Velyr
an AI agent that finds and fixes conversion leaks on your site

What is Velyr?
Velyr is an AI-powered growth agent that automatically identifies and fixes conversion problems on React, Next.js, and Vite websites deployed on Vercel. The tool finds your site's #1 conversion problem each week based on PostHog analytics data (traffic, bounce rate, scroll depth, and click behavior) and writes the fix as a GitHub Pull Request with a Vercel preview link.
The platform operates through a simple 4-step workflow: every Monday it scans your analytics and GitHub repo, identifies the highest-impact conversion problem across your full funnel, opens a Pull Request with the fix, and sends you a Telegram message summarizing the problem and proposed solution. You approve changes with a single YES reply on Telegram, and nothing merges without your explicit approval.
Velyr includes an automatic 48-hour rollback safety net that reverts changes if bounce rate spikes by 15 percentage points or more. It also features competitor tracking and Brand Guardrails with written rules the agent must respect to reject off-brand suggestions. The tool is specifically designed for indie hackers, solo founders, and small SaaS teams who want ongoing conversion optimization without hiring a CRO agency.
Unlike most conversion tools that only provide reports and dashboards of suggestions, Velyr writes actual code changes and opens them as Pull Requests within your existing GitHub, Vercel, and PostHog workflow. This means there is no new platform to migrate to, and you get real code shipped weekly rather than just recommendations you have to implement yourself.

Frequently asked questions about Velyr
Do I approve every change?
Yes. Nothing merges without your explicit YES reply over Telegram, and you review the exact code diff in the Pull Request first before approving.
What if a fix makes things worse?
Velyr checks site-wide bounce rate 48 hours after each merge and auto-opens a revert Pull Request if it rose by 15 percentage points or more.
Is my code safe?
Velyr only proposes changes as Pull Requests on your own GitHub repo. You review and approve before anything merges — it never pushes to your default branch on its own.
What analytics data does Velyr use?
Velyr reads your PostHog analytics including traffic, bounce rate, scroll depth, and click behavior to identify conversion problems.
Which websites are supported?
Velyr is built for React, Next.js, or Vite sites deployed on Vercel with a GitHub repository. Site builders that don't expose source code like Shopify, Wix, Squarespace, and Webflow are not supported.
How often does Velyr ship fixes?
Every Monday the agent reads your analytics and scans your GitHub repo, then identifies the single highest-impact conversion problem and ships it as a Pull Request.
What is Brand Guardrails?
Brand Guardrails are written rules the agent must respect, so off-brand suggestions are rejected before they reach you for approval.
Can I cancel during the trial?
Yes, you can cancel anytime during the 14-day free trial without being charged, and you can cancel anytime afterwards too.
Does Velyr work with other analytics tools?
Velyr specifically uses PostHog analytics for traffic, bounce rate, scroll depth, and click behavior data. Other analytics tools are not mentioned as supported.
What happens if I reply NO to a fix?
If you reply NO to skip a fix, nothing merges. You can skip any Pull Request and the agent will work on the next highest-impact problem the following week.
