Serverless cloud infrastructure for AI and data workloads
Write plain Python, attach GPUs or containers, and deploy HTTPS endpoints that autoscale with traffic and scale to zero when idle.
Launch isolated, secure environments for coding agents, RL rollouts, and untrusted code, with sub-second starts and support for over a million concurrent sandboxes.
Run fine-tunes, LoRA, full training, and reinforcement learning on elastic single or multi-node GPU capacity with no quota requests.
Serve LLMs and image, video, or audio models through OpenAI-compatible endpoints, or bring your own inference stack and let Modal handle the infrastructure.

Describe your idea and Replit builds a working app in minutes
Describe the product you want and the agent plans, codes, tests and iterates on a working full-stack application.
Authentication, databases, hosting and monitoring work out of the box, so apps scale without separate DevOps work.
A no-cost mode lets you brainstorm and build without spending tokens before upgrading to stronger models.
Connect services such as OpenAI, Stripe and Google Workspace in minutes rather than writing glue code.
Delivers exceptional UI generation and full-stack app creation, but focuses less on traditional multi-language code editing than Replit.
#1
Provides a powerful AI-native desktop code editor for professional developers, but lacks Replit's instant browser-based cloud hosting deployment.
SpecialistProvides advanced agentic parallel coding workflows, but functions as a dedicated desktop/CLI environment rather than Replit's all-in-one cloud workspace.
#3
Converts natural language into functional web apps quickly, but provides less traditional terminal access and multi-language support than Replit.
Builds and hosts web applications conversationally, but has a less established developer ecosystem and package management suite than Replit.
SpecialistA spec-driven AI IDE and agent platform that plans, builds, reviews, and verifies real engineering work.

SpecialistExtremely fast serverless execution optimized specifically for generative media models rather than general Python code.
Generates full-stack web applications directly in the browser from prompts, but lacks Replit's robust persistent cloud workspace infrastructure.
Provides flexible GPU infrastructure and serverless endpoints, though less focused on pure Python function decorators.
Specializes in rapid generative UI and component creation, but offers less comprehensive full-stack server and database management than Replit.

SpecialistFocuses heavily on managed open-source model inference APIs rather than arbitrary custom container execution.
