How Felt Ships 15+ Times a Day on Render

Felt, a web platform for creating and collaborating on maps, emphasizes rapid deployment as a core aspect of its engineering strategy, often executing more than 10 deployments a day to remain responsive to customer feedback. This rapid iteration is facilitated by using Render's preview environments, which allow each pull request to become a standalone infrastructure, enabling comprehensive product testing and development. Key principles such as "Day 1 Deploys" and "PR Reviews" are integral to their approach, ensuring new engineers can contribute quickly and efficiently, while human-in-the-loop automation balances automation with manual oversight to maintain data security and reliability. The use of feature flags and a structured pull request etiquette further supports their fast-paced deployment environment, fostering a culture where engineers are encouraged to make manageable changes and test them thoroughly. Felt's commitment to speed aims to enhance its position as a leading map-making platform by quickly delivering innovations to users and reducing the gap between user needs and product offerings.
