Smart Lower Thirds is a fully featured lower thirds plugin for OBS Studio that lets you create, customize, and automate beautiful broadcast-style overlays without any external files, third-party tools, or browser-source hacks.

This plugin is built for streamers, event hosts, educators, podcasters, and professional studios who want clean, animated, and reliable lower thirds that integrate directly into OBS.

Note: This plugin has currently only been tested on OBS Studio 32.0.2 (Windows 11, 64-bit). The macOS and Linux builds were generated through GitHub Actions, so I cannot guarantee that everything will run smoothly on those platforms.

To build custom templates, please visit https://mmltools.github.io/smart-lower-thirds/#placeholders and https://mmltools.github.io/smart-lower-thirds/#templates for a full description of the placeholders required to make your template work correctly.

This plugin is free and open-source; however, you can support its development by purchasing custom templates from my shop: https://ko-fi.com/mmltech/shop.

✔ Unlimited Lower

Create as many lower thirds as you need.
Each one includes its own title, subtitle, avatar, animation, colors, fonts, and behavior options.

✔ Professional Settings

Full control over:

Animation in/out (Animate.css support)
Typography & colors
Avatar/profile picture
Position presets & custom offsets
Auto-hide timers & visibility rules
HTML & CSS template editing

✔ Scene Binding & Hotkeys

Trigger lower thirds with OBS hotkeys or automatically show them when entering a scene.
To keep overlays clean, the plugin hides all other lower thirds when one is triggered
but you can still manually enable multiple lower thirds from the dock when needed.

✔ Import & Export Templates

Share lower thirds as .zip template packs, powered by minizip.
Includes layout, CSS, animations, colors, and more.

✔ Perfect For

Interviews & talk shows
Professional presentations
Esports & competitive events
News-style layouts
Tutorials and webinars
Branded social tags & callouts

Dock And Settings

Installation

Just install the plugin, enable the dock, and add the Browser Source once.
Everything else is done inside OBS no external dependencies.
