## Replit

Replit began as one of the most popular browser-based coding environments and has evolved into an AI-first app and website builder. You describe what you want to build, and Replit's agent plans the work, writes production-ready code across the stack, iterates on feedback, and can publish the running app for you. Because everything happens in the cloud, there is no toolchain to install and no local environment to maintain.

The platform pairs the agent with the infrastructure a real product needs: authentication, a managed database, hosting, monitoring and more than a hundred integrations such as OpenAI, Stripe and Google Workspace. Recent releases added intelligent model routing that cuts the average cost of complex builds, an infinite canvas for visual design iteration and multi-user collaboration features aimed at teams.

Replit suits a very wide audience. Founders use it to go from idea to landing page or prototype in an afternoon, product managers build interactive demos instead of static specs, designers move straight from concept to functioning UI, and engineering teams use it to spin up internal tools quickly. A generous free mode lets people create without token costs, while paid plans unlock more powerful models, more storage and commercial usage.

**Pricing & Plans:** There is a free mode with limited chat hours and projects. Replit Core is about $20/month (about $18/month billed annually), and Replit Pro is roughly $90–100/month billed annually for commercial work. Enterprise plans add SSO/SAML, SOC 2 controls and admin features.

- **Agentic app generation:** Describe the product you want and the agent plans, codes, tests and iterates on a working full-stack application.
- **Built-in full-stack infrastructure:** Authentication, databases, hosting and monitoring work out of the box, so apps scale without separate DevOps work.
- **Free mode for experimenting:** A no-cost mode lets you brainstorm and build without spending tokens before upgrading to stronger models.
- **100+ integrations:** Connect services such as OpenAI, Stripe and Google Workspace in minutes rather than writing glue code.
- **Team and enterprise controls:** Multi-user collaboration, SSO/SAML, SOC 2 alignment and admin controls support professional and regulated use.

**Strengths:** No local setup; everything runs and deploys in the browser; Agent handles full-stack code, infrastructure and publishing; Free mode makes experimentation accessible; Strong collaboration, integrations and enterprise security controls

**Limitations:** Complex or highly custom architectures may still need manual engineering; Agentic build costs can rise quickly on heavier projects; Less control over low-level infrastructure than managing your own stack

## Stately

Stately started as a visual editor for XState, the popular JavaScript state machine library, and has grown into a full modeling and reasoning layer for application logic. Instead of describing behavior in prose or letting it hide inside conditional branches, you draw it as a statechart: states, transitions, events, guards, and actions on one canvas. The editor renders the graph and the underlying configuration side by side, so changing the diagram updates the source and vice versa. Stately's positioning is that a code diff shows which lines moved, but not that a refund path became unreachable; a statechart shows the behavior change directly.

The platform's newer focus is agentic development. Stately runs a hosted MCP server over streamable HTTP that Claude Code, Codex, Cursor, VS Code, and other MCP clients can connect to in a few commands. Through it, an agent can scan a repository, extract machines from source, validate a machine, convert between XState, SCXML, Mermaid, and D2, diff two versions of a machine, enumerate paths, simulate events, and render diagrams. There is also a CLI (npx statelyai) for scanning, pushing, pulling, and diffing, and the diff command can be wired into CI as a gate that fails a build when machine semantics change.

Beyond individual machines, Stately models whole systems: architecture views connect services, actors, and machines from imported C4, Structurizr, D2, or Mermaid diagrams. The inspector attaches to a running app and streams live state, context, events, and actor activity so you can see what the software is actually doing. The product is used by product engineers, platform teams, and QA and testing groups who need shared, reviewable models of complex logic.

**Pricing & Plans:** Stately has a generous free tier: unlimited public projects and machines, browsing and simulating public machines, export to JavaScript and TypeScript, and 200 AI credits per month. Pro is $39/month monthly or $33/month billed annually and adds unlimited private projects, codebase sync via GitHub, CLI, and SDK, test path generation, lock and version history, live simulation, and 1,000 AI credits. Team is $199/month monthly or $167/month billed annually for up to 10 members, shared projects, admin roles, and 4,000 shared credits. Enterprise adds custom hosting, SSO, audit logs, embedding, custom integrations, and custom export formats with quoted pricing.

- **Visual statechart editor:** Model states, transitions, events, and parallel regions in a drag-and-drop canvas that renders as clean, readable statecharts humans can review at a glance.
- **Simulation and inspection:** Attach to a running app to watch active states, emitted events, and actors as they happen, with live simulation mode on paid plans.
- **MCP server for coding agents:** A hosted MCP server plus CLI lets Claude Code, Codex, Cursor, and VS Code scan repos, map behavior, diff machines, and apply structured edits.
- **Code generation and format conversion:** Move between XState, SCXML, Mermaid, and D2, or let the tool generate machine code directly into your JavaScript and TypeScript project.
- **Diff, versioning, and CI gates:** Use GitHub, CLI, or SDK sync plus a diff command that can fail CI builds when machine semantics change unexpectedly.
- **Architecture and system modeling:** Import C4, Structurizr, D2, or Mermaid diagrams to map how services, actors, and machines connect across a whole system.

**Strengths:** Turns abstract application logic into diagrams teammates and reviewers can actually read; First-class MCP support lets Claude Code, Codex, Cursor, and VS Code reason about your real state machines; Free tier is genuinely usable for public projects, simulation, and exports; Round-trips between the visual diagram and XState source instead of being a one-way drawing tool

**Limitations:** The underlying statechart/XState concepts have a real learning curve for newcomers; Most advanced collaboration features are tied to per-seat Team pricing, which adds up quickly; AI credits are metered, so heavy generation usage on the free tier runs out fast; Some capabilities (custom hosting, SSO, audit logs) are Enterprise-only
