### Overview of Overleaf

Overleaf is a collaborative LaTeX editor loved by researchers and tech teams. Their cloud version is available at [overleaf.com](https://www.overleaf.com/). It provides a full-featured online LaTeX editor. Howevery, Overleaf Common (SaaS version) has numerous feature limitations, and you have to tolerate *<mark style="color:red;">**10-second compilation times limit**</mark>* and expensive membership fees.

Although Overleaf offers an open-source community version (available on [GitHub: Overleaf](https://github.com/overleaf/overleaf)), it also has many limitations, for example:

{% hint style="warning" %}
Overleaf Community Edition is intended for use in environments where **all** users are trusted. Community Edition is **not** appropriate for scenarios where isolation of users is required because Sandbox Compiles are not available.

Without sandboxing, LaTeX compiles run with the same privileges as the container, allowing access to its filesystem, network, and environment variables. This creates a risk of data exposure or system compromise. Non-sandboxed compiles should only be used in fully trusted environments; for multi-user or production deployments, Sandbox Compiles are strongly recommended.

For more information on Sandbox Compiles see: [Sandboxed Compiles](/on-premises/configuration/overleaf-toolkit/sandboxed-compiles.md)
