"We used Sitechecker for two years. Flatline is faster, doesn't feel bloated, and the support is actually a human who understands UK local business. That's worth the switch alone."

Common questions
Is Flatline faster than Sitechecker?+
Yes, consistently. We audit in ~15 seconds. Sitechecker takes 30-45 seconds. For monthly tracking with lots of clients, that adds up to significant time savings.
Can I import my Sitechecker reports into Flatline?+
Not directly, but run a Flatline audit of the same site today and you'll have a baseline for comparing future months. The scoring is different but the insights are complementary.
What if I need competitor analysis?+
Sitechecker has basic competitor checks. Flatline doesn't yet. If that's critical, keep Sitechecker for that feature and use Flatline for your own site audits.
Does Flatline have API access like Sitechecker?+
Yes, on our Agency plan ($199/mo). You can automate audits and integrate results into your own tools.
