Coinlib Is a Crypto Data Aggregator with Built-In Portfolio Tracking
Coinlib is one of those platforms that quietly does the job. It aggregates prices, charts, and volume from multiple exchanges and lets users compare data in real time. But it goes further than a typical tracker - it also offers personal portfolio tools and custom alerts. All without asking for registration.
What You See on the Homepage
The homepage is dense but clear. It lists coins by market cap with sortable columns: price, 24h change, volume, 7-day chart. You can filter by exchange, fiat currency, or coin type. Click any asset to dive into its live chart, full order book (aggregated), and market list. Everything updates in real time.
There’s no fluff. No blogs. No signup pop-ups. It’s built for users who want data, not hype.
Price Comparison Tool
One of the standout features is price comparison. Coinlib shows how much a coin trades for on different exchanges - with spread data included. For arbitrage hunters or cross-platform traders, this is gold. You don’t need to open tabs on Binance, Kraken, and Coinbase - it’s all in one place.
You can also simulate trades between coins and currencies using a built-in calculator. It’s fast and updates instantly with live rates.
Portfolio Tracking Without Registration
Coinlib allows you to track your crypto holdings anonymously. You can add transactions manually - coin, amount, buy price - and the site calculates P&L, portfolio allocation, and average cost. All data is stored locally in your browser unless you choose to export.
This makes it ideal for users who don’t want to share data or link wallets. It’s also quick to use - no logins, no verification, just paste in your numbers and watch your balance move.
Alerts, Heatmaps, and More
You can set price alerts for any coin or pair. When a threshold is hit, you get a browser notification (if enabled). There’s also a heatmap view for scanning price changes visually - useful when watching dozens of assets.
Other features include:
- Trending coins based on volume and price action
- Exchange listings by liquidity
- Market dominance data by sector or asset type
Mobile Access and Speed
The site is fully responsive and works well on mobile. Charts remain interactive, and filters are preserved. Because it’s lightweight, Coinlib loads fast even on older devices or low-bandwidth connections.
There’s no mobile app, but the web version acts like one. You can pin it to your home screen and use it offline for previously loaded data.
Weak Points
It’s not perfect. The platform doesn’t support API sync with wallets or exchanges. That means no automatic portfolio updates. Also, while it’s fast, some niche coins are missing or delayed.
And there’s no dark mode - the bright layout may not suit all users.
Who Should Use Coinlib?
If you want quick access to price data and a lightweight way to track your holdings, Coinlib delivers. It won’t replace a trading terminal, but it’s a solid companion for daily tracking - especially for people who value speed, simplicity, and privacy.
