In plain English
A simple, locked-down Canva for small organizations with no designer. An admin sets the brand colours and logos once, then anyone on the team can arrange text and images on a page and export a clean PDF without breaking the look.

Sattend
A custom Canva for small organizations without designers. Admins lock brand backgrounds, fonts, and colors. Team members create on-brand graphics inside those guardrails without breaking the visual identity.

Why I built this
Most small organizations (clubs, communities, internal teams) don't have a designer. They still need to make event banners, social posts, member graphics. The usual answer is Canva, but Canva is built for individuals making whatever they want. Brand drift is the default.
I wanted the opposite: a tool where an admin sets up a brand preset (locked backgrounds, whitelisted fonts, disabled features) and team members fill in the variable parts. On-brand by default, off-brand by impossibility.
Shipped April 2026 and tested it on myself. Never promoted it publicly because I haven't found the right organization champion yet. Pre-launch, but functionally complete.
Brand identity
Squiggle-mark lockups designed in-house. The squiggle stands for the freedom users have inside the locked brand container.




How it works
Choose a background
Start with a solid color or linear gradient (angle adjustable). Upload a custom background image with blur and overlay controls.
Add images
Upload photos and logos to the canvas. Crop, scale, add borders, and adjust blur. Images are stored in Supabase Storage.
Add text and shapes
Place text layers with customizable fonts (lazy-loaded from Google Fonts), sizes, weights, and colors. Draw rectangles, circles, lines, and stars.
Arrange with layers
Reorder elements in the layers panel. Multi-select with Ctrl+Click, group with Ctrl+G. Full undo/redo history (30 steps).
Export
Download your design as a JPG. Save-to-gallery and template-saving are disabled today, coming soon.

Under the hood
An admin sets up the brand once, locking the backgrounds, fonts, and colours, and then team members only see the choices they are allowed to make. Going off brand is not just discouraged, it is simply not possible.
Each person only ever sees and edits their own work, and those permissions are enforced on the server, not just hidden in the screen, so nobody can sneak past them.

Common questions
Is it free?+
Yes. Free Google sign-in, no install, no paywalled features. Built on Supabase + Vercel free tier, costs nothing to use today.
Why use this instead of Canva?+
Canva is built for individuals: maximum freedom, brand drift by default. Sattend inverts it: admins lock backgrounds, whitelist fonts, and hide features per preset, so members can only build inside the brand. On-brand by default, off-brand by impossibility.
Who is it for?+
Small organizations without a dedicated designer (clubs, communities, student orgs, internal teams) that need event banners and social posts without policing every output.
Can I bring my own fonts?+
Not yet. Fonts are lazy-loaded from Google Fonts, with admins whitelisting a subset per preset. Custom font upload is on the roadmap behind a licensing check.
What can I export?+
Today, JPG only. PNG and SVG are on the roadmap.
Is my data private?+
Yes. Google OAuth via Supabase, with Row Level Security enforced at the database layer and three roles (User, Admin, Super Admin) verified server-side. A client can't escalate by editing local state.
What I learned
- ·Hiding a feature entirely beats showing it greyed out. A disabled button makes people ask why they cannot use it, while a feature that simply is not there raises no questions at all.
- ·Finishing a tool is not the same as having anyone use it. The product is technically done, but without a real organisation behind it, that is research, not a launch.
- ·The biggest gap was never the code, it was finding the first real customer to build around. That is the thing I would chase sooner next time.
What's next
Honest roadmap. Things I know are gaps, in priority order.
Find a champion organization
The biggest gap isn't code, it's adoption. The next move is convincing one small org with brand-control pain to actually use it, then iterating against real feedback. Without that, every roadmap item is speculation.
More export formats
Today only JPG. PNG for social (transparency), SVG for designers (vector edit), PDF for print, all on the roadmap. Each one is a separate canvas-to-format pipeline.
Custom font upload
Google Fonts cover most cases but not brand-specific custom faces. Needs upload + licensing checks before being safe to ship.
Mobile editor
Today the editor is desktop-only (canvas interactions assume mouse + keyboard). A mobile-first variant would unlock on-the-go content creation, but is essentially a second UI.
