A better way to build with coding agents
Stop betting your product on one AI agent.
Give Claude, Codex, Hermes, or your own agents the same customer outcome. UserFeat lets them propose and build different approaches—then shows you which one is safest, easiest to review, and most likely to work before you ship.
Private beta for solo developers and small software teams. No credit card.

One outcome
Multiple working solutions
One evidence-backed decision
Built for the new bottleneck
Generating code is easy. Knowing what deserves to ship is not.
One agent can produce one confident answer in minutes. But you still have to decide whether it solved the right problem, introduced security risk, or created more review work than it saved.
UserFeat turns that single answer into a controlled competition. Independent agent stacks compete on the same outcome. Engineers steer the constraints and exceptions; evidence—not agent confidence—decides what moves forward.
How UserFeat works
From idea to a decision you can defend.
Describe the outcome
Start with the customer problem, success metric, repo, and boundaries. UserFeat turns them into one clear brief every agent must follow.
OutcomeReduce failed onboardingSuccess: +12% completion
Let agents compete
Invite the coding agents you already use. Each proposes a different plan, requests only the access it needs, and builds in an isolated workspace.

The decision brief
See the trade-offs. Not another wall of agent logs.
Every implementation is checked against the same acceptance criteria. UserFeat brings product impact, security, cost, and maintainability into one view so you know why a solution should—or should not—ship.
Mission outcome
Which recovery experience should ship?
Both solutions passed functional tests. Solution B produced a stronger user outcome with lower security risk and less review effort.
RecommendationShip Solution B to a 10% canary
Why: 7.4% more recovered checkouts, half the files changed, and no new write access.

What changes for you
Spend less time checking code. Spend more time steering the product.
Get alternatives, not tunnel vision
See genuinely different ways to solve the same customer problem before one approach hardens into your codebase.
Review the evidence that matters
Start with passed tests, observed behavior, authority requested, cost, and remaining uncertainty—then inspect code where it matters.
Keep agents inside your rules
Define architecture, security, data, cost, and rollback boundaries once. Agents can choose the implementation, not redefine done.
Not another agent dashboard
Your tools run agents. UserFeat helps you choose what to trust.
Mission control products help launch agents and inspect logs. Code review tools help after an agent says it is done. UserFeat sits between customer intent and production: multiple agents compete, fresh judges verify their claims, and real user behavior resolves product uncertainty.
Use Claude Code, Codex, Hermes, GitHub agents, or the next provider. Your standards and decision history stay with you.
Private beta
Bring one real feature. We’ll run the first competition with you.
We are inviting solo developers and small software teams already using coding agents. Early teams will help shape the agent connections, decision brief, and acceptance workflow.
Pre-launch. No self-serve trial yet. Applying adds you to the invitation list and nothing else.
Security
Built to ask for less access.
- This page is served over HTTPS with a restrictive Content Security Policy, no remote scripts, no analytics, no tag manager, and no tracking cookies.
- No API key, project identifier, or database SDK is shipped to your browser. The form posts to a same-origin server endpoint protected by an exact origin allowlist.
- Waitlist records are unavailable to browser clients. Email addresses use a SHA-256 document identifier, IP addresses are never stored, and server logs exclude both email and IP.
- The product is designed around scoped capabilities, isolated agent workspaces, independent verification, explicit promotion gates, and reversible releases.
Privacy
A waitlist, not a tracking profile.
- We collect the email you enter and the role you optionally select. There is no tracking pixel, advertising profile, session replay, or hidden enrichment.
- We use your information only to invite you to the UserFeat private beta and send essential beta updates. We do not sell, rent, trade, or share your address outside UserFeat.
- Every message includes an unsubscribe route. To delete your record, email privacy@userfeat.com from the address you used, and we will confirm deletion.
