Indie Unity projects stall for a boring reason: the wrong dependency channel. Some systems belong in Package Manager. Others belong on the Asset Store. Mixing them blindly creates duplicates, update pain, and license confusion.
This guide is a practical split for indie teams — what each channel is for, when to use which, and a workflow that keeps projects maintainable.
Table of Contents
What each channel is for
Package Manager (UPM) is for engine-adjacent modules: Input System, Cinemachine, URP/HDRP, Timeline, Test Framework, and Unity-verified packages. Updates follow package versions and project manifests.
Asset Store is for third-party content and tools: character packs, VFX libraries, save systems, editors, templates, and specialist SDKs. You import .unitypackage content (or UPM-bridged store packages) into project folders you own and maintain.
Use Package Manager when
- You need camera, input, rendering, or timeline features tied to Unity releases.
- You want reproducible installs via
manifest.json/packages-lock.json. - Multiple teammates must get the same dependency without manual package downloads.
- The feature is already first-party and maintained by Unity.
Use the Asset Store when
- You need art, audio, VFX, or a production tool Unity does not ship.
- You want a full gameplay framework (dialogue, inventory, controllers) with examples.
- You are buying specialized middleware wrappers or niche editor workflows.
- You accept that updates and support are publisher-driven, not Unity-core.
Common overlap traps
- Cameras: prefer Cinemachine from Package Manager before buying another camera stack.
- Input: Input System package first; buy Rewired/other only if you need their specific feature set.
- Post-processing / URP volumes: use pipeline packages before stacking old image-effect assets.
- Duplicates: two tween libraries, two save systems, or two inventory frameworks will fight you.
Indie workflow that scales
- Lock render pipeline and Input System via Package Manager on day one.
- Add only Asset Store packs that unblock a vertical slice (controller, one environment, one audio kit).
- Record licenses and versions in a simple project notes file.
- Upgrade Unity packages on a schedule; upgrade store assets one at a time with a backup branch.
- Delete unused demos/scenes from imports to keep the project searchable.
Quick decision cheat sheet
Need engine feature? Package Manager.
Need content or a third-party system? Asset Store.
Not sure? Search Package Manager first. If Unity already ships it, do not buy a parallel stack.

Wrap-up
Keep Package Manager for the spine of the engine. Use the Asset Store for muscle and skin. That split keeps updates sane and prevents “why do we have three input systems?” postmortems.
