Cielo vs Nansen in 2026: Costs, Alerts or Labels
VS
Last verified: October 29, 2026 (Nansen's homepage and fee ladder re-read). Nansen's full fee ladder read on its official pricing page on October 11; Cielo's Arc support added from its post of September 22. Both buttons at the bottom are referral links, marked. Both tools have a free tier, which is the no-risk way to decide between them.
The one-rule answer: Cielo if you want to know when a wallet moves. Nansen if you want to know who the wallet is.
Cielo pushes real-time alerts into Telegram and lets a tracked buy become your own trade inside the same product, at 0.6% by hand or 1% through an agent.
Nansen answers the question Cielo cannot: whether that address belongs to a fund, an exchange or a proven trader. Since January 2026 it also trades, at 0.75% on the entry tier, falling to 0.10% at the top of its points ladder.
They are not really rivals. Plenty of people run Cielo free for alerts and pay Nansen only when they need the labels.

Where Cielo wins
Speed of reaction, and price. The free tier tracks 250 wallets, which is more than most people will ever watch seriously, and the alerts arrive where you already are rather than in a dashboard you have to remember to open.
Then it closes the loop: a wallet you track buys something, and you can act on it in the same product, at 0.6% by hand, the cheapest manual fee of any tracker on this site, or 1% through an agent.
The full review covers the agent controls, the filters and the one thing Cielo still does not document.
Where Nansen wins
Knowing what you are looking at. An address that just bought is only a signal if you know something about it, and that is the entire Nansen product: labels built over years, across 37 chains.
At $49 a month on the annual plan it is no longer a fund-only tool.

Most competitor reviews still quote the old higher tiers, so check the current pricing page rather than the blogs.
Its chain dashboard is also the fastest way to see where volume actually is: on September 5, 2026 it put Robinhood Chain first of all chains for fees over seven days, which is the kind of thing you want to know before choosing what to track.
The custody difference, spelled out
Both now let you trade, and that changes the risk conversation. Tracking a wallet costs you nothing but a subscription. Funding a trading wallet inside a product is a different decision.
Nansen answers it plainly: the wallet is embedded, there is a View Private Key button, and MFA is available. If the company disappeared tomorrow, you could still open that wallet elsewhere.
Cielo answered on September 14, 2026, publicly on X: its embedded wallets use Turnkey for key management, and its docs describe an export of the private key. The rule stays the same on both: keep only what you actively trade in there.

So both now answer the question. We had written that Cielo did not; it did, and we missed it.
What most people actually do
Run Cielo's free tier for the alerts, because 250 wallets and Telegram notifications cost nothing. Add Nansen when a specific question comes up that alerts cannot answer, which is usually "is this wallet somebody, or is it noise".
If you only ever pay for one, pay for the one that matches your bottleneck: reacting fast, or knowing who you are copying. The full trackers comparison puts both against Arkham, GMGN and the free stack.
FAQ
Is Cielo or Nansen better for copy trading?
Cielo, because the alert and the trade live in the same product; count 1% on agent-executed trades, 0.6% by hand. Nansen is built for research first and added trading in 2026.
For copy trading beyond trackers entirely, the copy trading comparison covers the apps built for it.
Is the Nansen free tier enough?
Enough to see the interface and decide, not enough to work with. The labels are the product, and the depth of what you can see is what the subscription buys.
Do I need both?
No. They answer different questions, and a lot of people run Cielo free alongside a paid Nansen rather than paying for two.
Which one is cheaper to trade with?
Cielo at 0.6% on manual trades, 1% on agent trades. Nansen starts at 0.75% and only goes below Cielo from its third points tier (0.25%), down to 0.10% at the top; its perps add a builder fee of 0.08% to 0.01% on top of Hyperliquid's own fee.
That is a real difference for anyone trading size, and no difference at all for someone tracking wallets and buying occasionally.
Links
(ref links) Both are referral links: we may earn a share of fees or subscriptions at no extra cost to you. Both have free tiers, so you can decide before paying anyone anything. For Cielo, create the account on the web first, then connect Telegram from inside the app; the bot alone carries no referral.
New tools the week they launch. The settings and fees that quietly cost you money. Alpha I would tell a friend.
