Vibely is browser-only. No install, no local setup, no env vars to wrangle. The fastest path from “I want to build X” to “X is live at a URL someone else can open” is below.
1

Sign in

Go to vibely.sh and pick a sign-in provider — Google, SSO, or email. You’ll land in your personal workspace with a starter project ready to clone.
2

Pick what you're building

On the new-project screen, pick the surface that matches your idea. You can switch later.

Web app

SaaS, dashboards, CRUD, marketing sites. The default.

Mobile app

iOS + Android from one codebase. Ship to the stores.

Design

Visualize first, make real with one click. Slides, animations too.
3

Describe what you want, concretely

The more specific your first prompt, the better the first turn. Name the user, the data, and a feel.
“A CRM for solo consultants — contacts, deals with three stages, daily activity feed. Use Supabase auth (email + Google). Calm, professional, lots of whitespace.”
See Art of Prompting for the patterns that consistently produce clean first turns.
4

Answer 3–4 clarifying questions

Before writing any code, Vibely asks 3–4 short follow-up questions to pin down the niche, audience, primary user flow, and visual tone. Answer them honestly — even one-line answers dramatically raise the quality of the first turn and help the agent tailor the build to your exact use case instead of a generic template.
5

Watch it appear

Within ~10 seconds of your answers, a live preview URL opens in the right pane. The agent writes files; the preview hot-reloads as each one lands. By the time the agent stops, you have a working app you can click around.
6

Iterate

Keep prompting. Each turn touches only what needs to change — no rebuild from scratch.
  • “Add a kanban view to deals.”
  • “Make the sidebar collapsible on mobile.”
  • “When a deal moves to Won, post to Slack #wins.”
Click any element in the preview to edit it inline (“make this button orange”). For big changes, ask for a plan first: “plan multi-tenancy before writing code.”
7

Publish

Project menu → Publish. You’ll get a stable <your-slug>.vibelyagent.com URL in seconds. Add a custom domain in two minutes when you’re ready. See Publish for access controls, version rollback, and GitHub export.

​
What a good first session looks like

After one focused session (45–60 minutes), most people have:
  • A working web app at a vibelyagent.com URL
  • Auth, a database, and at least one real feature wired
  • The first design iteration past “default look” — something that feels like your taste
  • Custom instructions written, so every future project starts ahead

​
If your first attempt looks generic

That’s almost always a prompt problem, not a Vibely problem. Two quick fixes:
  1. Restart the prompt with a named user. “An ops dashboard for a fulfilment team that ships from three warehouses” is night-and-day better than “an ops dashboard.”
  2. Name three brand anchors. “Like Linear meets Notion meets Duolingo” gives the agent a specific aesthetic to aim at.
