Stop sharing mockups. Generate live, full-stack prototypes.

Product, support, and engineering teams use Flex to turn feature requests into live, working previews — complete with backends and databases, not just UI mockups. Plug it into your workflow via our API, webhooks, or native integrations.

Every team ships faster

Whether you're building prototypes, fixing bugs, or resolving customer issues — Flex gets you to a working solution faster.

💡

Product Teams

Ship without waiting

Prototype faster than you can schedule a meeting. Turn Slack discussions and analytics insights into working previews that engineering can review and merge.

PostHog/Mixpanel insight → preview
Communicate ideas with working code
Skip the spec, show the solution
⚡

Engineering Teams

Less context-switching

Bug reports become live fixes. Tickets become deployable branches. Review previews from product, merge what's ready, and stay focused on the complex work.

Linear ticket → working branch
Tiny features handled automatically
You stay in control of merges
🎯

Support Teams

Fixes, not just tickets

Turn customer issues into previews with proposed fixes. Close tickets faster with real solutions, not just escalations to engineering.

Why Flex

Why teams switch to Flex

From request to working preview

Turn product requests into real code changes, then inspect behavior in a disposable live environment before touching main branches.

Collaboration without handoff lag

Product can refine intent while engineering reviews implementation quality, all on the same source-of-truth codebase.

Context-rich browser workflows

Use the Chrome extension to capture user-facing context and attach it directly to agent tasks instead of writing long handoff docs.

Safer iteration loops

Experiment quickly in preview containers, then promote only validated changes to your production-ready delivery workflow.

Integrations

Plugs into how your team already works

Trigger previews from Slack, Linear, or any tool with webhooks. Your workflow stays the same — just faster.

Slack

Conversations to code

Turn any Slack thread into a live preview. Share a discussion, tag Flex, and watch your ideas become working prototypes in minutes.

Trigger agents from threads
Preview links posted automatically
Status updates in-channel

Linear

Tickets to prototypes

Link a Linear ticket to automatically spin up a preview. Add context in the description, and Flex handles the rest.

One-click preview from issues
Sync ticket context to agent
Auto-link previews to tickets

How it works

Three steps to faster shipping

  1. 1

    React to a request

    Add a 🚀 emoji in Slack, trigger from Linear, or describe what you need. Anyone can start.

    No code required
  2. 2

    Flex spins up your stack

    A full environment boots in your real codebase — backends, databases, everything. Not a sandbox.

    Real repo, real environment
  3. 3

    Review and merge

    Stakeholders see the working preview. Engineering reviews the code. Merge what's ready.

    Engineering stays in control
Why it works

Not just frontend code

Unlike tools that only generate React components, Flex runs your entire stack — whatever your backend, databases, APIs — in isolated containers. That's why product teams can ship real features, not just UI mockups.

Stop waiting for engineering sprints. Start shipping.

Flex gives every team the power to turn ideas into working features — with real backends, not just UI mockups.

FAQ

Frequently asked questions

What makes Flex different from a chatbot coding assistant?

Flex executes agent tasks in repository-aware workflows and spins up live preview environments, so teams can evaluate real behavior before merge.

Can product managers and designers use it too?

Yes. Flex is built for cross-functional workflows where product shapes intent and engineering governs final implementation quality.

How does the Chrome extension fit into the flow?

The extension captures in-browser context and sends it directly into agent tasks, reducing context loss between discovery and implementation.

Can I trigger previews from Slack or Linear?

Yes! Flex integrates directly with Slack and Linear. Tag Flex in a Slack thread or link a Linear ticket, and we'll spin up a preview automatically. We also support webhooks and a REST API for custom integrations with tools like GitHub, GitLab, Jira, and Notion.

Will this work with our current delivery process?

Yes. Flex is designed to plug into existing review and deployment practices so teams can increase throughput without sacrificing control.
