Horizon UI
A component boilerplate with generative UI pieces included. The site returned a payment-required error.
A starting template, not a framework.
This one did not answer. Asked on 2026-09-04, and
the site refused an automated request. The entry stays because nothing here is deleted, and because a tool
that has gone is worth knowing about. The link above is not live.
What it is sold for
Unverified: the site would not answer.
Same shelf
The rest of ai assistants and agents, alphabetically. Sharing a category is a filing decision, not a relationship.
- Generates and hosts WordPress sites, with the build and the hosting sold as one product.
- Agent Shadow Brain did not answerListed as a background analysis agent. The repository returns 404.
- Assigns work to a group of agents and tracks it, treating them as a team roster rather than as one assistant.
- A TypeScript toolkit that puts one interface in front of many model providers, including streaming and tool calls.
- An agent that spends more compute at inference time on harder engineering problems rather than answering immediately.
- Pair programming in the terminal. Reads the repository, proposes edits, and commits them to git with a message.
- Amazon's original completion assistant. The name is retired and the address now serves Amazon Q Developer.
- Amazon's coding assistant, integrated with AWS accounts and services rather than with the editor alone.
