📝 5.0.0-beta.51 · Standalone editor · Free download

A code editor that
shows you the diff.

gald3r_ideis a standalone desktop code editor sharing one editor core with Gald3r Throne's built-in IDE section. Every AI-proposed edit renders as a diff you accept hunk by hunk — nothing reaches disk unseen.

Positioning

Between Notepad++/UltraEdit and early VS Code

“I want to see the code changes, biggest complaint I have with Claude Code, Codex, New Cursor... I do not need all of the plugin/marketplace/extensions of VS Code... something that will appeal to the developers and programmers who don't want to not see the code.”
— the owner, on why gald3r_ide exists

In scope: syntax highlighting from per-language definition files, code folding, comment toggling, find/replace, multi-tab editing, a file tree, a settings page, and an AI agent panel that edits files through a visible, per-hunk-acceptable diff.

What's inside

Built for people who read code

AI edits as diffs, per hunk

The agent panel never writes a file directly. Every proposed change renders as a unified diff, each hunk gets its own Accept/Reject, and only accepted hunks are written — through the same save path and conflict detection a manual edit goes through. An append-only approvals ledger records what was proposed, accepted, and rejected.

25 languages, plain JSON

Syntax highlighting, code folding, and comment toggling are driven by one JSON file per language — including several CodeMirror ships no first-party pack for: Shell, PowerShell, SQL, TOML, Batch, Dockerfile, git config/ignore files, TOON, plus PL/SQL, PostgreSQL, SQLite, and DuckDB SQL dialects.

Three keybinding presets

VS Code (the default), Notepad++, and UltraEdit — switchable live from the right-click menu or the settings page, and remembered per user. No relearning muscle memory built up in whichever of the three you already know.

One editor core, no fork

gald3r_ide and Gald3r Throne's own IDE section both import the same @gald3r/editor-core package as a workspace dependency — the CodeMirror 6 surface, file tree, tabs, find/replace, diff viewer, and settings page are one implementation, not two.

One settings page

Fonts, theme (light/dark/system), the keybinding-preset picker, a Language Files registry with per-extension overrides, and the agent provider/model — shared by Throne's IDE and gald3r_ide.

Commands get the same review

The agent running a command goes through the same approval discipline as writing a file: a proposed command is queued for your explicit sign-off before it executes. The agent cannot invoke a command directly.

Honestly, not there yet

What gald3r_ide deliberately doesn't do

  • ·No extension or plugin marketplace, and no third-party extension API of any kind — by design.
  • ·No remote-dev (SSH/container) targets.
  • ·No multi-root workspace concept — opening another folder replaces the currently open one.
  • ·No reimplementation of Throne's world_tree auth, swarm observability, avatar/theatre-voice, addon installer, or workspace-graph surfaces — those stay Throne-only.
  • ·No new diff algorithm — the existing unified-diff engine is reused as-is.
Windows shell integration status is unconfirmed. The product documentation describes “Open with gald3r_agent” right-click Explorer integration as specced and in progress, not yet shipped, while the engine's own changelog lists the underlying --register-shell / --unregister-shell flags as landed. This page does not resolve that discrepancy — confirm against a live build before relying on it. Theme-token sharing with Throne is also still in progress, not fully landed yet.
