STACK SCORE
88
Mean of the role winners, compatibility +4. Separate from each tool score.
Provisional seed scores. Method seed-v0-provisional, confidence low, not hands-on tested. The band around a number is a ±8 display label, not a measured interval. Ordering uses the point estimate.
We may earn a commission if a tracking link is connected and you buy through it. It never changes ranks. In this v1 seed, tracking URLs are empty, so “Open site” goes to the vendor. Sponsorship rules.
Recommended stack
Host long-running agents and backends with durable jobs, a database, and traces.
Example compatibility note, not a measured integration test. Trigger.dev and Inngest run alongside Railway, Render, or Vercel.
ROLE
Durable jobs
Retries, schedules, and steps that survive crashes.

Questions
Are these scores from hands-on tests?
No. Every score on this page is a provisional seed estimate with low confidence. The band around the number is a display convention, not a measured interval.
Can a paid listing change who is recommended?
No. Affiliate programs and sponsored cards are not inputs. A sponsored card, when one exists, is labeled and sits outside the ranking.
