Show HN: Caspian – Desktop app to build and launch small vibe-coded projects
caspian.md
For someone who vibe builds almost all the time, for both personal tools like investment or health dashboards or tools to help others, I found my projects scattered all over the place: researching with claude, writing context in notion, building with Claude Code, Devin, publishing in vercel, posthog for analytics and then others tools for GTM. Big part of brain energy drain was context switching, I wasn't very organized.
So I decided to build that lets me do all this from one place. I built Caspian. While most AI coding tools you use for vibe building stop at code, Caspian takes it all the way to users.
Caspian creates a "workbench" folder in your local machine where it puts all your projects so everything stays in one place and is also easy for your other tools to work with. There is a built in co-pilot, a context manager (.md files user can copilot both read/write), a one click publisher, analytics and an email outreach manager. Though the copilot uses API for processing LLM requests via open router (I make a little margin on top), it is pricy, so I build a standard "canvas" format that Caspian uses that your Claude/Codex or other tools you use also understand and can work with. Simply point them to https://caspian.md/docs and they'll learn to work with Caspian straight away, this is so that you're not tied to Caspian's co-pilot and if you prefer to use your own tools, you can do so.
Some other features I built around problems i found myself struggle with:
- Prompt refinement: Enter a vague prompt in co-pilot, caspian uses a cheap model to generate a detailed before starting the task.
- Preflight: It breaks down the task and tells you estimatedly, how much will it cost and how long will it take, before starting the task.
- Product and User context: Co-pilot has access to the two files so both you and Caspain has understand of your product and user.
- Code/No code: You can switch this button to dive into code or just stick with the vibes.
I hope it helps and you can build and launch a lot quickly. Feedback what's the most annoying thing when you vibe code?
