What our research says

AppIsUp

AppIsUp is a small VPS with Claude Code already running on it: what the agent builds is live on a public URL the moment it is written, and you talk to it from a browser or a phone. That suits a developer who already pays for an Anthropic key and wants a sandbox server without setting one up; it is a poor fit for anyone who needs a staged deploy process or a vendor with a public legal identity.

Pros

Flat server price with no credit system; the AI bill goes to your own key
Every app gets a public URL with SSL automatically, and custom domains cost nothing extra
Root access inside your own container, so any language or tool can be installed
Choice of cloud provider and region

Cons

Edits go live instantly, so there is no separation between working copy and production
Small instances: the top published plan is 2 CPU and 2 GB of RAM
No terms of service, privacy policy or operating company found on the site

Replit

Still the most complete build-and-ship-from-a-browser setup, and the new credit-free Free Mode makes everyday iteration cheaper than it was. The bill is still set by the agent, though: anything that needs the stronger models draws on a $20 balance on Core and then runs pay-as-you-go by effort.

Pros

Editor, agent, database, storage and publishing in one browser workspace
Free Mode allowance refreshes every few hours on paid plans, so routine chat does not burn credits
Annual billing trims Core to $18 and Pro to $90
iOS and Android apps for checking and nudging builds on the go

Cons

Effort-based overage makes the bill unknowable in advance
Core's $20 of model credits goes quickly on agent-heavy work
The free Starter plan has dropped off the pricing page, so the free path is harder to judge
No public API found for driving the agent programmatically
