The TypeScript framework for building, deploying, and observing AI agents
Define agents with instructions, models, tools, and runtime behavior, then compose typed workflow steps with retries and branching in TypeScript.
Give agents long-lived context with observational memory, semantic recall, and thread-aware storage.
Traces, metrics, logs, and datasets show every model call, tool call, and handoff in a searchable timeline.
Score agent runs against repeatable checks and experiments before changes reach production.

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 robust workflow automation platform uniting visual node-based building with AI agent orchestration and extensive app connectors.
SpecialistA spec-driven AI IDE and agent platform that plans, builds, reviews, and verifies real engineering work.
Generates full-stack web applications directly in the browser from prompts, but lacks Replit's robust persistent cloud workspace infrastructure.

SpecialistA developer platform providing pre-built integrations, authentication, and execution tools specifically for AI agents across third-party apps.
Specializes in rapid generative UI and component creation, but offers less comprehensive full-stack server and database management than Replit.

Instantly builds and hosts full-stack apps with integrated databases, but offers less granular terminal-level control than Replit.

Free / Open-sourceA comprehensive visual platform for building agent workflows and RAG pipelines via a no-code canvas instead of TypeScript.
