Capacity vs Replit

Capacity

• Non-developers who want an app built and hosted in one place
• People who already pay for Claude or ChatGPT and want to build with it
• Products that need a web app and a companion mobile app on one backend

Replit

• People who want an app built, hosted and published in one place
• Builders who expect to read or edit the code in a full cloud workspace
• Small teams sharing one plan: Core covers 5 builders and Pro 15, with no per-user fee

Capacity

• The pricing page lists no free plan; paid plans start at $25 a month, and extra credits are sold from $9 for 10.
• The built-in agent is metered in credits, and each message uses a variable amount depending on the task.
• Servers larger than the free 256 MB tier draw 1 to 10 credits a day from the same balance.
• The desktop app is described as a Mac app; no Windows or Linux version is mentioned.

Replit

• Starter is limited to Lite build with daily caps, and its single published app goes offline after 30 days.
• Connectors, Plan Mode, full build and Replit AI Integrations all require Core or Pro.
• Power and Max mode work is billed by effort from monthly credits, and usage beyond them is pay-as-you-go.
• The mobile app is for building websites and web apps; native iOS app projects have to be started on the web.

Capacity

Questions first, then a full-stack app

Capacity asks about purpose, users and style before it builds, then generates a frontend, a backend and a dedicated database that are wired together.

Build from Claude or ChatGPT

A connector lets Claude or ChatGPT create and edit Capacity apps from a chat. That work runs on your own AI subscription and uses no Capacity credits on paid plans.

Vibe and Spec coding modes

Vibe mode builds straight from prompts. Spec mode has the AI follow a project brief, UX specs and design requirements that are written first.

Hosting and custom domains

Apps publish to a capacity.studio address on a dedicated server. The 256 MB tier uses no credits, larger servers use 1 to 10 credits a day, and custom domains can be connected.

Native mobile apps

A project can include an iOS and Android app built with Expo that shares the web app's backend. Builds run in the cloud and can be submitted to both app stores.

Version history and code export

Every change is a version that can be restored. The pricing page lists full codebase export under Growth, while the changelog says ZIP download is on all plans.

Replit

Agent with Free, Power and Max modes

Agent builds, debugs and iterates on an app from chat. Free Mode costs no credits within a plan allowance; Power and Max use monthly credits and need Core or Pro.

Built-in database, storage and auth

Replit-managed integrations include a PostgreSQL database, App Storage for files, Replit Auth sign-in and custom domains, with no API keys to set up.

One-click publishing

Apps publish to a live URL from the workspace. Starter includes 1 published app for 30 days; Core and Pro allow unlimited apps and remove the Made with Replit badge.

Design Canvas and Visual Editor

Design Canvas explores visual ideas and variations, and the Visual Editor changes content and layout directly. Converting a design into a full app needs Core.

Connectors

Sign in once to services such as Google Drive, Gmail, GitHub, Linear and Jira, and Agent can read and write to them from chat. Most connectors need a paid plan.

Web, mobile and other artifacts

Agent builds web apps and native iOS and Android apps with Expo previews. Core and Pro add slide decks, data visualizations, animated videos and other artifact types.
