Base44 vs Capacity

Base44

• Non-developers building internal tools, portals or back-office apps
• Builders who want database, login and hosting handled in one product
• Students and teachers, who can verify a school email for half-price plans

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

Base44

• The Free plan is limited to 25 message credits a month and 5 apps.
• GitHub integration, AI model selection and app-store files all start on the Builder plan.
• Listed prices assume annual billing; the pricing page says yearly billing is 20% cheaper than monthly.
• Connecting a domain and managing app security are not available when editing on a mobile device.

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.

Base44

Prompt-to-app building

Describe an app in plain language and Base44 generates the frontend, backend, database and login. A typical message uses roughly 0.5 to 4 credits depending on scope.

Built-in backend and services

Every plan includes a database, authentication and user management, cloud storage and analytics. Built-in services such as email and image generation draw on integration credits.

Visual editor

A responsive visual editor handles layout and text changes directly. Manual edits such as dragging elements or editing text do not use credits.

Connectors and integrations

One-click connectors cover Salesforce, Notion, Slack, HubSpot, Gmail and Google Workspace apps, with manual API integrations for tools such as Twilio and Zapier.

Code access and GitHub sync

Paid plans allow in-app code edits, and two-way GitHub sync, listed from the Builder plan, exports the full source code to your own repository.

Mobile apps and store files

Base44 has iOS and Android apps for building on the go, and the editor can generate the IPA and AAB files needed for the App Store and Google Play on Builder or higher.

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.
