Build with the IDE you already love.

Createrun is a low-code platform that doesn't punish developers for wanting to write code. Editor IDE for fast wiring. VS / VS Code AppClient for serious logic. Compiler (Roslyn worker) for incremental builds. MCP server for agent-driven scaffolding. Pick your tool — they all speak the same model.

SIX TOOLS · ONE PLATFORM
Authoring

Editor IDE

Browser-based IDE for forms, queries, workflows, BPM. Syntax-aware, multi-tab, live compile feedback. The default authoring surface for analysts and full-stack developers.

  • Drag-and-drop Form Designer
  • Visual Query builder
  • Workflow + BPM editor
  • Live Compiler errors
VS / VS Code

AppClient

Visual Studio extension + VS Code extension. Generated partial classes, full IntelliSense, F5 debug, sync command from your local repo to a Createrun instance.

The Visual Studio and VS Code extensions are currently in private preview — access is provisioned with your developer sandbox.

  • VS 17.9+ extension
  • VS Code TypeScript extension
  • Sync To Createrun command
Build

Compiler

Roslyn-based, supervised, version-aware. A supervisor automatically restarts crashed build workers; host and workers talk over fast binary IPC. Cold-start mitigated by a warm worker pool.

  • Roslyn-based incremental builds
  • Isolated, supervised worker processes
  • Per-worker memory budget
  • Version-aware framework refs
AI

MCP Server

A broad, continuously expanding MCP surface for building, changing, testing, and operating Createrun applications. Stdio for local agents, HTTP for hosted. Wire Claude Code, Codex, Cursor, or any MCP-aware client. Test mode for reproducible runs.

API

Gate Methods

Createrun exposes a consistent, gate-based API surface instead of ad-hoc REST endpoints.IAsyncGate<T>contract.ServiceBuilder.Add(...)registers handlers. The Service entrypoint is gate-only by architecture.

  • IAsyncGate pipeline
  • A consistent response envelope
  • Request tracing across services
Code-gen

AppClient code-gen

Form / Query / Workflow definitions auto-generate strongly-typed C# partial classes via the AppClient MSBuild task. Compile your app as a regular csproj — generated partials sit alongside your hand-written code.

  • MSBuild .targets integration
  • Hot-reload on Save
  • Resilient MSBuild integration

THE CREATERUN AGENT — TOOL REFERENCE AT A GLANCE

The Createrun Agent works through a broad, continuously expanding MCP surface for building, changing, testing, and operating Createrun applications —updated with every release. The interface is an open standard (MCP), so it plugs into the AI tools you already run — Claude Code, Codex, Cursor, or any MCP-aware client. Supported operations are versioned in a public capability matrix, so you can see exactly what is live, partial, or planned. Capability areas:

  • Session & context— pick the organization, solution, and workspace every subsequent call operates on.
  • Forms & fields— create and evolve forms, pages, fields, and form actions (e.g.create_form,add_field).
  • Queries— build, inspect, and run visual queries against workspace data.
  • Workflows & BPM— design multi-stage processes and convert flat forms into approval-driven workflows.
  • Data— read, insert, update, and delete form rows with validators and concurrency checks applied.
  • Compile & publish— trigger builds, read diagnostics, and push approved changes out (e.g.compile).
  • Workspaces— branch, bind, push, and pull workspaces backed by real Git.
  • Marketplace— package and publish solutions through the Editor → Marketplace pipeline.
  • Administration— manage access, test mode, recycle bin, and audit-relevant state.

Mutations queue into reviewable batches — staged before they apply, with best-effort rollback — and every request carries a correlation id for end-to-end tracing. The full per-tool reference ships with the MCP server.

AGENTS.MD

Every Createrun MCP install ships withAGENTS.md— a practical guide for AI agents authoring on the platform. TL;DR + form rules + DynamicBox conventions + test-mode workflow + under-the-hood notes. Read once, save thousands of tokens of trial-and-error.

DATA & INTEGRATION

ForgetDB ORMruns on the enterprise databases your organization already standardizes on — PostgreSQL, MSSQL, MySQL, Oracle, and embedded engines among them. Expression-tree query API. Provider-pattern architecture with typed sources.

Createrun.IOstores documents where your organization requires — local, network, database, S3, Azure Blob, Google Drive, FTP and more, behind one API. Document Library uses this layer.

Current providers and compatibility status are maintained in the versioned integrations matrix — see/integrations.
