Questions, answered.
Is Rectify a good PostHog alternative?
If you need analytics plus the rest of the job, yes: support with live chat, Slack and email, feedback boards, a roadmap, a changelog, a help centre and uptime. If deep product analytics, flags and experiments are the main need, PostHog goes further there.
How does pricing compare?
PostHog is free every month up to each product’s limit, then billed per use, with unlimited team members. Rectify Build is a flat $29 a month for 3 seats, and AI runs at your provider’s price with zero markup.
What does agentic mean here?
Quanta doesn’t only answer questions. It does the work: it triages bug reports, moves roadmap cards, writes the changelog, starts code scans and opens draft fixes. Anything that changes your data waits for a person to approve it.
Can I use both?
Yes. Some teams keep PostHog for deep product data and use Rectify for support, feedback, the roadmap, uptime and bug fixes. The Idea plan is free for good.
