# Open-Source Guardian Architecture The idea for the Managed Guardian Service (MGS) was born out of Envision Blockchain’s work with the [open-source version](https://github.com/hashgraph/guardian) of the Guardian. Envision partnered with Hedera almost two years ago with the goal to build and maintain an open-source platform that allows for the creation and tracking of digital environmental assets. Envision Blockchain noticed an opportunity to take their experience as builders and maintainers of the open-source Guardian to create a hosted offering for the ESG industry. The goal is simple: provide a SaaS which allows application builders to focus on building their applications and policies instead of spending time configuring and managing the Guardian. Users of MGS won’t notice a difference with regard to the MGS offering and the open-source version, because almost all of the core open-source Guardian components will always be the same --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
