# Caramel > Caramel is a free, open-source, privacy-first browser extension that finds and > applies coupon codes automatically at checkout. It does not sell browsing data > and does not overwrite creators' affiliate commissions. ## What it is - A browser extension for Chrome, Firefox, Edge, and Safari. - Free to use, with no paid tier and no account required to install. - Open source under the DevinoSolutions organization: https://github.com/DevinoSolutions/caramel - Positioned as an alternative to Honey for shoppers who care about privacy and about not hijacking creator commissions. ## How it works 1. You shop normally; Caramel detects a supported store's checkout page. 2. It looks up known coupon codes for that store from its own catalog. 3. It tries the codes at checkout and keeps the one with the best discount. ## Key pages - [Home](https://grabcaramel.com/): what Caramel is and how it works. - [Pricing](https://grabcaramel.com/pricing): the plan structure — Caramel is free. - [Get the extension](https://grabcaramel.com/apps): official store badges for Chrome, Firefox, Edge and Safari, what the installed extension does on each, and other Devino apps. - [FAQ](https://grabcaramel.com/faq): the questions shoppers actually ask, answered. - [Coupon extensions compared](https://grabcaramel.com/compare/coupon-extensions): Honey, Capital One Shopping, SimplyCodes, Rakuten, Coupert and Caramel side by side (price, how each makes money, rewards, accounts, browsers), every claim sourced. - [The Honey extension, explained](https://grabcaramel.com/honey-extension): what PayPal Honey does, how it makes money, the affiliate-link controversy and lawsuit, and how Caramel differs, every claim sourced. - [Agent setup](https://grabcaramel.com/agent-setup): onboard an AI coding agent; the machine-readable instructions are at https://grabcaramel.com/agent-setup/prompt.md. - [Coupon API](https://grabcaramel.com/api/coupons): public, read-only JSON; query with ?site= or ?search=; https://grabcaramel.com/api/coupons/stores?q= resolves store domains. - [Coupons](https://grabcaramel.com/coupons): browse the full coupon catalog. - [Store coupon pages](https://grabcaramel.com/coupons/amazon.com): per-store codes, one page per store domain, e.g. /coupons/amazon.com or /coupons/nike.com. - [Store directory A–Z](https://grabcaramel.com/coupons/stores): every store with live codes, by first letter. - [Supported stores](https://grabcaramel.com/supported-stores): which stores Caramel holds coupon codes for. - [Sources](https://grabcaramel.com/sources): where Caramel's coupon codes come from, and where to request a new source. - [Privacy policy](https://grabcaramel.com/privacy): what data Caramel does and does not collect. ## Install - Chrome Web Store: https://chromewebstore.google.com/detail/caramel-trusted-honey-alt/gaimofgglbackoimfjopicmbmnlccfoe - Firefox Add-ons: https://addons.mozilla.org/en-US/firefox/addon/grabcaramel/ - Microsoft Edge Add-ons: https://microsoftedge.microsoft.com/addons/detail/caramel/leodahchedhnenmiengkfpmmcdendnof - Safari (App Store): https://apps.apple.com/ke/app/caramel/id6741873881 ## Optional - [Full version](https://grabcaramel.com/llms-full.txt): the same facts plus the FAQ questions and answers and a privacy summary, in one document.
