A CCXT alternative? Only for the data layer.
CCXT is an open-source library that connects your code to the APIs of 100+ exchanges, for market data and trading, in JavaScript, Python, PHP, C# and Go.
DEBYKO is a hosted service that collects perpetual-futures data from 16 venues and serves every value with the venue's time and a status that says whether it is still current [7].
With CCXT, your application is the collector. With DEBYKO, the collector is the service. That is the whole comparison; the rest is detail.

Who runs what
| Layer | CCXT gives you | You still own | DEBYKO runs |
|---|---|---|---|
| Exchange connectivity | Unified REST client per exchange; WebSocket watch* methods via CCXT Pro, included in the package [1][3] | The process that holds the connections, credentials, IP limits | Collectors on 16 perpetual venues [7] |
| Normalisation | Unified symbols and market structures; exchange-specific params pass-through [2] | Mapping edge cases your code depends on | One model across venues; venue quirks documented per venue card [8] |
| Continuous collection | — | Scheduling, reconnects, subscription state, retries, dedup | Collection, outage records, gap records [8] |
| Persistence and history | fetchOHLCV, fetchTrades, fetchFundingRateHistory, fetchOpenInterestHistory: what the exchange's API keeps [2] | Database, retention, backfills | Retained history since September 2026, as-of queries, daily Merkle root on Base [7][9] |
| Freshness decision | Timestamps on unified structures [2] | Whether a value is still usable | Status, reason and validity horizon on every value [8] |
| Querying across venues | — | Your own loop over instruments and exchanges | DQL conditions across venues; MCP for AI clients; Agent alerts [8] |
| Trading and private APIs | createOrder, cancelOrder, fetchBalance, fetchOpenOrders on supported exchanges [2] | Keys, risk controls | — (DEBYKO does not place orders) |
1. An abstraction is not a collector
CCXT standardises how you call an exchange. It does not run anything for you: no process, no storage, no history of its own, no cross-exchange database [1][2]. A team that wants those builds them on top of CCXT, and many do; owning the pipeline is a legitimate choice.
As published on 2026-10-09: 100+ exchanges, currently 103 on the manual's exchange list [1][2]; JavaScript, Python, PHP, C# and Go [1]; MIT licence [1]; CCXT Pro is a free part of CCXT and its WebSocket methods ship inside the open-source package [3]; unified methods for funding rates, funding history, open interest and open-interest history where the exchange exposes them [2].
2. Rate limits
CCXT's enableRateLimit throttles requests per exchange instance. It is on by default. Each instance has its own limiter, and the manual says not to use multiple instances of the same exchange with the same key from the same IP [2]. It helps you stay under a limit. It does not create capacity: ten workers with ten instances still share the exchange's quota.
DEBYKO consumers query DEBYKO instead of the venues for the values it already collects. That is not unlimited either: plans have per-second and daily request limits [7]. Snapshots and candles are also sold per request over x402 in USDC on Base, from $0.005 a call, without an account.
3. History: what the exchange keeps versus what was collected
fetchOHLCV and the history methods return what the exchange's API returns, paginated by since and limit, with per-exchange windows and gaps you handle yourself [2]. Many exchanges keep candles for years and trades for days; it differs by venue.
DEBYKO returns what it collected, from September 2026, with at for the state at an instant, interval for a sampled range and raw for the rows as received [8]. Neither is deeper by definition. For years of candles, the exchange API through CCXT; for the state of a value at a moment, with its status, DEBYKO.
4. Freshness
CCXT gives you timestamps on unified structures and errors on failed calls [2]. Whether a value you received two minutes ago is still usable is your decision, in your code, per venue.
DEBYKO makes that decision in the API. The horizon is one of measured, documented, assumed, venue_declared or connection.

}
}Past the horizon the number leaves the value field and stale with a reason takes its place; missing, not_published and off are distinct states. A missing open-interest value is not zero open interest [8].
5. Trading is a separate decision
DEBYKO does not place orders. If you need createOrder, you need CCXT or another execution integration whatever you use for data. The two fit together.
┌── DEBYKO ── screening (DQL), values with status, as-of history
Strategy engine ───┤
└── CCXT ──── authenticated execution on the exchangeDEBYKO screens and reports state; your code verifies what it needs at execution time; CCXT sends the order; your risk controls decide whether it may be sent. Neither product provides the risk layer.
A $0 licence is not $0 infrastructure: compute, storage, backups, monitoring and incident response for a 16-venue collector are yours with CCXT and part of the subscription with DEBYKO. A subscription is not $0 engineering either; integration, validation and execution stay with you.
Where each one is ahead.
Where CCXT is ahead
Where DEBYKO differs
- Stored as published: venue time and received time on every value.
- A status instead of a stale number, with the reason.
- Collection, outages and gaps recorded for you.
- DQL across venues; MCP server; Agent alerts to Telegram.
- Sealed daily on Base: stored rows verifiable against a public root. This shows the rows match the commitment, not that the exchange was right.
- Free plan without a card; pay per request over x402.
CCXT for the calls you want to own, including orders. DEBYKO for perpetual values with a status, without running the collectors. The diagram above is the shape when a strategy needs both.
Decide in six questions
- Need authenticated order placement? CCXT or another execution library, regardless of data source.
- Need native parameters and full control of connections? CCXT.
- Want to collect and persist every venue yourself? CCXT is a fine base.
- Want cross-venue perpetual values with a usability status, without running collectors? DEBYKO.
- Need history before September 2026? DEBYKO alone cannot supply it.
- Need both screening and execution? Use both.
Questions.
Is DEBYKO a CCXT replacement?
For the market-data layer on perpetuals, it can be. For trading, no.
Does CCXT have WebSockets?
Yes: CCXT Pro's watch methods, included in the open-source package [3].
Does CCXT have historical data?
It fetches what the exchange's API keeps; it does not host history of its own [2].
Does DEBYKO place orders?
No.
Can I use both?
Yes. DEBYKO for screening and the state of values; CCXT for authenticated execution.
