About Sider Code
Sider Code is a Chrome extension that lets users modify how existing websites behave using plain language instructions. Instead of writing code manually, users describe a change they want, and the tool interprets the page, generates front-end scripts, and applies the modification. Created by the team behind Sider, it launched with a three-day free access period for all users.
Review
Sider Code approaches website customization from a different angle than most tools. Rather than offering pre-built templates or requiring users to learn scripting, it accepts natural language descriptions of desired changes. The generated code can be saved, toggled on or off, and exported or shared with others.
Key Features
- Natural language input: describe a website change in plain words, and Sider Code generates the corresponding front-end script using the ChatGPT-5.6 model
- Persistent modifications: saved features remain active on subsequent visits and can be switched off or on at any time
- Export and sharing: generated features can be exported, and a share function exists with plans to simplify the sharing process
- Content filtering: users can remove ads, clutter UI components, or entire content formats they don't want to see
- Page reshaping: the tool can restructure existing content, such as turning comment threads into focused articles with navigation or converting discussions into visual maps
Pricing and Value
Pricing for Sider Code beyond the initial three-day free period is not yet defined in the available information. The launch announcement states that the tool was free for everyone for the first three days after release. No subscription tiers, per-feature costs, or usage limits have been published at this time.
Pros
- Removes the need to write or understand code when modifying website behavior
- Changes persist across sessions and remain under user control with on/off toggles
- Can function as a customizable ad blocker and UI clutter remover
- Generated features can be exported and shared with other users
- Works on top of existing websites, so users don't need to switch to alternative platforms
Cons
- Generated code is currently frozen after creation, meaning it doesn't adapt when the underlying website updates its structure
- May struggle with heavy single-page applications where the DOM changes dynamically during scrolling
- Not well suited for users who need modifications that automatically adjust to frequent site redesigns or complex interactive web apps
Sider Code fits users who want to reshape specific websites they visit regularly without learning scripting, such as removing unwanted content formats or reorganizing how information appears. It's also relevant for those who want shareable customizations for sites like Reddit or social media feeds. Teams that need reliable automation on rapidly changing web applications may find the current frozen-code limitation restrictive until the planned detection feature ships.
