Uno vs Jumpstart Pro
Two commercial Rails SaaS templates, two different bets. This page is written by Uno's author — biased by definition — so it sticks to facts you can verify on jumpstartrails.com and says plainly when Jumpstart Pro is the better choice.
| Uno | Jumpstart Pro | |
|---|---|---|
| Pricing model | One-time purchase ($199/$249), 12 months of updates, lifetime access to every version you download | Subscription: $249/yr (single site) or $749/yr (unlimited apps); cancelling ends access to updates |
| License scope | Unlimited personal and commercial projects | Single Site licence covers 1 application; Unlimited tier covers any number |
| View layer | Phlex 2 — views are pure Ruby objects | ERB with Hotwire (Turbo + Stimulus) |
| Runtime dependencies | PostgreSQL only — jobs, cache, websockets, events all on Postgres; no Redis, no Node in production | Redis optional: Solid Queue by default, Sidekiq (Redis) available; esbuild for JS |
| Payments | Stripe (checkout, portal, webhooks, one-time + subscriptions) | Stripe, Paddle, Braintree, PayPal — widest processor coverage |
| Teams / multitenancy | Single-account model out of the box | First-class teams and multitenancy |
| AI-agent readiness | Built for it: AGENTS.md, 40+ per-feature docs, agent-legible pure-Ruby views, N+1 guard failing the build | No AI-agent positioning or tooling as of July 2026 |
| Event sourcing / audit | Rails Event Store — every state change recorded and replayable | Not included |
| Mobile | Hotwire Native iOS shell + installable PWA included | Companion iOS/Android templates sold separately ($199/$599 per year) |
| Deploy | Kamal 2 + Docker + Thruster to any VPS, wired | Deploy-agnostic; devcontainer/Docker option |
| Maturity & community | Newer product, one maintainer, updates driven by production apps | Years of releases, GoRails brand, customer forum, screencasts |

Choose Jumpstart Pro if…
- You need teams and multitenancy on day one — it's first-class there and not in Uno.
- You need Paddle, Braintree, or PayPal — Uno is Stripe-only.
- You want the safety of a long track record, a customer forum, and the GoRails ecosystem.
- An annual subscription for continuous updates fits how you budget.
Choose Uno if…
- You build with AI coding agents — AGENTS.md, 40+ per-feature docs, and pure-Ruby views exist exactly for that.
- You want one server and one datastore: PostgreSQL runs jobs, cache, websockets, and events. No Redis to operate.
- You prefer paying once over renting: one payment, 12 months of updates, unlimited projects.
- You want event sourcing and a full audit trail without wiring it yourself.
Why does the pricing model matter?
Jumpstart Pro is a subscription: $249 or $749 every year, and cancelling ends your access to updates. That is a reasonable trade — continuous maintenance costs money — but it is a recurring cost per year, per licence tier. Uno is a one-time purchase with 12 months of new releases included; everything you have downloaded keeps working and stays licensed forever. Neither model is universally better: a funded team shipping many apps may prefer Jumpstart's unlimited subscription; a bootstrapper who wants a known, one-off cost usually prefers Uno's.
What does "built for AI agents" change in practice?
Jumpstart Pro is a mature template built for human developers, and as of July 2026 it has no AI-agent tooling or positioning. Uno is structured so a coding agent can work in it reliably: AGENTS.md defines the rules, every feature has its own doc the agent reads before touching code, views are plain Ruby objects (no template dialect to mis-edit, fewer tokens to burn), and the test suite plus an N+1 guard fail the build before agent slop ships. If Claude Code or Cursor writes a large share of your code, this is the practical difference between the two.
Who wins on runtime simplicity?
Both can run without Redis — Jumpstart Pro defaults to Solid Queue and keeps Sidekiq as an option, Uno never introduces Redis at all. The difference is scope: Uno commits to PostgreSQL as the only datastore for jobs, cache, websockets, and its event store, and its deploy story (Kamal 2 to a $6 VPS) is wired end to end. Jumpstart Pro leaves deployment to you, which is flexibility or homework depending on your team.
