SUMMARY

Malicious or misconfigured client is sending requests with a spoofed Host header that isn't in ALLOWED_HOSTS. This is a security feature working as intended.

Real issue High confidence
LIKELY CAUSES
  • Spoofed or misconfigured Host header from external client
  • Load balancer or proxy forwarding requests with wrong Host value
NEXT STEPS
  • Verify ALLOWED_HOSTS includes all legitimate domains
  • If the traffic is from bots, consider adding rate limiting

AI Triage
SUMMARY

A user tried to register with an email address that already exists in the database. The signup view creates users without checking for existing accounts first.

Real issue High confidence
LIKELY CAUSES
  • No uniqueness check before calling User.objects.create()
  • Missing form-level validation for duplicate emails
NEXT STEPS
  • Use get_or_create() or check User.objects.filter(email=email).exists()
  • Add a unique constraint validation message to the signup form

Less noise. More signal.

The same error happening 500 times shows up as one issue with a count. Fix it once, mark it resolved, move on.

Frequently asked questions

How long does setup actually take?
About 2 minutes. Install the SDK, add two lines, deploy. No config file, no agent process, no infrastructure.
Is this built for solo devs or can my team use it too?
Both. Free plan = 1 seat, unlimited projects. Starter = 5 seats.
How is this different from just checking my logs?
Logs tell you something happened. booboo tells you exactly what: exception type, line of code, local variables, request data. Plus grouping so you're not sifting through duplicates.
How is this different from Sentry?
Sentry is a great tool if you have a dedicated platform team to manage it. If you don't, you end up paying for features you'll never configure. booboo gives you the things that actually matter: stack traces, grouping, AI triage, alerts. Half the price, none of the complexity.
Can I use the free plan for a real production app?
Yes. 5,000 events/month, unlimited projects, AI triage. Enough for side projects and early-stage apps.
Where do alerts go?
Slack, Discord, or any URL via webhooks. Routing rules per project.
Do I need to change my code to capture errors?
No. The SDK auto-captures unhandled exceptions via middleware/global handler. You just initialize it.
Can I try it before paying?
Free plan has no time limit. No credit card required.
Where is my data stored? Is it secure?
Your data is hosted in the EU. PII scrubbing is built in per-project, and all webhook payloads are HMAC-signed. We take data security seriously.
What happens if I exceed my event limit?
New events stop being accepted until the next billing cycle. No surprise charges, no hidden fees. You can upgrade anytime to increase your limit.
What languages and frameworks do you support?
Python (Django, Flask, FastAPI) and JavaScript (React, Vue, Node.js). The SDKs auto-capture unhandled exceptions via middleware or global error handlers.

We use booboo.dev to monitor booboo.dev.

Your users shouldn't be your error reporters.
