Pulling crypto data into an application looks simple until you try it with more than one exchange. Every venue has its own API structure, its own authentication scheme, its own rate limits, and its own idea of what a “transaction” even is. Binance returns one shape. Kraken returns another. Coinbase deprecates an endpoint on a Tuesday, and by Wednesday your reconciliation job is quietly producing numbers nobody can explain.
Two tools come up in almost every conversation about fixing this: CCXT and Vezgo. They get compared constantly, usually as though they are competitors fighting over the same territory. They aren’t, quite. They solve different halves of the same problem, and knowing which half you’re standing in is most of the decision.
This guide walks through what each one is, what it genuinely does well, where each falls down, and how to choose between them, or run both.
What is CCXT?

CCXT stands for CryptoCurrency eXchange Trading library. It is an open-source, MIT-licensed library that gives developers one unified interface for connecting to cryptocurrency exchanges: fetching market data, checking balances, placing and cancelling orders, and reading account history.
It has been maintained in the open on GitHub for the better part of a decade, and it has grown into something close to infrastructure for the algorithmic trading world. If you have ever used Freqtrade, OctoBot, or almost any open-source trading bot, you have used CCXT without necessarily knowing it.
The library is available in JavaScript and TypeScript, Python, PHP, C#, Go, and Java, and it runs in Node, Python 3, PHP 8.1+, .NET, Go 1.20+, Java 21+, and directly in the browser. That range is unusual for a project of this kind, and it is a large part of why CCXT ended up everywhere.
How Many Exchanges Does CCXT Support?
More than 100. At the time of writing, the library lists 105 supported exchange markets and trading APIs, including centralized venues like Binance, Bybit, OKX, KuCoin, Gate, Bitget, HTX, MEXC, Crypto.com, and BitMEX, alongside decentralized and perpetual venues such as Hyperliquid, Apex, and Backpack. A subset carries a “certified” badge, meaning the integration is actively maintained to a higher standard.
The exact number moves. Exchanges get added, some get delisted when they shut down or restrict API access, and the supported exchanges list in the repository wiki is the only version worth trusting on any given day.
CCXT vs CCXT Pro
This trips people up regularly, because a lot of older tutorials are out of date.
CCXT Pro was originally a separate, paid add-on that handled WebSocket streaming while the free library handled REST. The streaming functionality now ships inside the main package. In practice, this means fetchTicker() (a REST request) and watchTicker() (a live stream) sit side by side in the same install, and the “Pro” label mostly survives as documentation and as a per-exchange badge telling you which venues have streaming implemented.
If you are choosing a library today, you don’t need to hunt for a separate Pro package.
What CCXT Does Well
For quantitative developers and algorithmic traders, CCXT is usually the default, and for good reason.
- It is built for execution. Placing orders, cancelling them, reading live order books, and managing positions are first-class operations, not afterthoughts. If your application needs to do something on an exchange rather than just read from it, this is the tool.
- It is free and genuinely open. MIT licence, no subscription, no vendor negotiation. For independent developers and small quant teams, that alone settles it.
- The language coverage is unmatched. Whatever your stack, there is a good chance CCXT already speaks it.
- The community is large and fast. New exchanges, new endpoints, and new market types tend to land in the library quickly, and recent work has extended the same unified interface beyond spot and derivatives into newer venue types.
Where CCXT Gets Expensive
The catch isn’t the code. It’s everything around the code.
- You host it, so you maintain it: CCXT is a library, not a service. When an exchange changes an endpoint, rotates an authentication requirement, or alters a response payload, your application breaks until someone updates the package, tests it, and redeploys. Across a dozen integrations, that is not a one-off task. It is a standing rota.
- Rate limits become your engineering problem: Because every request originates from your infrastructure, you are the one managing dozens of different rate-limit regimes, backoff logic, and request queues. Get it wrong at scale and you are dealing with IP bans, not error codes.
- Normalization stops where trading stops: CCXT unifies the calls beautifully. The data behind them is less consistent than it first appears, particularly for transaction histories, internal transfers, staking rewards, earn products, and sub-account movements. Those are exactly the fields a portfolio or tax product depends on, and you will spend real time reconciling them.
- Exchanges are only part of a portfolio: CCXT covers exchanges. It does not read a user’s self-custody wallet, follow an xPub across derived addresses, or price a DeFi position. If your product promises a complete net-worth view, the library gets you part of the way and no further.
- Multi-tenant key custody is a genuine liability: A solo trader storing their own API keys locally has a small problem. A platform storing API keys for 40,000 users has a compliance and security programme, complete with encryption at rest, key rotation, incident response, and an auditor asking questions.
What is Vezgo?

