Juggler vs Sider Code: Features, Pricing & Which Is Better (2026)

A side-by-side comparison of Juggler and Sider Code — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.

Juggler

Julian Storer

Free

A native desktop workbench for AI coding agents with branching conversation trees, inspectable tool calls and editable context.

Branching Conversation Trees: Fork the session at any point, recursively, so competing approaches and tangents run side by side without polluting the main context.
Miller Column Navigation: A Finder-style column layout lays out tool calls, item properties and nested sub-threads for long reading and editing sessions.
Transaction Inspector: Open any model transaction to see the assembled system prompt, messages, tool definitions, output, token use, timing and stop reason.
The Context Surgeon: Fold history into a new thread, move or copy items between branches, expand a branch back into its parent, and undo structural changes.
Local or Remote Sessions: Run the desktop app locally or the headless binary on the machine holding the code, then attach from the app, a browser or a phone.
Durable Sessions: Sessions are stored on disk as live-synced Yjs documents, so quits, relaunches and dropped connections do not lose the conversation.
Automatic Context Sizing: Juggler measures the full request before each call, reserves room for the answer and compacts older history before limits become an error.
Inspectable MCP Tools: Follow an MCP handoff end to end - schema offered, arguments generated, approval, result and errors - with server status, logs and per-tool filtering.
JavaScript Extension SDK: Context items, LLM loop strategies, slash commands, viewers and Pinboard tabs are extensions you can fork or replace, under a permissive Apache-2.0 SDK.

Exploring Competing Fixes: Branch a thread into two sub-threads to try different approaches to the same bug and compare results before committing.
Auditing Agent Behavior: Inspect exactly what the model received and returned when an agent makes a surprising edit to the codebase.
Remote Development: Run the server on a dev box or GPU machine where the repository lives and drive the same live session from a laptop or browser.
Long Refactors: Keep a multi-hour session alive across quits and reconnects, with the agent paused awaiting approval for its next step.
Provider Comparison: Drive Claude Code, Codex, Copilot, Gemini and local Ollama models through one interface to compare behavior on the same task.
Custom Tooling: Write JavaScript extensions that add slash commands, file viewers or new LLM loop strategies to the workbench.

Sider AI

Freemium

Browser feature that rewrites any webpage from a plain-language instruction and remembers the customization for future visits.

Plain-Language Page Editing: Describe the change you want in your own words and Sider Code applies it to the live page without scripts or DOM inspection.
Persistent Per-Site Customizations: Saved changes reapply automatically the next time you visit that site instead of vanishing on reload.
Structural Rewrites, Not Just Blocking: Beyond hiding elements, it can restructure content, add new actions, and transform how a page works.
Page-Content Understanding: Combines comprehension with modification so it can summarize, extract, and explain page content in the same operation.
Comment Thread Condensation: Turns hundreds of Reddit or Hacker News comments into an overview or a structured debate view.
Reading Mode Generation: Converts scattered social threads and long chapters into clean articles with tables of contents and comfortable layouts.
Distraction Removal: Strips elements like the YouTube Shorts shelf or applies dark mode to bright document editors.
Bundled With Sider Suite: Ships alongside Sider Chat's frontier-model access, Claw browser automation, and Create image, video, and slide generation.

Research Reading: Condensing long comment threads into the key viewpoints before deciding whether the discussion is worth reading in full.
Long-Session Comfort: Applying dark mode or a calmer reading layout to writing tools used for hours at a time.
Focus Enforcement: Permanently removing recommendation shelves and distraction surfaces from sites you use daily.
Workflow Adaptation: Reorganizing an internal or third-party web tool so its layout matches how you actually work rather than the default.
Content Extraction: Pulling structured information out of a page and reshaping it into a more usable view.
Accessibility Adjustments: Reshaping cluttered pages into cleaner, easier-to-navigate layouts without waiting on the site owner.
