About ABAP Dojo
ABAP Dojo is a free, browser-based ABAP playground that lets you write, lint, execute, and validate ABAP code — no SAP system required. Everything runs entirely in your browser using the abaplint ecosystem.
Whether you're an ABAP consultant wanting to test a snippet, a developer validating LLM-generated code, or someone learning ABAP without access to a SAP system, ABAP Dojo gives you a fast, private, zero-setup environment to get things done.
Features
Execute ABAP
Transpile and run ABAP code in the browser. WRITE output displayed instantly.
AI Pitfall Detection
Catch patterns LLMs commonly get wrong — STRING vs CHAR, Python-style loops, and more.
163 Lint Rules
Real-time ABAP linting powered by abaplint. Issues highlighted as you type.
Safe for Client Code
100% client-side. Your code never leaves your browser — no server, no logging.
How It Works
- You write ABAP code in the Monaco Editor — the same editor that powers VS Code.
- abaplint parses your code in a Web Worker and reports lint issues in real time.
- When you click Run, the abaplint transpiler converts your ABAP to JavaScript.
- The transpiled code executes in a sandboxed iframe and WRITE output is returned to the UI.
Who Is This For?
- ABAP consultants — test snippets and validate logic outside of client systems.
- LLM users — verify that AI-generated ABAP code actually works before using it.
- ABAP learners — practice syntax and explore examples without an SAP license.
- S/4HANA migration teams — check legacy-to-modern syntax conversions quickly.
Technology
ABAP Dojo is built on top of abaplint by Lars Hvam — an open-source ABAP toolchain released under the MIT License. The abaplint ecosystem provides everything needed to parse, lint, transpile, and run ABAP entirely in the browser.
- @abaplint/core — ABAP parser and 163-rule linter
- @abaplint/transpiler — ABAP to JavaScript transpiler
- @abaplint/runtime — runtime support for transpiled ABAP
The editor is Monaco Editor. The UI is built with React, TypeScript, and Tailwind CSS, bundled with Vite.
