Extension guide
Compare Google Apps Script Chrome extensions for autocomplete, type checking, themes, GitHub sync, and AI assistance inside script.google.com.
Updated September 2, 2026
Different jobs
The verified extensions below focus on areas such as themes, file organization, GitHub sync, and AI interactions. Many of them can run alongside an editor-intelligence tool instead of competing with it.
Native editor intelligence
It provides completions, diagnostics, navigation, and deterministic quick fixes in the Apps Script editor, plus optional AI quick fixes: 5 a month for signed-in accounts, with no monthly limit on myFunction Pro.
Compare by capability
| Category | What it covers |
|---|---|
| Editor intelligence | Type-aware completions, hover documentation, signature help, diagnostics, go to definition, and quick fixes inside the native editor. |
| Theming | Color themes, Zen modes, font controls, and visual editor customizations. |
| GitHub sync | Push, pull, diffs, and repository workflows that connect an Apps Script project to source-control services. |
| AI assistance | Chat, inline suggestions, or code-editing agents with scopes and provider arrangements that vary by extension. |
For a local project and command-line deployment workflow, compare the native editor with VS Code and clasp.
Verified listings
Purpose and scope are summarized from each Chrome Web Store listing as of September 2, 2026. Check the listing for the current version and status.
Theming, workflow tools, and experimental AI
Custom themes, multi-file search, folders, snippets, GitHub sync, a live error lens, and experimental AI autocomplete and chat.
It runs inside the Apps Script editor. Its AI uses a provider or local model selected by the user; cloud provider charges may apply.
View Chrome Web Store listingGitHub and source-control sync
Pushes and pulls Apps Script code with GitHub, GitHub Enterprise, Bitbucket, or GitLab, with diffs and file selection.
Its listing says Pull fetches code and overwrites the project rather than performing a Git merge. It requires Google OAuth to use the Apps Script API.
View Chrome Web Store listingEditor workflow and AI assistance
An in-editor extension with an AI assistant, ghost-text suggestions, GitHub integration, themes, file tree, Vim support, search and replace, and collaboration features.
The listing describes an extension operating in the Apps Script editor, not a standalone Apps Script runtime or hosting product.
View Chrome Web Store listingAI assistance
AI chat, inline completions, and an agent that edits code in the Apps Script editor, with project context, plans, diffs, and revert controls.
Its listing says the user supplies an AI-provider API key and sends code to that selected provider for requested assistance.
View Chrome Web Store listingTheming and editor productivity
Dark themes, Zen mode, snippets, font controls, rainbow brackets, TODO highlighting, code statistics, and settings import and export.
Its stated feature list is scoped to editor appearance and productivity tools; it works offline and does not require an account.
View Chrome Web Store listingComplementary tools
A theme or editor-productivity extension can sit alongside myFunction when you want a different visual workspace. GitHub-sync extensions serve a separate source-control need; use one when the project needs that connection.
myFunction is for people who want type checking, project-wide diagnostics, and quick fixes without leaving script.google.com. It does not replace a local Git workflow.
