Replit Agent 4 and mobile deployment
Replit Agent 4 builds full applications from natural language prompts using a task-based workflow. This version includes Canvas, which provides an infinite board for sketching ideas, and multi-artifact projects that contain a web app, a mobile app, and a pitch deck within a single project. For React Native teams, the platform supports mobile-app artifacts through Expo. You can preview these apps in an iOS Simulator or an Android Emulator directly inside the Project Editor or use Expo Go on a real phone. The Agent 4 workflow manages the entire lifecycle from scaffolding to app store submission.
The platform includes built-in storage and a database to power live apps. The Agent 4 also connects to services like Notion and Linear to assist with project management. The platform provides a real-time visual preview of app development. The Agent also includes a checkpoint system that allows users to roll back to previous versions easily.

Pricing tiers and credit usage
Replit uses a hybrid pricing model that combines fixed subscriptions with effort-based billing for AI and compute resources. Users pay for their subscription to unlock the workspace, then use credits for AI prompts, agent runs, compute, and deployments. When you run out of monthly credits, Replit switches to pay-as-you-go billing. This model causes frustration because the Agent bills credits based on task complexity, which makes costs unpredictable. One user reported charges of $42 on the first day of a $20 subscription after the agent ran complex tasks. If you already understand how Git integration works, the Replit interface feels like a natural extension of your current workflow.
| Plan | Monthly Price | Annual Price | Key Feature |
|---|---|---|---|
| Starter | $0 | $0 | 1 published app |
| Core | $20 | $18 | 5 collaborators |
| Pro | $100 | $90 | 15 builders |
| Enterprise | Custom | Custom | SSO and custom support |
The Core plan provides $20 in monthly credits, 4 vCPUs, 8 GiB of memory, and 50 GiB of storage per app, but unused credits do not roll over. The Pro plan includes $100 in monthly credits, 8 vCPUs, 16 GiB of memory, and 256 GiB of storage per app, and these credits roll over for one month. The Pro plan also supports up to 15 builders and provides 28-day database rollbacks. Users can also access Free Mode, powered by OpenAI’s GPT-5.6 Luna, to create 30X more than before. This mode allows core subscribers to create more for just the cost of their monthly subscription, as daily tasks no longer use credits. For more intensive tasks, the Agent may suggest switching to Power Mode, which uses cost-optimized models, or Max Mode, which uses higher-performance models for deeper reasoning. GitHub Copilot serves as an alternative for developers wanting lightweight, zero-configuration autocomplete inside an existing IDE. Replit differs by offering a full-stack environment that builds applications from scratch with database provisioning in minutes. AppGenie targets non-technical founders with a chat-first builder UX, while Replit targets developers with an IDE-first platform.
Developer workflow and alternatives
Replit remains the superior choice for developers who want a full cloud IDE with integrated hosting and databases. The platform combines a code editor, runtime, and AI agent into one workspace, making it a powerful choice for engineers who need to manage their entire development lifecycle within a single browser tab without setting up local environments. However, the interface favors technical builders and requires familiarity with repositories and consoles. The Agent often introduces bugs while attempting to fix other issues. Developers must monitor their usage dashboard to prevent the high costs that come from unexpected agent retries.
Users building mobile apps can choose between Replit’s IDE-centric model and AppGenie’s chat-first builder UX. Replit provides a native mobile build path with Expo, simulator preview, and Expo Go testing. AppGenie targets a narrower product model. For teams needing advanced features like real-time editing and shared terminals, Cursor or GitHub Codespaces provide stronger collaboration and workflows. For rapid full-stack generation and deployment, Bolt provides fast scaffolding.
