t3a.large (8 GiB) or larger — the all-in-one deployment runs its database and cache on the instance
Production stack
Drag-and-drop UI builder with JavaScript anywhere, behind automatic TLS; connectors for popular SQL and NoSQL databases and REST or GraphQL APIs; persistent data volume; UFW firewall and unattended security updates on a hardened Ubuntu 24.04 base
Per-seat low-code vs self-hosted: the real cost
Pricing verified June 2026 against retool.com and AWS us-east-1 rates.
Hosted low-code platforms like Retool bill per builder and per internal user, every month — so the cost climbs with every person who touches a tool. The appliance runs the open-source Appsmith Community Edition: flat infrastructure cost, unlimited builders and users, in your own account.
| Option | Price | Scales by | Data lives in |
|---|---|---|---|
| Retool Team | $10/builder + $5/user/mo | Per seat | Vendor cloud |
| Retool Business | $50/builder + $15/user/mo | Per seat | Vendor cloud |
| AppXen App Builder | ~$108/mo flat | Unlimited seats | Your AWS account |
Retool prices shown at annual billing (a "builder" is anyone who edits an app that cycle). Appliance all-in = $0.075/hr software (≈ $54/mo) + a t3a.large (≈ $54/mo) + EBS, flat regardless of how many people build or use your apps.
Cost scenarios
Tiny team · 1-2 builders
A hosted Team plan can be cheaper to start (Retool's free tier covers up to 5 users). The appliance pulls ahead once you add builders, add internal users, or want everything in your own account.
Growing team · 5 builders + 20 users on Business
That's 5 × $50 + 20 × $15 = about $550/mo, climbing with every hire. The appliance is ~$108/mo flat with unlimited builders and users — roughly $5,000/year saved.
Own your tools and data
Your apps, data sources, and the databases they query live in your AWS account and region — never on a platform that can reprice or restrict you.
When a hosted platform is the better choice
Pick a hosted plan for its polished managed cloud, premium support, and advanced governance, if you have only a builder or two, or if you'd rather not run an instance. The appliance wins on flat cost at team scale, unlimited seats, and full ownership of your tools and data.
Getting started
Launch on a t3a.large or larger with ports 80, 443, and 22 open, wait about 3 minutes for first boot, then browse https://<public-ip>/ and create your account — the first account you create becomes the instance administrator. For a trusted certificate, point a domain you own at the instance and launch with the EC2 user-data line APPLIANCE_DOMAIN=yourdomain.com.
