Ship the first version
From an idea or an existing repository: requirements, mockups, stories, pull requests with tests, and a deployment to your own hosting. That part every tool can do. It is the beginning.
For anyone whose v1 exists and v2 is the problem
The second feature is where AI tools give up. Ours doesn’t.
Prototype builders are brilliant at the first version and lost by the third. VrittOS plans every new feature against the code that already exists — same repository, same backlog, same project — and delivers it as a tested pull request.

How the tenth feature works like the first
Describe the next feature
The planner reads the requirements it already wrote, the backlog it already built and the files that have merged so far. It asks only what it cannot infer, then writes stories against your existing modules.
It lands in the same repo
Stories become pull requests on feature branches, with tests, in the codebase you have — extending the services and screens that exist rather than starting over beside them.
Keep it green
CI results sync back. When a merge turns main red, a triage agent works out why and offers you a fix. Open pull requests are rebased when a sibling merges, so the queue never rots.
Why context has to accumulate
A prototype tool starts from zero every time you open it. A delivery platform remembers what it built, why, and where — and that memory is what makes feature five as cheap as feature one.
The increment contract
Every new feature is planned with the prior requirements, the built backlog, the merged files and the fixed tech stack in hand. Nothing is re-explained; nothing is re-invented.
No slot tax
A feature joins the project it belongs to. It never counts as a new project, so a product with forty features is still one project on your plan.
Conflict-aware
When one pull request merges, the open ones that now conflict are rebased and re-verified automatically — you review clean diffs, not merge markers.
When main goes red
New work waits, the failure is triaged, and you get a decision to make with the evidence attached — not a raw CI link and a shrug.
Your hosting, your repo
Deployment workflows are committed to your repository and run against your own Vercel, Netlify, Railway, Render or Azure account. Leave tomorrow and everything still works.
Approval every time
Each feature passes the same gates as the first: you approve the stories before code is written and the pull request before it merges.
Common Questions
Does adding a feature create a new project?
No. It joins the existing project, backlog and repository, and it does not use a project slot on your plan. A project is the product; features are what it accumulates.
How does it know what has already been built?
From three things it wrote itself: the requirements from the previous run, the stories that were delivered, and the files each merged story touched. It also rebuilds its map of the code at implementation time, so changes made outside VrittOS are seen too.
Can my team keep using Cursor or Copilot alongside it?
Yes. It is your repository and your branches. VrittOS reads the current state of the code before each story, so hand-written changes are part of the picture, not a surprise.
What happens when two features touch the same file?
Stories declare the modules they affect, so the planner sequences the ones that overlap. If a pull request still conflicts after a sibling merges, it is rebased and re-verified automatically before you are asked to review it.
What does a feature cost?
The same per-phase credits as the first version — planning, stories and each pull request are priced the same whether it is the first feature or the fifteenth. There is no charge for it being an addition rather than a new project.
