How we know
Every row that separated these two, and where it came from. Nothing here is a hands-on test — if a line rests on a vendor’s own pricing page, it says so and links it.
| Row | Favours | Weight | Where it came from |
|---|---|---|---|
| What it's built for | Julius AI | How well it does the job | From this site’s own catalogue record for each product — compiled by hand, not imported. How a product gets listed |
| Fit for coding, data & technical work | Julius AI | How well it does the job | Both products are listed under coding, data & technical work in the catalogue, and this is the fit recorded against each listing. Everything listed under coding, data & technical work |
The prices
Devin. Read by hand on 4 September 2026, because Devin cannot be read automatically: devin.ai answers 429 to automation on every run; the docs carried no prices. Verify by hand. devin.ai/pricing
Julius AI. Read by hand on 4 September 2026, because Julius AI cannot be read automatically: julius.ai refuses automation (403) and the help-centre alternate carries no prices. Three refusals across runs 14, 16 and 23 — that is a policy, not luck. Verify by hand: the ladder was read off the in-app subscription page, both billing toggles. julius.ai/pricing
The ratings
The category these two share. Coding, Data & Technical Work — both are listed there in the catalogue, and the fit recorded against each listing is a judgement made here, by hand.
The nine-category grid below. Derived from what each product is listed for, by one script, once per build — so the same pair always reads the same. It is a derivation, not a review.
What this is not
Neither product was run side by side to produce this page. Nobody was paid to appear on it and nothing here is ranked by commission.
To put the same question to both and read the answers yourself, run them side by side — that is a live test, and this is not.
Choose based on what you’re doing
All ten categories, including the ones where neither of these is the answer. These ratings are derived from what each product is listed for, not from running it — a rating here is a reading of the record, and the record is linked.
