Colyna
Hosting, content publishing and commerce in one platform.
Colyna replaces the separate services behind a website, a readership and a shop. One instance runs the journal, the reader accounts and the shop of one creator or expert business, on its own domain and with its own records.

Why details matter
Trust is built in small moments: an answer that fits the question, a recommendation that still holds a month later, a promise the next page keeps. It is lost the same way.
Colyna keeps the writing and the offer in one place, so the explanation is there when the decision is made.

How Colyna is developed
Every moment where trust is won or lost is specified, tested and reviewed before release.
In practice
An example instance: the journal and shop of one atelier.





What Colyna is
Colyna brings together what a publishing business usually rents from several platforms: a place to publish, a relationship with readers, and a way to sell. Content, readers and orders are kept together in one application and one set of records, instead of being spread across services that each hold a part of the business.
Each business runs its own instance. Instances share no accounts and no data, and one business's settings, readers and orders are never visible to another.
Colyna is meant for creators and experts who publish, build a readership and sell products or paid content, and who want that business to stay in one place.
Building blocks
Journal and threads
Articles organised by topic and into ordered series, with feeds and pages prepared for search engines. Interface in English and German.
Reader accounts
Registration with email verification, sign-in, password reset, data export and account deletion that keeps order records without personal details.
Shop
Products, cart and orders with stock reservation. Card payments are being integrated.
Measurement
Visits counted by channel, source and campaign without cookies. Advertising and analytics tags load only after consent.
Controlled operation
Content, products and site settings change through reviewed releases, so every change can be traced and repeated.
Agent commerce
Planned: selling articles and products to AI agents through open payment protocols.
Principles
- Ownership
- Content, readers and orders belong to the business that runs the instance. They do not depend on a platform account that can be closed.
- One place for data
- All records are kept together and can be exported, backed up and moved as a whole.
- Privacy by default
- No third-party trackers without consent. Reader data exports never contain passwords or sign-in data.
- Reviewed changes
- Content and configuration go through reviewed releases rather than manual edits on a live system.
Status
Colyna is in research and development.
