Note Has it ever happened to you that you changed data on a test system and then realized: oh no, that's the live system. Well, to prevent that from happening (again), I created this extension.

Indicators marked **(opt-in)** are not part of the default configuration presets: either the extension configuration switch for them is off by default (CLI banner, backend theme), or they only ever do something once you [register them yourself](https://docs.typo3.org/p/konradmichalik/typo3-environment-indicator/main/en-us/Configuration/Index.html) (frontend image, HTTP response header, robots header, backend topbar). Everything else works out of the box. Note These environment indicators are mainly for development purposes (e.g. distinguishing between different test systems) and will not show on the live production site by default. They do show in `Production/Staging` and `Production/Standby`application contexts, where they help distinguish those systems from the live site. Indicators you register yourself, such as the [robots header](https://docs.typo3.org/p/konradmichalik/typo3-environment-indicator/main/en-us/Indicators/FrontendRobots.html), can still affect live production if you explicitly configure their triggers to do so. 🔥 Installation -------------- [](#-installation) ### Requirements [](#requirements) VersionTYPO3PHP3.x13.4 - 14.x8.2 - 8.52.x11.5 - 13.48.1 - 8.4### Composer [](#composer) [![Packagist](https://camo.githubusercontent.com/c3e19a8abc2067a347a6430aac1a4ab7ebf83c1a6d34975fb00392f1dcb3b6ed/68747470733a2f2f696d672e736869656c64732e696f2f7061636b61676973742f762f6b6f6e7261646d696368616c696b2f7479706f332d656e7669726f6e6d656e742d696e64696361746f723f6c6162656c3d76657273696f6e266c6f676f3d7061636b6167697374)](https://packagist.org/packages/konradmichalik/typo3-environment-indicator)[![Packagist Downloads](https://camo.githubusercontent.com/f54ba4ca2ae0cec44f0f342b24e794c6db71c511b51d2e0e07a97bbc529d64e8/68747470733a2f2f696d672e736869656c64732e696f2f7061636b61676973742f64742f6b6f6e7261646d696368616c696b2f7479706f332d656e7669726f6e6d656e742d696e64696361746f723f636f6c6f723d627269676874677265656e)](https://packagist.org/packages/konradmichalik/typo3-environment-indicator) Use the following composer command to install the extension: ``` composer require konradmichalik/typo3-environment-indicator ``` ### TER [](#ter) [![TER version](https://camo.githubusercontent.com/c8d0a07f09f09f4be1e8fe8bdb24482c86b5bb6ab91125af07d69ae23294f05f/68747470733a2f2f7479706f332d6261646765732e6465762f62616467652f7479706f335f656e7669726f6e6d656e745f696e64696361746f722f76657273696f6e2f736869656c64732e737667)](https://extensions.typo3.org/extension/typo3_environment_indicator)[![TER downloads](https://camo.githubusercontent.com/39c2d9b1b5cbe0e50645ad19086bc39fb108a18790fb84cff0cf3b6a1b18bee1/68747470733a2f2f7479706f332d6261646765732e6465762f62616467652f7479706f335f656e7669726f6e6d656e745f696e64696361746f722f646f776e6c6f6164732f736869656c64732e737667)](https://extensions.typo3.org/extension/typo3_environment_indicator) Download the zip file from [TYPO3 extension repository (TER)](https://extensions.typo3.org/extension/typo3_environment_indicator). 📙 Documentation --------------- [](#-documentation) Please have a look at the [official extension documentation](https://docs.typo3.org/p/konradmichalik/typo3-environment-indicator/main/en-us/Index.html). 🧑‍💻 Contributing ---------------- [](#‍-contributing) Please have a look at [`CONTRIBUTING.md`](CONTRIBUTING.md). 💎 Credits --------- [](#-credits) This project is partly inspired by the [laravel-favicon](https://github.com/beyondcode/laravel-favicon) package. ⭐ License --------- [](#-license) This project is licensed under [GNU General Public License 2.0 (or later)](LICENSE.md). ### Health Score 57 — FairBetter than 98% of packages Maintenance94 Actively maintained with recent releases Popularity34 Limited adoption so far Community13 Small or concentrated contributor base Maturity70 Established project with proven stability Bus Factor1 Top contributor holds 91.7% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
