The best coupon extensions, compared

Every coupon extension compared here is free to install. What differs is how each makes money, what it asks of you, and whether you can check what it does. Honey, Capital One Shopping, Rakuten and Coupert each say stores may pay them commissions when you shop with them, and share part of that back as rewards; SimplyCodes says it may earn a commission when you buy through its links. Caramel contains no affiliate code, has no rewards program, and publishes its source code; we found no published source code for the others.

Checked on . Every statement about another extension comes from its maker's own site, its browser store listing, a court filing or a named news outlet, numbered in the sources below. Caramel is our extension, so check those sources rather than taking our word for it.

Which one should you use?

You want rewards or cash back
Rakuten and Coupert pay Cash Back, and Capital One Shopping and Honey give rewards you redeem later (Capital One Shopping Rewards, PayPal Rewards points). SimplyCodes ended its token rewards in August 2026, and Caramel has no rewards program.
You don't want an account
Caramel needs none. Honey's help guide starts with signing up, Capital One Shopping's promo-code steps include creating an account, and Coupert's Firefox and Safari how-tos have you sign up or log in.
You want to check what the extension does
Caramel publishes its source code (AGPL-3.0), so what it does can be read rather than taken on trust. We found no published source code for the others.
You buy through creators' links
Caramel contains no affiliate code, so it never adds or replaces a referral link or cookie. Honey, Capital One Shopping, Rakuten and the free Coupert extension say stores may pay them commissions when you shop with them, and SimplyCodes says it may earn a commission when you buy through its links; Coupert's paid Coupert Pure says it has no merchant ties or cookie overrides. The timeline below covers the lawsuit over Honey and creators' links.

Want the one with no affiliate code? Caramel finds and applies coupon codes at checkout. Free, no account, open source.

What happened with Honey

  1. YouTuber MegaLag publishes "Exposing the Honey Influencer Scam", alleging that Honey replaced creators' affiliate links with its own and showed shoppers limited coupon options at partner stores. PayPal responded that "Honey follows industry rules and practices, including last-click attribution," and told USA TODAY that merchants ultimately decide which coupons are offered through Honey.[19][20]

  2. Google announces a Chrome Web Store policy: an extension may add an affiliate link, code or cookie only when it gives the user a direct, transparent benefit, and only after a related user action. Google said enforcement would begin on June 10, 2025.[21][22]

  3. By this date Honey's Chrome Web Store listing carries the disclosure "When you use PayPal Honey, merchants may pay us affiliate commissions." It is still there in September 2026.[23][4]

  4. In a proposed class action brought by creators against PayPal over Honey (Wendover Productions v. PayPal, N.D. Cal., case 5:24-cv-09470), the court dismisses the first amended complaint with leave to amend, because it did not plausibly show an injury traceable to PayPal.[24]

  5. The same court denies PayPal's motion to dismiss the second amended complaint, so the creators' claims go forward. This is a ruling on the pleadings, not a finding that PayPal did anything wrong.[25]

  6. Honey is still a live PayPal product: its Chrome Web Store listing shows 13,000,000 users and an update on September 8, 2026.[4]

Questions people ask

What is the best coupon extension?

It depends on what you want in return. For cash back, Rakuten and Coupert pay Cash Back, and Capital One Shopping and Honey give rewards you redeem later. For an extension that needs no account and whose behavior you can check yourself, Caramel publishes its source code and contains no affiliate code.

SimplyCodes vs Honey: which is better?

Both are free and both surface coupon codes at checkout: Honey says it looks for and applies them automatically, while SimplyCodes shows verified codes and leaves you in control. Both say they may earn commissions. Honey pays PayPal Rewards points; SimplyCodes removed its token rewards in August 2026, saying they never made the codes better. Honey is also far larger, with 13,000,000 Chrome Web Store users against SimplyCodes' 90,000 (September 26, 2026). We found no published source code for either.

Do coupon extensions make money from affiliate links?

Most do. Honey, Capital One Shopping, Rakuten and the free Coupert extension each say on their own site or store listing that stores may pay them commissions when you shop with them, and SimplyCodes says it may earn a commission when you buy through its links. The exceptions here are Caramel, whose extension contains no affiliate code, and Coupert's paid Coupert Pure, which says it has no merchant ties.

Is there an alternative to Capital One Shopping that needs no account?

Yes. Caramel finds and applies coupon codes with no account at all. Capital One Shopping's own promo-code steps include creating an account (you don't need to be a Capital One bank customer), and it pays its rewards as Capital One Shopping Rewards.

Is Honey still available in 2026?

Yes. PayPal Honey is still on the Chrome Web Store, where its listing showed 13,000,000 users and a September 8, 2026 update when checked on September 26, 2026. It is also listed for Edge and Safari; its Firefox add-on was last updated in February 2021.

Is there an open-source coupon extension?

Yes. Caramel's extension and website are open source under the AGPL-3.0 license and published on GitHub, so anyone can check what the extension sends and that it contains no affiliate code. We found no published source code for the other extensions compared here.

More about Caramel itself is in the Caramel FAQ, and the stores it has codes for are in the store directory.
