TL;DR
Coinglass is the most comprehensive crypto derivatives data provider on the market and the right choice if you need a broad surface (liquidations, ETF flows, on-chain data, options, more). Funding Finder is a niche-focused alternative that does only cross-exchange funding-rate arbitrage, costs 5-6x less, and is open-source-friendly. Both are valid. Pick based on what you actually need.
Funding Finder ships with: 20 perpetual futures exchanges (~6,800 USDT-margined symbols), free tier with no signup, an autonomous hourly signals feed, an autonomous daily research blog, 10 free trader calculators, downloadable OSS data collector under MIT, and a single-glance ★ Now dashboard. Pricing starts at €5/mo.
If you spend <25% of your Coinglass usage on funding-rate data, stay on Coinglass. If you spend >75% of your usage on funding-rate data, Funding Finder will save you about $24-25 per month — or $0 if the free tier covers your needs.

The Trader tier on Funding Finder is roughly 1/6 the price of the Hobbyist tier on Coinglass while delivering 20x the rate limit on a narrower data surface. If your use case is funding-rate arbitrage or sentiment monitoring, the math is straightforward. If you need the broader Coinglass surface, the math is the opposite.
When you should pick Coinglass
- You use liquidations, ETF flows, OI, and on-chain metrics regularly
- You need 30+ exchanges of funding-rate coverage including the very long tail (Funding Finder covers the 20 most liquid)
- You're comfortable with $29/mo+ and want a single-vendor relationship
- You prefer a more polished UI and broader feature surface
- You don't want to deal with multiple specialized data tools
When you should pick Funding Finder
- You spend most of your data time on cross-exchange funding-rate arbitrage
- You want the data layer to be open source and self-hostable (free download, MIT)
- The €5/mo entry tier is meaningfully friendlier to your budget than $29/mo
- You need the slippage-aware net APY computation built into the API
- You want stddev-based divergence ranking with persistence filter (not just spread-based)
- You want autonomous push: an hourly signals feed, a daily research post — not just a dashboard you have to check
- You want free trader calculators built in (funding fee, liquidation, Kelly, position sizing, etc.)
- You appreciate that the tool does one thing well rather than many things broadly
- You want a no-signup free tier for casual exploration
An honest disclaimer
I built Funding Finder. I am not neutral. But I also subscribe to Coinglass and have for over a year — it's a great product for what it does, and I built Funding Finder because I wanted a focused alternative for one specific use case, not because Coinglass is bad. This page is intended to help you make the right decision for your workflow, not to dunk on the competition.
Verdict
If you're a retail trader or small quant team focused on funding-rate arbitrage and you find Coinglass's $29/mo entry plan painful, give Funding Finder's free tier a try. The free tier is genuinely free forever (no signup, no email) and covers 95% of what most traders need: 20 exchanges, ~6,800 perpetual symbols, divergence scanner, autonomous signals feed, daily research, 10 calculators. If you upgrade later, €5/month gets you the API access and history that the Hobbyist tier on Coinglass provides at 6x the price.
