From request to working preview
Turn product requests into real code changes, then inspect behavior in a disposable live environment before touching main branches.
Give everyone on your team an AI software developer.
Flex helps teammates build internal tools, prototype product changes, and safely ship improvements to real production apps. Every run happens in your codebase, with live previews hosted on your secure infrastructure.
- Teammate → App
- No code required
- Real Product
- Not static pages
- Your secure infrastructure
- Host securely
What should your AI developer build first?
Flex is for real software work, not static mockups: internal apps your team can use, safe changes to production products, and rapid prototypes against the app you already have.
Internal apps & dashboards
Ship useful tools
Give operators, PMs, RevOps, support leads, success teams, and team leads a way to build real workflows and share them with teammates.
Data views, forms, workflows, and reports
Hosted on your secure infrastructure
Shareable with the teammates who need it
Production product changes
Safe changes to real apps
Let teammates request changes to the real product while engineering keeps review gates, code quality, and merge control.
Real repo, isolated preview environment
Engineering reviews before merge
Hosted on your secure infrastructure
Rapid product prototypes
Validate before you commit
Explore changes to the product you already have. Share a live preview, learn from it, then decide what deserves engineering time.
Turn a product idea into a live flow
Test against the existing app
Share previews before roadmap commitment
Why
Flex
Why teams switch to Flex
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.
Host on your secure infrastructure
Run agent work and previews on infrastructure your team controls, then promote only validated changes to your 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

Flex
How it
works
Three steps to faster shipping
-
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
Flex spins up your stack
A full environment boots in your real codebase — backends, databases, everything. Not a sandbox.
Real repo, real environment -
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 static pages
Unlike tools that only generate React components, Flex runs your entire stack — whatever your backend, databases, APIs — in isolated containers on your secure infrastructure. That's why teammates can build useful apps, prototypes, and product changes instead of static 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 non-technical teammates use it too?
Yes. Flex is built for teammates who need useful software but do not want to write code. Engineering still 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.
