The term "open-source development platform" initially applied to open-source software(OSS). Open-source software is code that is intended to be openly accessible, meaning that anyone can view, change, and distribute it as they see appropriate. Peer review and community output are used to create open-source softwarein a decentralized and inclusive manner. Because it is created by communities rather than a single open-source software developer or creator or business, open-source software is frequently less expensive, more adaptable, and has a longer lifespan than proprietary software.
