README
Context Area - Fast, Smart Prompting for Devs
[](https://x.com/janwilmake/status/1980588668826902890)
Goals
Create the best possible Cloud-Based Context Engineering Experience for Developers that can be self-hosted (on Cloudflare)
- Easy to Share configurations and results with team
- Good MCP integration
- Strong Focus on Ease of use and Accessibility
- Edit Flow > Iterative Messaging
- URL Expansion with realtime insights (tokens, mediatype)
- Prompt Check (for OG, but also for missing context)
- Full Result is URL, each codeblock is URL
- Painpoint: Prompting workflows are very private, sharing functionality sucks. Visibility is value. Help devs share and monetise their learnings.
- Creating the best API for stateful chat completions
- Creating better ways of LLMs using tools
- Easy interface for chat completions standard
- X Login -> user-owned results, user payouts.
- Easy way to create "agents" that have many MCPs (by default)
- Integration with OpenRouter to make it super generic
Non-goals
We are not aiming to match the UX non-technical folks need in any way.
- Chat history
- Inline previews
- Styles
- Integrations
- Uploads
- Tools
