01
Infrastructure already handled
Start from a managed stack instead of stitching together networking, storage, certificates, and runtime services by hand.
U-CTF, because it's YOUR CTF.
Deploy shared or instanced challenges, upload your themes and plugins, and ship with storage included. No infrastructure to assemble by hand.

What you get
- Managed CTFd infrastructure
- Shared & instanced challenges
- Theme & plugin delivery
- Custom domain with TLS
- 10 GB included storage
- Git-synced challenge delivery
Everything your event needs. Nothing extra to build.
Built for organizers who want to focus on great challenges, not on maintaining the stack running them. Customization, deployment, storage, and operations in one workflow.
02
Theme and plugin delivery
Upload the visual identity and platform extensions your event needs without building a bespoke deployment workflow.
Deploy challenges the way the event actually needs them.
Some challenges belong in one shared service. Others need isolated infrastructure per team. Both patterns are supported, you're not locked into one model.
A
One container for everyone
Shared challenge
Use a shared challenge deployment when a single service is enough for every team. It keeps operations lean and is a good fit for classic web and service-style challenges.
- One running service for the whole event
- Simpler resource footprint
- Useful when all teams can interact with the same environment
B
Isolated environment per team
Instanced challenge
Use instanced deployments when each team needs a clean environment. Better when the challenge can be altered, exhausted, or solved in a way that should not leak state across teams.
- Fresh environment for each team
More challenge infrastructure, lower price point.
U-CTF's basic plan is built for organizers who need per-team instanced challenges and full container control. Capabilities hosted CTFd reserves for higher tiers.

Ship challenge assets quickly, then decide how much of the storage story you want to own.
U-CTF includes storage from the start, so you can publish challenges, bundle event assets, and keep customization files moving without blocking on separate infra work.
- 10 GB storage included for challenge and event assets.
- Bring your own credentials when your organization needs a custom storage path.
- Keep themes, plugins, and challenge artifacts closer to the event workspace.
Included by default
10 GB
Enough room to get a competition moving, with a clean path to your own credentials when the event setup calls for it.
