Looking for a Klaro alternative, or weighing whether to self-host it? The real question isn’t “which open-source banner to pick” — it’s whether you want to spend developer time self-hosting just a cookie banner (and buy your legal documents elsewhere), or get the documents and a free banner, ready to use.
Here’s the straight comparison.
What Klaro does — and what it doesn’t
Klaro is a cookie consent banner. That’s the whole job:
- It shows a consent banner and blocks scripts until the visitor agrees.
- Either you self-host it (open-source build): install the script, configure it in a JavaScript file, wire each tracker to a category, and maintain it yourself.
- Or you take the paid hosted tier, Klaro Cloud — roughly €19 to €239/month — a recurring subscription, still for the banner alone.
The part that changes everything: Klaro produces no legal documents. No Privacy Policy, no Cookie Policy, no Terms of Use, no Terms of Sale. Yet regulators expect those in addition to the banner. A perfectly tuned banner on a site with no Privacy Policy is still non-compliant — and a missing document exposes you as much as a missing banner.
What WebLegal adds (and Klaro doesn’t have)
WebLegal handles compliance end to end, with two free tools around the documents:
- Free scanner — paste your URL: full list of cookies, 300+ tracker families and 36+ CMPs detected, with a compliance score. No signup. See the WebLegal compliance scanner.
- Free cookie banner — CDN-hosted, embeds in 2 lines, blocks trackers by default, Consent Mode v2 compatible, 14 languages. Free, no subscription, nothing to host. See the free GDPR cookie banner.
- The 4 legal documents — Privacy Policy, Cookie Policy, Terms of Use and Terms of Sale, tailored to your real stack and the applicable law, as a one-time purchase (no subscription).
Comparison
| What your site needs | Klaro | WebLegal |
|---|---|---|
| Privacy Policy | ❌ | ✅ |
| Cookie Policy | ❌ | ✅ |
| Terms of Use / Terms of Sale | ❌ | ✅ |
| Compliance scanner | ❌ | ✅ included, free |
| Consent banner | ✅ (self-host or €19-239/mo) | ✅ included, free |
| No-code install | ❌ (JS config, hosting) | ✅ 2 lines |
| Blocks trackers before consent | ✅ | ✅ by default (see the 37 trackers to block) |
| Pricing model | self-host, or €19-239/mo recurring | free banner + scanner, one-time documents |
Both do the banner. But on everything else — the documents, the scanner, no-code install, price — WebLegal covers what a site actually needs.
The real cost: free + one-time vs recurring + incomplete
This is where the gap opens up:
- Klaro — either developer time to self-host and maintain, or €19-239/month recurring for the hosted tier. And either way it’s only the banner: your documents are still to be produced elsewhere (a lawyer charges hundreds to thousands, or it’s another subscription).
- WebLegal — scanner and banner free, documents as a one-time purchase (Essential €19.90, Pro €34.90, Business €49.90). Pay once, keep them.
Put plainly: with Klaro you pay (in time or subscription) for one piece of the puzzle. With WebLegal the banner costs nothing and the whole puzzle is a single purchase. For a similar one-time-vs-subscription breakdown, see WebLegal vs CookieYes.
When Klaro might fit
One narrow case: a technical team (developer or agency) that wants to self-host its own banner, has the time to configure and maintain it, and whose legal documents are already written and kept up to date elsewhere. Outside that profile, the essentials are missing.
Why WebLegal for most sites
- You need the documents — Privacy Policy, Cookie Policy, Terms of Use, Terms of Sale — not just a banner.
- You’re not a developer and want a banner that embeds in 2 lines, nothing to host.
- You want to know where you stand first, with a free scanner that shows full results.
- You prefer a free banner + one-time documents over self-hosting effort or a monthly subscription.
Our verdict
Klaro solves one thing: the cookie banner — at the cost of technical self-hosting or a €19-239/month subscription, and it leaves you to produce your documents elsewhere. For the vast majority of sites, that’s neither the simplest nor the cheapest route.
WebLegal covers compliance in full: scan your site, generate the four documents, and switch on a free banner — no code, one-time purchase. The fastest way to decide: run the free WebLegal scan and you’ll see in 30 seconds what’s actually missing. If you’re comparing document generators specifically, Iubenda vs Termly vs WebLegal goes deeper on that.
