The Verdict
Mattermost is built for devops teams and security conscious orgs, with a focus on messaging and channels. Photopea targets designers and students and leads with photo-editing and psd-support.
On pricing, Photopea is the clear winner for budget-conscious users — starting at $5/mo compared to $10/mo for Mattermost. That $5/mo difference adds up quickly for growing teams.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Bottom line: Photopea has a slight overall edge — but if self-hostable matters most to you, Mattermost may still be the right call.
