Lakera Alternative: SafePrompt vs Lakera Guard (2026)

You found Lakera, liked it, then hit the "contact sales for pricing" wall. You are a solo founder or a small team, not a procurement department. The good news: you do not need an enterprise contract to block prompt injection. Here is the honest head-to-head so you can decide.

We are biased, SafePrompt is our product, so we will be specific about when Lakera is the right call. If you want the full landscape first, see our roundup of the best prompt injection detection tools. If you are on Microsoft's stack, see the Azure Prompt Shields alternative.

    'Content-Type': 'application/json'
  },
  body: JSON.stringify({ prompt: userInput })
}).then(r => r.json());

if (!safe) throw new Error('Injection detected: ' + threats.join(', '));
// Safe to call OpenAI, Anthropic, Gemini, anything

The bottom line

Frequently asked questions

Is SafePrompt as accurate as Lakera?

SafePrompt achieves above 95% detection accuracy on our benchmark suite. Lakera does not publish exact accuracy figures, but both tools perform similarly on standard prompt injection attacks. For another managed option, see our Azure Prompt Shields alternative comparison.

Can I migrate from Lakera to SafePrompt?

Yes. SafePrompt is one HTTP POST to /api/v1/validate with an X-API-Key header, returning a safe boolean and a threats array. Most teams complete migration in under an hour.

Does SafePrompt offer enterprise features?

SafePrompt's Business tier ($99/month) includes priority support, custom rules, and higher rate limits. SOC 2 compliance is in progress. Contact us for enterprise needs beyond the standard tiers.

What about LLM Guard (open source)?

LLM Guard is a free, self-hosted option. The tradeoff is maintenance burden: you own updates, scaling, and security patches. SafePrompt handles all of this for $29/month.