Vezgo is a managed, read-only crypto data API built by Wealthica, the investment portfolio tracking company. It launched in September 2021 and is SOC 2 Type 2 certified.
CCXT is code you run. Vezgo is a service you call. Instead of maintaining connections to each exchange yourself, you integrate once with Vezgo’s API, and Vezgo maintains everything upstream: the connections, the credential handling, the normalization, and the breakages.
It is built specifically for applications that need to read a user’s crypto position accurately and continuously: portfolio trackers, tax software, accounting tools, wealth management platforms, and financial dashboards.
What Vezgo Does Well
- The maintenance burden moves off your team. When an exchange changes its API, Vezgo updates the integration. Your endpoint doesn’t change, your payload doesn’t change, and you don’t redeploy. Over a year, this is the difference that shows up in your roadmap.
- Normalization is the actual product. A deposit on Coinbase arrives in the same shape as a deposit on Kraken. Balances, transactions, and asset metadata are standardized across every supported integration, which removes the messiest and least rewarding work in the entire build.
- Coverage goes past exchanges. Vezgo connects around 40 centralized exchanges, 20 blockchains, 250 wallets, and NFT assets on EVM chains, with the current list published on the integrations status page. Wallet support includes xPub and yPub tracking, so a Bitcoin wallet’s derived addresses resolve into one coherent balance rather than a pile of unrelated addresses.
- Security is handled as a product requirement, not a to-do. Credentials sit behind AES-256 encryption in SOC 2 Type 2 audited infrastructure, and access is read-only by design. Private keys are never in play. For a regulated wealth manager or a fintech going through vendor review, that posture is frequently non-negotiable.
- It is built for many users, not one. Accounts sync daily, data is stored so you aren’t re-fetching everything on every page load, and a client portal handles user and team management. A drop-in Connect widget covers the account-linking flow, which is otherwise a surprisingly fiddly piece of UI to build well.
Where Vezgo isn’t the Answer
- It doesn’t trade: Vezgo is read-only, deliberately. If your product places orders, routes execution, or runs a market-making strategy, this is the wrong tool and no amount of clever engineering changes that.
- It’s a paid service: You’re buying managed infrastructure, an audited security posture, and someone else’s maintenance rota. That is a real cost, and it should be weighed against a salaried engineer’s time rather than against zero.
CCXT and Vezgo- A Critical Comparison

CCXT is a fantastic tool that packs several functions, making it an excellent crypto exchange API, especially for trading purpose. For researchers, it’s a dream come true. However, it does have a number of demerits compared to Vezgo.
For starters, Vezgo is quite easy-to-use. Its documentation is far more comprehensive than its competition. Despite CCXT’s advanced features, mastery of the platform is more complex and take longer than Vezgo’s.
CCTX is very great for traders. Developers and traders who use CCXT’s APIs for trading purposes will be making the most use of the software’s functionalities. On the other hand, Vezgo is a lot more suited for portfolio trackers, financial dashboards, and wealth management apps.
CCXT is a powerful tool, as it packs several functions. However, Vezgo positions itself as a solid CCXT alternative and slightly edges it out regarding data distribution and storage, user management, backtesting, and scalability.
So which one fits what you’re building?
The clean way to decide is to ask what your application does to an exchange, not what it reads from one.
- You’re building a trading bot, market-making tool, or backtesting engine: Use CCXT. You need execution, live order books, and low-latency access, and none of that is Vezgo’s job. The maintenance cost is real, but it buys you control over exactly the surface you care about.
- You’re building a portfolio tracker or net-worth app: Use Vezgo. Your users hold assets on exchanges, in self-custody wallets, and across chains, and stitching that into one view is the entire product. Doing it with a trading library means writing the wallet and chain layer yourself.
- You’re building tax or accounting software: Use Vezgo. Tax output depends on complete, normalized transaction history, including the awkward stuff: transfers between a user’s own accounts, staking rewards, and internal movements. Reconciling those from raw exchange responses is where these projects go over schedule.
- You’re building a wealth management or advisor dashboard: Use Vezgo. Beyond the data, the audited security posture and read-only access model are usually what gets you through the client’s vendor review.
- You need broad market data for research: CCXT is a reasonable free starting point, though at serious volume, a dedicated market data provider will serve you better than either option here.
Can you use both?
Frequently, yes, and it’s a sensible architecture rather than a compromise.
A trading platform might use CCXT for the execution path and live market data, while using Vezgo to aggregate the read-only account data its users connect from exchanges and wallets they hold elsewhere. The two jobs have different failure modes, different security requirements, and different maintenance profiles. Treating them as one problem is what makes them hard.
If you’re already deep into a CCXT build and only the aggregation side is hurting, you don’t need to rip anything out. Adding Vezgo alongside it for balances, history, and wallets is usually a smaller change than the migration you’re imagining.
Verdict: CCXT Vs. Vezgo
CCXT is a fantastic tool for any developer. It boasts integrations with over a hundred crypto exchanges and APIs to its credit. It’s available in three popular programming languages and is regularly maintained by a dedicated technical team.
However, anyone new to crypto exchange APIs might find Vezgo the more appealing choice due to its ease of use and near-unrivaled data accessing features.
