5 Free Crypto Analysis Tools: From Price Tracking to On-Chain Data

When I first started seriously researching crypto last year, the first thing I did wasn’t opening an exchange account—it was finding tools.

Because I knew one thing clearly: in this market, information gap is money gap. If you know ten minutes earlier that a coin’s RSI is oversold, a DeFi protocol’s TVL has suddenly spiked, or a chain’s active addresses hit a new high—those could all be opportunities. But if your analysis method is “open the exchange, stare at the K-line chart and zone out”—honestly, that’s basically just guessing.

So I spent a lot of time testing various tools. Paid ones, free ones alike. Later I found that a combination of free tools is already more than enough—at least for most investors.

This article covers the 5 free tools I use daily, each solving different problems.

1. CoinGecko: Your Crypto Market Dashboard

If I could only pick one tool, it’d be CoinGecko.

It’s one of the most comprehensive free crypto data platforms out there, tracking real-time prices, market caps, and trading volumes of over 14,000 cryptocurrencies. But what makes it truly useful isn’t just the data volume—it’s how it organizes the information.

My most-used features:

• Trending coins tracking (no need to search manually)
• Exchange rankings and liquidity scores
• Historical price charts (free version shows years of data)
• Free API for connecting to your own tools

CoinGecko’s role is more like “the first thing I open every day.” Understanding what the market’s doing, which coins are moving, where market sentiment roughly stands. It won’t tell you what to buy, but it helps you build a complete picture of the current market.

2. TradingView: The Standard Tool for Technical Analysis

I know when people hear “technical analysis,” it sounds like voodoo. But to put it simply, technical analysis is using patterns in historical prices to judge what might happen next. It’s not foolproof, but it provides a framework for analysis—way better than just going by gut feeling.

TradingView is the most widely used charting and analysis platform. The free version offers over 40 technical indicators—RSI, MACD, Bollinger Bands, EMA—basically all the basics.

What the free version can do:

• K-line charts with multiple timeframes
• Draw trendlines, support and resistance
• Basic price alerts
• Browse community analysis ideas (some are really good)

Though the free version has a limitation: limited chart storage (around 5), and real-time data has a十几 minute delay. If you’re not doing ultra-short-term trading, this delay doesn’t really matter.

3. DeFi Llama: The Window into DeFi

If you’re involved with DeFi, DeFi Llama is a must-have tool, and it’s completely free.

DeFi Llama tracks Total Value Locked (TVL) across all major DeFi protocols, covering dozens of chains and thousands of protocols. Why does TVL matter? Because it’s the metric for how much actual money is running through a DeFi protocol. A TVL crash usually means capital is fleeing, while steady TVL growth means confidence is building.

What I look at:

• TVL rankings and trends by chain
• Historical TVL for individual protocols
• Yield comparisons (where’s the better APY)
• Cross-chain fund flows

One thing I really appreciate about DeFi Llama: no registration needed, just open and use. And their API is also free—if you’ve got the technical skills, you can build your own analysis with it.

4. Dune Analytics: Free Exploration of On-Chain Data

Dune Analytics is different from the other tools. It’s more like an on-chain data query platform—you can use SQL to query any public data on Ethereum, Polygon, Arbitrum, and other blockchains.

Sounds super techy, but you don’t need to write SQL yourself. There are thousands of community-made public dashboards on Dune—just browse them. Like someone made a Uniswap volume tracker, someone made whale wallet monitoring, someone made NFT market heat analysis.

What the free version offers:

• Browse all public dashboards
• Fork others’ queries to modify
• Create basic data queries and charts

The limitation is the free version has slower query speed and execution limits. But if you just want to know what’s happening on-chain, the community dashboards are already enough.

5. CoinSifter: The Open Source Tool That Auto-Screens Coins for You

The first four tools are great, but they all share one problem: you have to find the information yourself. You have to click through coins one by one on CoinGecko, draw your own charts and set conditions on TradingView, DeFi Llama and Dune also require you to actively query.

CoinSifter solves a different problem: if I already know what conditions I’m looking for, can the tool automatically scan for me?

It’s an open-source crypto screener—you set your technical conditions, like “RSI below 30 AND EMA golden cross AND daily volume above X threshold”—and it automatically scans all trading pairs on Binance, listing coins that match.

What it can do:

• 8 technical indicator filters (RSI, EMA, MACD, Bollinger Bands, KD, etc.)
• Scan multiple timeframes simultaneously (4H, 1H, 15m, 1D)
• Save screening strategies in YAML, switch anytime
• Auto-push notifications via Telegram when matches are found
• Has a web interface—no need to touch the terminal

My favorite way to use it is setting up conditions and letting it run on schedule. Like scan every 4 hours, push a notification to my phone when there’s a match. No need to stare at the screen all day, won’t miss any opportunities that fit my criteria.

And it’s MIT licensed, completely free, all code on GitHub.

How to Combine Them?

These five tools each cover different areas:

My daily flow usually goes like this: CoinSifter runs in the background, notifies me when there’s a match. When I get a notification, I first check basic data on CoinGecko, then open TradingView to confirm the technicals. If it’s DeFi-related, I check DeFi Llama for any TVL anomalies.

I don’t go through the full process for every opportunity. But with these tools, at least every decision I make is backed by data—not just pure gambling.

Final Thoughts

The crypto market moves fast, but good analysis tools let you see structure in the chaos. All five tools are free and don’t require any technical background to get started.

Start with CoinGecko to get familiar with the market, then slowly add other tools. You don’t have to learn everything at once—pick up each tool as you need it.

The point isn’t the tools themselves—it’s whether you’re using them to make better decisions.
