At BiteSite, a small custom software agency, they use Ruby on Rails and React for web and mobile applications. They initially used Heroku's free plan but encountered performance issues due to server spinning down after 30 minutes of inactivity. To address this, they turned to New Relic, which helped them monitor availability and identify performance problems. With New Relic, they can track transactions automatically, providing actionable insights on where performance issues lie. This enables them to quickly implement solutions, validate changes, and improve overall application performance. The agency appreciates the value New Relic delivers, particularly for small businesses with limited resources. They use the free tier of New Relic, which provides a clear roadmap for fixing issues, resulting in immediate impact and improvement in their development process.
