Open Source Development Software

Development tools provide the environments and utilities needed to write, debug, and deploy software. These tools automate repetitive coding tasks and manage the lifecycle of applications through integrated editors, command line interfaces, and visual workflow builders. This type of software serves programmers and system architects who need to build custom logic or deploy AI agents. Self-hosting these apps ensures that source code, API keys, and internal build pipelines remain on private infrastructure rather than relying on external cloud platforms.

This page lists 203 open source tools in the Development category. The most popular are n8n, OpenCode and Visual Studio Code. Most use the MIT or Apache-2.0 license, and 144 offer an official Docker image.
