BBLabs vs OWASP Juice Shop: which one to practice web hacking?

Juice Shop is the modern deliberately vulnerable app, gamified and free; BBLabs is a platform of bug bounty labs based on real reports, with writeups and in Spanish. An honest comparison, updated July 2026.

TL;DR

OWASP Juice Shop is free, open source, modern and a lot of fun: a challenge app with a score board that covers the entire OWASP Top 10. Its downside: it's a generic app, in English, with fixed challenges and no official writeups. BBLabs is ideal for practicing real bug bounty on labs based on real reports, with step-by-step writeups, live labs in the browser and everything in Spanish, on a single plan from €7.99/mo. They're complementary: Juice Shop to gamify the fundamentals for free, BBLabs for the jump to real cases.

Note: OWASP Juice Shop is a free open-source project from the OWASP Foundation. We describe its strengths qualitatively (free, modern, gamified, offline) to avoid misleading you: it doesn't compete on price, it competes on philosophy.

What is OWASP Juice Shop and why is it so loved?

OWASP Juice Shop is probably the most popular deliberately vulnerable application in the world. It's modern (a JavaScript SPA), maintained by the OWASP Foundation, and its big hook is gamification: a score board with dozens of hidden challenges you discover and solve, covering the entire OWASP Top 10 and quite a bit more. All free and offline.

As a test bench for learning web hacking, it's outstanding and we recognize that without reservations. It's addictive, well built, and teaches you to think like an attacker in an app that resembles a real website far more than the classic vulnerable apps.

Where Juice Shop falls short

Juice Shop's limit is that, however good it is, it's a single app with a fixed challenge set. Once you clear them all, the content doesn't grow unless they release a new version. The writeups aren't official: you depend on community guides, almost always in English. And it's still an environment designed to be hacked, not a production application like the ones you find in a real bug bounty program.

BBLabs covers exactly that gap: each lab replicates a real bug bounty case, with its context, its exploitation chain and the bounty that was paid. There's new content every Monday, ordered by difficulty, and each lab comes with its official step-by-step writeup. It's not a challenge set you exhaust: it's a practice ground that grows every week.

Gamification: score board vs ranking and flags

Here both play well. Juice Shop's score board is addictive: watching challenges tick off is hugely motivating. BBLabs also gamifies, but in a bug-bounty-oriented way: you capture flags when you solve each lab, climb a roadmap that shows your next step, and compete in a public ranking of Spanish-speaking hunters. The difference is the goal: Juice Shop gamifies learning the OWASP Top 10; BBLabs gamifies your progress as a real bug hunter.

Language and support: self-taught English vs guided Spanish

Juice Shop supports several languages in its interface, but the learning ecosystem (guides, writeups, forums) is mostly in English and you learn on your own. BBLabs is 100% in Spanish and each lab comes with its writeup, plus a free Academy with 16 vulnerability categories (theory, payloads and methodology). You can study the theory without paying anything and then practice on real labs with support, in your language. For a Spanish speaker who's starting out, that guidance makes the difference.

Who each one is for

Choose BBLabs if...

  • You want to practice bug bounty with real cases
  • You want official step-by-step writeups
  • You prefer Spanish over English
  • You don't want to set up servers (live labs)
  • You want new content every week
  • A ranking and a Spanish-speaking community motivate you

Choose OWASP Juice Shop if...

  • You want to start free and with no commitment
  • Solving gamified challenges hooks you
  • You want to cover the OWASP Top 10 in one app
  • You prefer a 100% offline, local environment
  • You don't mind it being in English
  • You're after a modern, well-built app

Verdict: Juice Shop to gamify for free, BBLabs for the jump to real bugs

It's not a duel with a single winner. OWASP Juice Shop is a free, modern, gamified resource that does its job very well: hooking you and teaching you the OWASP Top 10 in a real app. It's an honest recommendation and it costs nothing. BBLabs does something else: it turns real bug bounty reports into curated labs you practice in Spanish, with writeups, live labs and a roadmap that guides you from Easy to Insane. If you've already cleared Juice Shop's challenges and want to train on real cases that have been paid, BBLabs is the natural next step — and you can start for free with the Academy.

Frequently asked questions

OWASP Juice Shop or BBLabs to practice web hacking?

It depends on what you're after. OWASP Juice Shop is free, open source and one of the best deliberately vulnerable apps out there: modern (JavaScript), gamified with its famous challenge score board and covering the entire OWASP Top 10. It's tremendous fun and costs nothing. BBLabs approaches practice differently: instead of a challenge app, each lab replicates a real bug bounty report (HackerOne, Bugcrowd, Intigriti) with its step-by-step writeup, in Spanish, and with new content every week. If you want to clear challenges for free in a modern app, Juice Shop. If you want to train to find bugs that actually get paid, with support and in your language, BBLabs.

Are Juice Shop and BBLabs complementary?

Very much. Juice Shop is a free, gamified test bench ideal for getting hooked: you clear challenges, climb the score board and learn the OWASP Top 10 in a real, well-made app. BBLabs is the next step up: labs based on real reports, with official writeups, live labs in the browser and a roadmap that takes you from Easy to Insane. Many hunters start hunting challenges in Juice Shop and jump to BBLabs when they want to practice on real cases, in Spanish and with material that explains exactly why each bug was paid.

Is BBLabs an alternative to OWASP Juice Shop?

For practicing web hacking, yes, though they're not the same. Juice Shop is a single (excellent) application with a challenge set covering the OWASP Top 10; its value is being free, modern and gamified. BBLabs is a platform with dozens of labs curated from real reports, with new content every Monday, writeups, a free Academy and everything in Spanish. If in Juice Shop you were after continuous variety and real cases with explanations, BBLabs is a very aligned alternative. If what you want is a free challenge app to gamify your learning, Juice Shop is still an absolute reference.

Which one is cheaper?

OWASP Juice Shop, clearly: it's free and open source, maintained by the OWASP Foundation. You only invest your time standing it up. BBLabs has a single PRO+ plan from €7.99/mo (or €74.99/yr, or €149.99 one-time lifetime), with no commitment and cancel-anytime, plus a free Academy to start without paying anything. Each one offers something different for its cost: Juice Shop is a free, generic challenge app; BBLabs is curated content from real reports, in Spanish, with writeups, live labs and weekly updates.

Is Juice Shop in Spanish?

Juice Shop's interface supports several languages, but the learning material, the guides, the community writeups and the ecosystem around it are mostly in English. BBLabs is built from scratch for the Spanish speaker: labs, writeups and a free Academy with 16 vulnerability categories, all in Spanish. If language is a barrier for you, that difference shows; if you're comfortable in English, Juice Shop is an excellent free resource.

Does Juice Shop prepare me for real bug bounty?

It's very good training for the OWASP Top 10, but it stays in challenge-app territory. Juice Shop teaches you to exploit vulnerabilities in an environment designed to be hacked and gamified, which is great for learning. Real bug bounty is about finding those bugs in complex production applications, understanding why they were paid and replicating the full chain. That's where BBLabs fits: its labs come from real reports, bring the writeup of how it was exploited and how much was paid, and its free Academy covers the theory. Combine Juice Shop to gamify the fundamentals with BBLabs for the jump to real cases.
