20FLOW

Build faster.
Keep full control.

Production-ready workspace with project memory.

Claude

Add a new pricing page and keep the existing design. Do not change the database.

Same project. Best model for each task.

BUILD ANYTHING

From idea to working product — without every model starting over

20Flow does not hand your project to a model as a disposable chat session. Your project lives in a persistent workspace, and every model works on the same files, memory and change history.

⌘

An AI agent that actually builds

Create websites, apps, dashboards, internal tools and APIs. The agent reads files, edits code and runs validation.

↔

Switch models without losing context

Start with Claude, move to GPT for a bug, then ask Gemini to review. Every model continues from the same Project Brain.

◈

Persistent Project Brain

Stores the stack, file structure, project rules, past decisions, tasks, routes and the last stable checkpoint.

✓

Safe edits before production

Every substantial change goes through a checkpoint, working tree and build/test. Failed changes never touch production.

⌁

GitHub stays in your account

Connect a specific repository through a GitHub App. Your code stays yours and access can remain scoped to one project.

☁

Cloudflare preview, then publish

Create a preview deployment, inspect the result, then approve production. Roll back to any previous checkpoint when needed.

ONE PROJECT MEMORY

The model can change. Your project memory does not.

Instead of depending on a GPT or Claude conversation history, 20Flow owns the project state and gives each model the precise context it needs.

✓ Relevant file tree and task files
✓ Project rules and protected areas
✓ Latest diff and stable checkpoint
✓ Design and architecture decisions
✓ Build/test status and remaining tasks

↔ Hand off to another model

The next model receives the issue, affected files, latest diff and project rules, then continues from the exact same point.

SAFE BUILD PIPELINE

20Flow builds, verifies and previews before production

Connect

Connect GitHub, choose a repository, then connect the matching Cloudflare project.

Understand

20Flow builds the Project Brain from your stack, files, rules and build commands.

Build

Describe the change in plain language and choose Auto, GPT, Claude, Gemini or another model.

Verify

Changes happen in an isolated workspace, followed by build/test and a clear diff review.

Preview

See a real preview before any production change is approved.

Publish

Only after approval: commit, deploy and keep a rollback path.

AI HUB

Not just Build — all your models in one place

Use Auto Router for everyday work, pick a model manually, or compare multiple answers side by side. One account, one usage layer and one toolset.

Auto

Smart routing

Routes the request to the best model for the task and target cost.

Manual

Choose your model

Use GPT, Claude, Gemini, Grok, DeepSeek or Mistral directly.

Compare

Compare models

Send one prompt to multiple models and inspect the results side by side.

BYOK

Bring your own keys

Use your own provider API keys and pay 20Flow for the workspace instead of hidden markup.

YOUR CODE. YOUR CLOUD.

20Flow helps you build — it does not hold your project hostage.

Your repository stays on your GitHub account and hosting stays on your Cloudflare account. If you stop using 20Flow, your project and infrastructure remain yours.

SAFE EDIT MODE

No random deletes. No silent risky changes.

Project rules stay consistent even when the model changes: no framework, database or environment changes without a clear reason, and no production publish without approval.

Frequently asked questions

Can I switch from Claude to GPT in the middle of a project?

Yes. 20Flow keeps project memory, files and history, so the next model continues from the same state instead of starting over.

Does 20Flow deploy directly to production?

Not by default. Changes can pass through checkpoint, build/test and preview stages before you approve publishing.

Does 20Flow own my code?

No. The GitHub repository remains in the customer's account, with access scoped to the repository the customer connects.

Can I use my own API keys?

The planned BYOK mode lets customers use their own provider keys while keeping the 20Flow workspace and Project Brain.
