Beta Limits
UltiStackr is currently in a private web beta. The beta includes the core team-management, playbook, practice, schedule, game-day, communication, and notes workflows, with a few access and operational limits while the product is still being tested.
Access
Beta access requires an invite code.
- New users enter an invite code before creating an account.
- Signed-in users without beta approval are sent to the beta access screen.
- Invalid or expired invite codes cannot be used.
- Users without an invite code can join the waitlist.
Beta invite codes are separate from team invite codes. A beta invite code grants access to create an UltiStackr account during the private beta. A team invite code adds a signed-in user to a specific team.
Platform Availability
During beta, UltiStackr is available on the web.
- Use a modern desktop or mobile browser.
- Chrome, Edge, and Firefox are recommended for the most reliable browser notifications.
- Safari support can vary, especially for browser notifications.
- Native Android and iOS apps are not available yet.
Team Invite Sending Limits
To protect the beta environment and reduce accidental email bursts, team email invites are capped per team:
| Limit | Cap |
|---|---|
| Pending email invitations | 100 |
| Email invites per minute | 10 |
| Email invites per day | 75 |
| Email invites per week | 250 |
If a team reaches one of these caps, new email invites are blocked until the relevant window resets or pending invitations are accepted, canceled, or cleaned up.
Team invite links and 5-character team invite codes are still useful for onboarding groups because players can join from the shared link or code instead of requiring staff to send every invitation by email.
Sign-In Protection
Email/password sign-in has a short lockout after repeated failed attempts.
- After 3 failed attempts, sign-in is locked for 15 minutes in that browser.
- The lockout is stored locally in the browser.
- Successful sign-in clears the local attempt counter.
Google sign-in is handled through Google and may have its own account-protection checks.
Upload Limits
Some uploads are size-limited during beta:
| Upload type | Limit |
|---|---|
| Note image selected in the browser | 10 MB before compression |
| Stored note image after compression | 500 KB |
| Play audio attachment | 500 KB |
For best results, use compressed JPG or PNG images and keep whiteboard photos or screenshots cropped to the relevant area.
Browser Notifications
Browser notifications require browser support and permission.
- Each browser registers separately.
- Notifications are delivered only to browsers where you are signed in and have granted permission.
- Do Not Disturb, Focus mode, browser settings, or operating-system notification settings can prevent delivery.
See Push Notifications for setup and troubleshooting.
Changing Limits During Beta
Beta limits may change as the product scales. If a limit blocks a real team workflow, contact the UltiStackr team with the team name, what you were trying to do, and the error or cap you hit.
