On the prices each vendor publishes about itself, Devin starts at Free, then $20 / mo and Jules at Not read. Neither takes your own API key, both bundle model usage, and on both the headline price is an allowance rather than a bill. Every figure on this page was read from the two vendors' own pages in last night's run rather than written down once, which is the only reason it is still the current answer. ToolDrift sells neither and takes no referral fee on either.

Is Devin or Jules cheaper?
On the cheapest option each vendor publishes: Devin is Free, then $20 / mo and Jules is Not read. Treat both as an allowance rather than a bill, every tool in this category meters model usage on top of the plan, and which one costs more in practice depends on the models you drive and how hard. The tier prices are the part that can be checked from outside, so they are the part this page prints.
Can I use my own API key with Devin or Jules?
Devin: no, model usage is bundled. Jules: no, model usage is bundled. It is the row that decides whether the subscription price is most of what you pay or a fraction of it: a tool that takes your own key charges for the software, and one that does not is reselling inference with a margin you cannot see.
Are Devin and Jules still maintained?
Active and Active as of last night's read. Devin publishes no repository this site tracks, so there is no push date to read; Jules publishes no repository this site tracks, so there is no push date to read. This is the question a written comparison cannot answer, because it was true on the day it was published and nobody went back.
