## NxCode

NxCode positions itself as an AI development team that replaces the cost and delay of hiring engineers. Instead of building a prototype in a browser sandbox, it runs code inside isolated Docker containers and verifies each task against acceptance criteria, then automatically detects and fixes errors through several iterations before a project is marked finished. Completed apps can be deployed to the global Cloudflare edge network with a single click.

The platform is built around a dual-agent system called Conductor plus Virtuoso: one agent plans and orchestrates the work, while the other executes code and validates results. Pricing is credit-based, starting at $5 per month, and creators can also publish apps to an internal marketplace and keep a 70% share of the revenue those apps generate. A free account lets you plan an app and review a build plan at no cost, while building and publishing require a paid subscription.

**Pricing & Plans:** Credit-based freemium. A free account lets you plan an app and review a build plan. Paid plans start at Lite $5/month (200 monthly credits, 1 dev container, 3 deployments) and Pro $20/month (1,500 credits, 3 containers, 10 deployments, no watermark, project export). Enterprise pricing is custom with unlimited credits, dedicated support, SLA guarantees, and on-premise options. New users receive a first-recharge credit bonus.

- **Dual-agent build engine:** A Conductor agent plans and orchestrates tasks while a Virtuoso agent executes code, aiming to produce production-ready output rather than throwaway prototypes.
- **Real Docker execution:** Code runs in isolated development containers instead of a browser sandbox, so applications behave like real software throughout the build.
- **Automatic error detection and repair:** Every task is checked against acceptance criteria, and errors are found and fixed automatically for up to three iterations.
- **One-click global deployment:** Ship finished apps to Cloudflare's edge network from the dashboard, with deployment counts tied to your plan.
- **Creator marketplace with revenue share:** Publish apps to the NxCode marketplace and keep 70% of the revenue when other users pay for them.

**Strengths:** Plain-English input means no coding or development experience is required; Free planning and build-plan review lets you evaluate ideas before paying; Deployment, debugging, and infrastructure are handled inside the platform; Credit-based pricing starts low at $5 per month and scales with usage

**Limitations:** Building and publishing require a paid subscription, so the free tier is limited to planning; Credit overages on the entry plan can add up for large or complex projects; The platform is comparatively new, so long-term reliability and ecosystem depth are still evolving

## 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
