Quotas & limits
Every quota and rate-limit value below is derived from the entitlements module at build time, so this page can never drift from what the server actually enforces.
Per-tier entitlements
| Free | Hobby | Pro | Unlimited | |
|---|---|---|---|---|
| Scans / month | 3 | 50 | 200 | Unlimited plan¹ |
| Projects (verified domains) | 1 | 1 | 5 | 20 |
| API tokens | 0 | 1 | 5 | 20 |
| Webhook endpoints | 0 | 1 | 5 | 20 |
| Active probes | no | yes | yes | yes |
| GitHub repo scans | no | no | yes | yes |
| Scheduled re-scans | no | no | ≥3h cadence | ≥6h cadence |
| Live threat detection | no | no | no | yes |
| Sharable reports | no | no | yes | yes |
| Retention | 7 days | 30 days | 90 days | 365 days |
| Team seats | 1 | 1 | 1 | 5 |
| Support | standard | standard | priority | dedicated |
¹ The Unlimited plan's scan quota is subject to fair use — see Terms. ² The project cap defaults to 20 active-monitoring domains at ≥6h cadence. Contact support@fixvibe.app to raise it in exchange for a longer scheduled cadence.
API rate limits
Every /api/v1/* and /api/mcp request is keyed on a hash of the bearer token and runs through two windows:
- Burst: 10 requests per second.
- Steady: 60 requests per minute.
- Per signed-in user: 30 scan submissions per 10 minutes — a soft cap above the per-plan monthly quota that absorbs bursts without exhausting the daily budget.
On 429, the response includes:
HTTP/1.1 429 Too Many Requests
content-type: application/json
retry-after: 47
x-ratelimit-limit: 60
x-ratelimit-remaining: 0
x-ratelimit-reset: 1715116200
{
"error": "rate_limited",
"message": "Token rate limit exceeded — steady (60/min). Retry in 47s.",
"retry_after_seconds": 47
}The window which tripped is named in the message (burst (10/s) vs steady (60/min)) so a client backoff can adapt.
Free plan scan rate limit (per IP/24)
On top of the per-org 3-scans-per-month cap, Free plan users face an additional per-IP/24 rate limit: 3 scans per rolling 24 hours per IP /24 block. The same limiter covers anonymous instant scans, which prevents farming Free quota through throwaway accounts on one IP. Requests exceeding the limit return HTTP 429 Too Many Requests with a Retry-After header.
Signup throttle (per IP/24)
5 successful sign-ups per IP/24 per 24 hours, to prevent automated Free plan account creation. Rate-limited callbacks redirect to /sign-in?error=rate_limited.
Retention
Scans + findings auto-purge per the table above. Anonymous one-shot scans expire 24h after creation. Audit logs retain for 18 months. Monitor snapshots prune to last 7 days plus the latest baseline per (domain, signal). Dismissed alerts purge after 90 days. All retention enforced daily by /api/cron/retention-cleanup.
