VS Code-compatible open-source editor
Metadata checked Aug 18, 2026
Rank 1 for functional fit and maturity: it offers the broadest CodeRunner-like editor, task, and debugging workflow with the strongest ecosystem and current macOS distribution.
The closest free replacement for CodeRunner: a mature VS Code-compatible editor with extensions, tasks, terminal, and debugging, distributed as telemetry-disabled MIT-licensed binaries for Intel and Apple Silicon Macs.
- 01VS Code-compatible editor with extensions, tasks, terminal, and debugging
- 02MIT-licensed, telemetry-disabled community binaries
- 03macOS 12+ Intel and Apple Silicon packages
- 04Open VSX extension registry for open extension distribution
- Some Microsoft Marketplace-only extensions are unavailable because VSCodium uses Open VSX.
- Language runtimes, compilers, and interpreters must be installed separately.

Zed
Fast native editor with tasks and debugging
Metadata checked Aug 18, 2026
Rank 2 for product quality and maintenance: a polished, actively released Mac-capable editor with first-party tasks and debugging, tempered by less automatic one-file execution and paid hosted AI extras.
Full review — capabilities, 3 caveats, evidence
A fast Rust-based editor with integrated terminal tasks, a DAP debugger, Git tooling, and a $0 personal tier. It is more polished than CodeEdit but less turnkey than CodeRunner for ad-hoc execution across many languages.
- 01Integrated terminal tasks that can run and rerun project commands
- 02Native DAP debugger for multiple programming languages
- 03First-class Git workflows and collaboration features
- 04GPL-3.0-or-later source with a free Personal editor plan
- The free Personal plan is the editor without Zed-hosted AI; hosted models and higher quotas are paid.
- The current macOS download page presents an Apple Silicon build; verify compatibility for Intel Macs.
- Code execution is task- and terminal-driven, so project setup is less automatic than in CodeRunner.

CodeEdit
Native macOS editor, free forever
Metadata checked Aug 18, 2026
Rank 3 for native Mac fit: its task and debugging feature set maps well to CodeRunner, but its explicitly pre-production status lowers confidence versus VSCodium and Zed.
Full review — capabilities, 3 caveats, evidence
A Swift-native macOS editor with syntax tooling, terminal, task running, debugging, language servers, and Git integration. It is the closest Mac-native analogue, but remains a pre-production project.
- 01Swift-native macOS architecture
- 02Syntax highlighting, completion, search/replace, snippets, terminal, task running, debugging, and Git
- 03Recent release improvements to task output and task controls
- 04MIT-licensed and free forever
- The project explicitly says it is in development and not recommended for production use.
- Language-server installation and task/debugging capabilities are still evolving.
- Local language runtimes are separate and are not bundled with the editor.
