What is Velyr?
Velyr is an AI-powered growth agent that automatically identifies conversion rate bottlenecks in web applications by analyzing PostHog data and repository code. Instead of providing static reports, it autonomously generates and submits GitHub pull requests to apply specific performance-driven code changes.
- Best For: Indie hackers, solo founders, and small SaaS teams building with React, Next.js, or Vite.
- Pricing: €29/month after a 14-day free trial.
- Category: AI Marketing Tools
- Free Option: Yes (14-day free trial with all features).
The Problem Velyr Solves
Most SaaS founders and indie developers face a common dilemma: they have access to robust analytics, but they lack the time to manually translate that data into functional code improvements. You might know your conversion rate is dipping on a specific landing page, but identifying the exact UI or performance bottleneck, writing the fix, and testing it consumes hours of development time. This often leads to "analysis paralysis," where data-backed insights stay buried in dashboards while revenue growth stalls.
Solo founders and small engineering teams are the ones who suffer most, as they have to balance feature shipping with optimization work. Velyr bypasses this manual process by acting as an automated CRO (Conversion Rate Optimization) specialist that lives inside your GitHub repository. It bridges the gap between data analytics and production code by shipping actual, reviewable commits rather than just suggesting them.
In this tutorial, you'll learn exactly how to use Velyr to automate your conversion optimization workflow — step by step.
How to Get Started with Velyr in 5 Minutes
- Connect Your Accounts: Sign up for a Velyr account and link your GitHub repository and PostHog analytics integration.
- Configure Brand Guardrails: Define your design and content rules so the agent understands your brand voice and UI constraints before making changes.
- Link Your Telegram: Connect your Telegram account to receive weekly notifications and provide the necessary approval for code changes.
- Grant Repository Access: Allow Velyr to open pull requests in your repository, ensuring it only modifies code via tracked, reviewable commits.
- Monitor Your First Week: Wait for the following Monday, when the agent performs its first full-funnel scan and suggests its first conversion fix.
How to Use Velyr: Complete Tutorial
Step 1: Establishing the Data Foundation
Velyr relies entirely on the quality of data provided by your analytics stack. The agent pulls traffic metrics, bounce rates, scroll depth, and click behavior from PostHog to map the user journey across your entire application. Before you start, ensure your PostHog events are properly instrumented so the agent can accurately identify where your users are dropping off.
Step 2: Defining Brand Guardrails
One of the biggest concerns for developers using AI is the risk of the model pushing "off-brand" code or breaking existing design systems. Velyr addresses this by allowing you to set Brand Guardrails. You should input specific guidelines regarding your CSS patterns, UI components, and tone of voice, which the agent must reference before writing any code.
Step 3: Managing the Approval Flow
Once the agent identifies a high-impact conversion issue, it will push a pull request to your GitHub repository and send a summary to your Telegram. You will see a Vercel preview link alongside the explanation of the problem. Your job is to review the diff in the PR and reply "YES" via Telegram if you are satisfied, or "NO" to skip the change entirely.
Step 4: Leveraging the Safety Net
Conversion optimization carries inherent risk; sometimes a change intended to improve metrics actually causes a negative reaction. Velyr monitors your site for 48 hours following a merge. If the bounce rate spikes by 15 percentage points or more, the agent automatically initiates a rollback pull request. This ensures that even if you approve a change that turns out to be unsuccessful, you are protected from long-term performance degradation.
Velyr: Pros & Cons
| Pros | Cons |
|---|---|
| Ships actual code, not just suggestions. | Restricted to React, Next.js, and Vite stacks. |
| Human-in-the-loop ensures complete control. | Requires credit card for the initial free trial. |
| Automated 48-hour rollback for safety. | Not compatible with no-code tools like Shopify or Webflow. |
| Integrates directly into existing GitHub/Vercel workflows. | Only works on sites deployed via Vercel. |
Velyr Pricing: Free vs Paid
Velyr offers a 14-day free trial that provides full access to all platform features, allowing you to experience the entire lifecycle of an AI-generated conversion fix. This trial period is an excellent way to see if the agent's code suggestions align with your project's architecture before committing to a paid subscription.
After the trial, the service is priced at €29/month. This fee covers the weekly automated scans, pull request generation, and the safety rollback mechanism. Given that the tool acts as a "part-time" CRO developer for your SaaS, the pricing is highly competitive compared to the cost of manual consulting or external optimization agencies.

Who is Velyr Best For?
For Indie Hackers: It provides a way to maintain steady conversion growth without sacrificing time that should be spent on building new product features. You get the benefits of an optimization specialist while remaining a solo team.
For Solo Founders: It removes the technical friction of implementing small, data-backed experiments. You can focus on high-level strategy while the agent handles the code execution for minor landing page or funnel tweaks.
For Small SaaS Teams: It creates a standardized workflow for conversion improvements that are always documented as GitHub pull requests. This ensures that all team members remain aware of changes impacting user behavior.
Alternatives to Velyr
Traditional tools like VWO or Optimizely offer robust testing platforms but usually require you to manually implement the "winning" experiments into your codebase. Other options like PostHog itself allow for deep analytics but do not inherently write or ship code changes to your repo. Velyr is the better choice for developers who want to avoid context-switching between analytics reports and their IDE, as it closes the loop by turning insights directly into code.
Final Verdict: Is Velyr Worth It?
Velyr is a highly effective tool for developers who use modern stacks and want to systematize their conversion optimization. Its ability to ship code and provide an automatic safety net makes it a compelling choice for small teams looking to iterate faster.
