Full plan & living docs
PRD, personas, architecture, and roadmap — generated with your app and kept current as it evolves.
Turn your idea into
a real product
Describe what you want to build. OneSpark plans it, designs every screen, builds the full-stack app, and helps you test and iterate — all in one place.

How it works
From idea to running product
One flow carries your idea through market analysis, planning, design, refinement, roles and compliance, documentation, and publishing — nothing gets lost between tools. Testing and fixes happen the same way, in the built-in QA workstation.
An AI roadmap with real docs — features, flows, personas, and architecture, organized into phases with a thumbnail for every screen before a line of code exists.
Cadence's roadmap: phases, feature cards, and a live design thumbnail on every feature.
Real output
Every screen designed for your idea, not a template
Three different generated apps, three different design styles — Cadence (physical-therapy clinic ops), Beacon Fleet (solar field-service dispatch), and Ledgerline (freelancer money workspace), all from the same flow.
Capabilities
Everything you need to ship
Not a toy for throwaway demos — a platform that carries an idea all the way to a real product.
Pixel-real screen designs
Every screen designed in your brand — the real look of your product, not grey wireframes.
One-click full-stack build
Frontend, backend, and database come together into a running product — deployed and clickable.
Integrated QA & ticketing
Test runs, tickets, and automatic fixes in a built-in QA workstation — quality is part of the flow.
Team roles & collaboration
Invite your team, assign roles, and share progress with clients — everyone sees the same product.
Refine anything by chat
Ask for changes in plain language — plan, designs, and code stay in sync automatically.
What you can build
If you can describe it, you can ship it
OneSpark generates real full-stack web applications — with auth, data, and the workflows your idea actually needs.

Integrations
Speaks to the tools you already use
Connect the services your product actually needs — payments, auth, monitoring, email, and more — right from the plan.
Security & your data
Your product stays yours
Serious about the boring parts, so you don't have to be.
Isolated workspaces
Every project runs in its own isolated worker — your app, your data, your sandbox.
You own the output
The plans, designs, and code generated for your project belong to you — build on them anywhere.

FAQ
Questions, answered
The short version of everything people ask before they start building.
OneSpark is a product-building platform. You describe an idea in plain language and it turns that idea into a planned, designed, working full-stack application — with the documentation, screens, and quality checks a real product needs.
Four steps in one flow. First OneSpark plans your product: features, screens, user flows, and docs. Then it designs every screen in your brand. Then it builds the app — frontend, backend, and database. Finally, the built-in QA workstation runs tests, files tickets, and fixes issues while you iterate by chat.
Web applications of most shapes: marketplaces, booking systems, SaaS dashboards, internal tools, client portals, learning platforms, delivery services, and more. If you can describe it, OneSpark can plan it — mobile apps are on the roadmap.
No. You work in plain language from idea to launch. If you do code, you still get real, structured output — a genuine full-stack application, not a locked-in prototype.
Yes — that is the point. Ask for changes in chat at any stage and OneSpark applies them while keeping everything in sync: the plan, the designs, the docs, and the code all move together.
Early access to the full flow — planning, design, build, and QA — with generous limits while we are in beta. Beta builders get new capabilities first and a direct line to the team.
Your projects stay yours and keep working. When we introduce paid plans they will be published on the Pricing page first, and early users will be the first to know — no silent switches.
Your ideas, files, and projects are private to you and your team. Attached context files are used only to build your product. You can delete a project — and everything in it — at any time.
