# Query Dojo vs Upstream

Query Dojo and Upstream are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Query Dojo sells 2 in-app purchases, starting at $7.95 per month and Upstream sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Query Dojo ships an update every 2 weeks, Upstream every 11 days. The most recent releases landed on September 19, 2026 and September 17, 2026 respectively.
