Sider Code
Describe how a site should work in plain English, and Sider Code rewrites the page live
Overview
Sider Code turns the read-only web into something you can reshape yourself. Instead of writing CSS selectors or extension code, you tell Sider Code what to change on a page, hide a comment section, restyle a cluttered layout, turn a scattered thread into a clean article, and it reads the page structure, writes the underlying code, and applies it in real time. The edit is remembered for your next visit and can be turned off or exported whenever you want.
It ships inside the existing Sider extension, which already has 10M+ weekly active users across Chrome, Edge, desktop and mobile, so Code isn't a standalone startup with everything to prove, it's a new capability added to a browser tool that already has real scale. That said, Code itself is brand new (it launched on Product Hunt on September 1, 2026), and letting an AI agent rewrite pages you visit and remember the change is a meaningfully different trust ask than a chat sidebar that just answers questions.
Key Features
Plain-English Page Editing: Describe a change and Sider Code updates the live page and remembers it for future visits.
Multi-Model Backing: Runs on GPT, Claude, Gemini and DeepSeek within the same Sider sidebar.
Toggleable, Shareable Changes: Saved edits can be switched on or off per site, or exported to share with someone else.
Bundled With Chat And Claw: Ships inside the same extension as Sider's AI chat and browser-automation (Claw) features, not a separate download.
Cross-Platform: Available on Chrome, Edge, macOS, Windows, iOS and Android.
Content And Ad Control: Can strip ads, remove clutter, or hide entire content formats you don't want to see.
Pricing
Starting price
$25/mo
Lite: $25/month. Includes a cloud computer (2 vCPU / 2 GB RAM / 40 GB SSD) plus Chat, Claw (browser automation) and Code (this feature).
Pro: $50/month. Upgraded cloud computer (2 vCPU / 4 GB RAM / 40 GB SSD), same feature set with higher usage quotas.
Max: $100/month. Top-tier cloud computer (4 vCPU / 8 GB RAM / 40 GB SSD).
Yearly billing is available per Sider's own FAQ, but the exact annual rate isn't shown on the pricing page itself.
Disclaimer: sider.ai blocks direct automated fetches, so this was confirmed through a mirrored copy of the live pricing page rather than a first-party screenshot. Third-party trackers still describe an older, cheaper $10 to $30 monthly structure that appears stale. Confirm current pricing on Sider's own site before buying.
Pros
Backed By A Large Existing User Base: Ships inside the Sider extension, which already has 10M+ weekly active users, not a from-scratch new product.
No-Code Page Customization: Reshape, restyle, or strip down any website with a plain-English instruction, no CSS or extension coding required.
Persistent And Reversible: Saved changes apply automatically on your next visit and can be toggled off or exported to share.
Multi-Model, Multi-Platform: Works across GPT, Claude, Gemini and DeepSeek, and the extension runs on Chrome, Edge, macOS, Windows, iOS and Android.
Confirmed Affiliate Program: 49% of order value on monthly plans (10.5% on yearly), with a 60-day cookie, the only one of this batch's four tools with a real program.
Cons
The Feature Itself Is Brand New: Sider Code launched on Product Hunt on September 1, 2026, so there is no independent track record yet for how well it holds up on complex or fast-changing sites.
Pricing Is Confusing To Verify: Sider's own current pricing page lists Lite/Pro/Max plans at $25/$50/$100 per month bundled with cloud-compute access, a notable jump from the $10 to $30 tiers many third-party reviews still quote, worth double-checking what you'd actually be billed.
A Real Trust Ask: You're letting an AI agent rewrite and remember changes to the live code of pages you visit, a bigger permission grant than a chat sidebar that only answers questions.
Launch Promo Is Temporary: Sider Code was reportedly offered free for a short window around launch; ongoing use requires one of the paid Sider plans above.
Official Site Blocks Automated Verification: sider.ai returns 403 to direct/bot traffic, which also makes it harder for outside reviewers, including us, to independently confirm claims beyond what Sider itself publishes.
What Makes It Unique
Where most AI browser sidebars, including Sider's own Chat, read a page and talk about it, Sider Code actually rewrites the page's live behavior from a plain-English instruction and remembers that change for next time, functioning less like a chatbot and more like a personal patch layer for any site you visit.
