Let's speak the same language:


Here is the list of the technical terms.


The name of the company but also we call "Flayyer" every created dynamic template. As a company we are composed by two main domains:

  • β€” Main service with dashboard, billing, account management and it's much more user-friendly.
  • β€” "Og:Image as a Service" rendering server.


The machine-friendly version of a text. Example: Hello there! as slug would be hello-there.


This is the most important thing about Flayyer. This is in reality a webpage (HTML, CSS and JavaScript) acting as a template to create dynamic images . What is great about this templates is that you can use them to generate infinite amount of images based on variables.

For developers and engineers: a template is a web component (React, Vue, etc). To develop templates you can start a project following this section. Every template has a name corresponding to the name of its file (similar to Next.js and pages).

Take a look at this example, here we have a template with multiple variables and some of all the possible outcomes:



These templates receives variables as input and renders images based on those inputs. This is way more smarter than other image services whom only allows to compose images, add watermarks, etc. You can do all of that and even more with custom login and your own styles.

Variables are passed through the unique URL of a flayyer as queryparams. Eg: This is an actual URL of a Flayyer with a param title:

Inside the component it looks like this:

import React from "react";
export default function DemoTemplate({ variables }) {
const title = variables.title; // πŸ‘ˆ variable from queryparams
return <h1>{title}</h1>;

To read more about variables and how to support objects and array go to Complex variables.

Deck or Project#

A deck β€”also known as "project"β€” is a collection of Templates. The idea of a deck is being able to share common styles, components and code between many templates. Each deck is identified by a slug.

Tenant or Company#

Every user belongs to an organization. We call this entities "tenants" or "companies" for simplicity. Each tenant is identified by an unique slug, eg: my-company. Each tenant has many Decks.

URL anatomy#

Every URL is built around this schema. For variables refer to Variables and Complex variables.

  • :tenant β€” is the Tenant's slug
  • :deck β€” is the Deck's slug
  • :template β€” is the Template's slug
  • :extension β€” the extension of the rendered image
    • Possible values: png, webp, jpeg (jpg is an alias)
    • Defaults to jpeg.
  • :version β€” The version control number of your deck.
    • Defaults to _ which means latest version.
    • Omit to always use the latest version (recommended).

Please note that :tenant, :deck and :template are always required, everything else is optional.

Short format#

Shortest form: always latest version and defaults to .jpeg format.
# Example:

Long format#

Longest form: explicit version and extension.
