Penpot

Open-source design software built on web standards, so files are open formats rather than a vendor's binary.

The design tool you can self-host.

What it is sold for

Designing interfaces without a proprietary file format.

The rest of design and media, alphabetically. Sharing a category is a filing decision, not a relationship.

APITemplate.io

Generates PDFs and images from reusable templates over an API, so document rendering is not something you build.
Bytescale

File storage with image and video processing on the delivery path, so transforms are URL parameters.
Chakra UI

A React component system with accessibility and theming built into the primitives rather than layered on.
Cloudinary

Media storage with transformation and delivery, the long-standing default for images that must exist at twelve sizes.
Dyte

Real-time audio and video as a toolkit, so live features do not require running media infrastructure.
Figma

The design tool that moved interface work into the browser and made multiplayer editing the default.
Flatfile

Handles the customer data import: extraction, mapping, validation and the mess in the spreadsheet they sent.
ImageKit

Real-time image and video optimisation with a digital asset manager attached.
