The era of "it works on my machine" has come to an end as local development environments have evolved significantly over the years. In the 1990s, developers had to manually set up and manage their own systems, leading to deep technical understanding and creativity. The 2000s saw the rise of standardized local development environments through *AMP stacks, which provided one-click installations for web servers, databases, and frameworks. Docker introduced containers in the 2010s, revolutionizing local development with lightweight, isolated environments that package everything an application needs to run. Today, hosted environments have become the norm, with cloud services providing fully managed Postgres instances, developer-friendly workflows, and collaborative features like branching and real-time debugging sessions. The future of local development is shifting towards ephemeral, cloud-native tools that blur the lines between development, operations, and collaboration.
