Pick it when
Pick Rotki if API key blast radius matters most — it scores 9/10 to Delta's 8/10 there (weight 30).

Tradeoff
The free tier's 1,000-event ceiling bites fast for an active trader — real history and PnL effectively cost 25 EUR/mo (Basic), since the 9 EUR Supporter tier keeps the 3K-event cap but withholds graphs and event analysis — and self-hosting means you install, update and troubleshoot the app yourself; margin and futures trades don't sync at all.

Pick it when
Delta leads Rotki on no published criterion and no score dimension — pick it only if a fact outside the score (country, funding rail, custody) decides for you.
Strength
Api key blast radius — 8/10
Tradeoff
The free tier is effectively a demo for this buyer: two total connections and ten tracked assets means anyone with a couple of exchanges plus a wallet pays $6.99/mo almost immediately — and while your API keys stay on your phone, your synced trades and balances sit on eToro-group servers under the broker parent's group privacy policy, which grants eToro broad rights to market to you and to share pseudonymised details with ad platforms.

Score dimensions
weights sum to 86
The published score is five dimensions, each weighted for the category. "Published criteria" is the criteria block above; the other four are the engine's own terms — availability, friction, trust record, measured data. Each bar is one side's points out of that dimension's maximum; the weight beside the name is its points of the 86-point weighted total. The published criteria above can fill 24 of the block’s 30. A weight marked “constant here” belongs to a dimension every ranked product in the category holds at the same value: it still counts in the total, and it orders nothing here.
