below is compared on those dimensions; prices were checked against official pages on 2026-05-26.
On This Page
A licensed market-data provider delivering real-time and historical data for US equities, futures, and options across 60-plus venues through one normalized API. Historical data is pay-as-you-go from roughly $0.50 per gigabyte, with $125 in free credits at signup (expiring after six months). Live and bundled historical access moved to subscription plans: CME Globex MDP 3.0 Standard at $179/month and OPRA options Standard at $199/month, with Plus and Unlimited tiers sold per contract for larger firms.
The Alternatives
4 options worth a look
A developer-first market-data API for US stocks, options, forex, and crypto with a flat monthly subscription and a genuinely usable free tier, which makes it the most common Databento alternative for builders who want a predictable bill.
Pros
- Free tier (end-of-day data, 5 requests/minute) lets you prototype before paying anything
- Flat monthly pricing is easy to forecast: Stocks Starter $29/month, Developer $79/month, Advanced (real-time) $199/month
- Broad asset coverage in one account: stocks, options, forex, and crypto
Cons
- Lower tiers serve 15-minute-delayed data; real-time on stocks requires the $199/month Advanced plan
- Normalization and tick-level depth are less granular than Databento's venue-level schemas
- Per-message historical pulls are less cost-efficient than Databento's $/GB model for very large one-off backfills
Best for: Builders who want a low, predictable monthly fee and a free tier to validate an idea before committing
Market data bundled with a US brokerage and trading API, so the same account that streams quotes can also place orders. The Basic data plan is free on paper and live accounts; the Algo Trader Plus upgrade adds full real-time SIP data.
Pros
- Basic market data is free with any Alpaca trading account, including paper accounts
- Tight integration with the brokerage API removes a second vendor when you also need execution
- Algo Trader Plus ($99/month, included free on Elite accounts) unlocks full real-time consolidated data
Cons
- Coverage is centered on US equities and crypto; no futures or OPRA-grade options depth like Databento
- Data quality and history are tuned for retail-scale algo trading, not institutional microstructure research
- You are tied to Alpaca's brokerage relationship to get the best data terms
Best for: Algo traders who want execution and data from one vendor and can live with US-equities-first coverage
Specialist providers for crypto and crypto-derivatives data. Tardis.dev offers granular tick and order-book history across dozens of exchanges; Kaiko targets institutional crypto market data and indices. Together they cover the asset class Databento does not.
Pros
- Deep historical tick and full order-book data for crypto spot and derivatives venues
- Covers the digital-asset markets Databento's equities, futures, and options focus excludes
- Replay-grade history suited to backtesting market-making and microstructure strategies
Cons
- Narrow to crypto: no equities, listed futures, or OPRA options
- Institutional pricing (especially Kaiko) is quote-based and can exceed a Databento subscription
- Two vendors to manage if you need both traditional and crypto data
Best for: Teams whose strategies live in crypto and need exchange-level order-book history
Buying data straight from the exchange (CME, Nasdaq, NYSE) or a consolidated SIP/UTP feed, often via a redistributor. This is what you graduate to when latency and licensing, not convenience, dominate your cost equation.
Pros
- Lowest achievable latency and the canonical source of truth for each venue
- Full control over licensing, entitlements, and redistribution terms
- No third-party normalization layer between you and the raw feed
Cons
- Exchange fees, redistributor fees, and per-user display/non-display licensing add up fast
- You own normalization, gap recovery, and feed-handler engineering
- Operationally heavy: co-location, capacity planning, and compliance overhead
Best for: Latency-sensitive trading firms where microseconds and direct licensing justify the engineering cost
Decision Table

| Criterion | Databento | Polygon.io | Alpaca | Direct/SIP |
|---|---|---|---|---|
| Pricing model | Pay-as-you-go $/GB + plans | Flat monthly tiers | Free + $99/mo upgrade | Exchange + licensing fees |
| Entry cost | $125 free credits, then usage | Free tier; $29/mo Starter | Free with account | High fixed + per-user fees |
| Asset coverage | US equities, futures, options | Stocks, options, FX, crypto | US equities + crypto | Per-venue, whatever you buy |
| Microstructure depth | Venue-level L2/L3 schemas | Aggregated, lighter depth | Retail-scale | Full raw feed |
| Latency | Low (managed) | Real-time on Advanced tier | Real-time on Plus | Lowest achievable |
| Bundled execution | No | No | Yes (brokerage) | No |
Verdict
If your usage is bursty or research-driven, Databento's pay-as-you-go model and venue-level schemas are hard to beat, and the free credits make it cheap to evaluate. The moment your bill becomes predictable and you want to stop metering, Polygon.io is the cleanest switch: a flat monthly fee, a free tier to prototype on, and enough coverage for most builders. Choose Alpaca when you also need a brokerage and your world is US equities, reach for Tardis.dev or Kaiko when the strategy lives in crypto, and only move to direct exchange or SIP feeds once latency and licensing genuinely dominate your costs, because that path trades a single subscription for real engineering and compliance overhead. Run the numbers on your own volume before deciding; a data-vendor TCO model will usually surface a clearer answer than the headline rate.
