Preparing your workspace…

I want to enter a ticker and get a summary of the fundamentals. Give me a table and a chart of the share price plus the key ratios. Pull the data from Larkspur Markets and let me export the table as a CSV.

I'm hooked. For my whole design career I've had to borrow an engineer for even the smallest interactive idea. Having a builder sitting next to me all day is a genuinely different job.

Used Wrenly Builder to put together a symptom dashboard from a sample clinic export. Wanted to see how it handled 14 months of messy data — it produced a heat map I'd have spent a fortnight on.

Why haven't you built your own CRM with Wrenly Builder yet? Ours took an afternoon and two coffees, and it finally matches how our team actually sells.

What makes Wrenly different from other AI tools?

Build a working app and put it online the same day

Most tools stop at the front end or hand you a snippet to paste somewhere. Wrenly takes you all the way: a running application, hosted for you, with a link you can send to friends and customers in a couple of clicks.

No shuttling code between a chat window and an editor

Builder and Refiner work directly on the project files. You describe the change; it lands in the running app. Nothing to copy, nothing to reconcile by hand.

It reads the error before you do

When something breaks, Wrenly reads the stack trace, traces the failing path across files, and proposes a fix you can accept or refuse — with a plain-language note on what changed.

Editor, database, hosting and domains in one place

Storage, secrets, environments, custom domains and logs are already wired together, so a working prototype becomes a real product without a weekend of plumbing.

Built for real projects, not toy demos

Projects keep full version history, run on machines you can resize, and can be handed to a teammate at any point. Nothing is locked to a session.

Frequently asked questions

What is Wrenly Builder?

Wrenly Builder is an AI tool made for people building software. It works across the whole project — reading files, writing code, running the app and checking the result — so you can go from an idea to something that works without knowing every layer of the stack. Tell it what you want to make and it drafts the plan, builds it, and tells you when it is ready to look at.

How does Wrenly Builder work?

You describe the app in a sentence or two. Builder writes a short plan, sets up the project, installs what it needs, and works through the plan step by step while you watch. At any point you can interrupt, change direction, or hand the project to Refiner for smaller edits.

How much does Wrenly Builder cost?

Builder is included with Wrenly Core at $23 a month, which covers 1,240 build minutes and three always-on deployments. Heavier use is billed per build minute, and teams start at $37 per seat.

Is Builder an autonomous agent?

It works on its own between checkpoints but never past them. Builder pauses for confirmation before installing dependencies, touching data, or publishing, and every change is a reviewable step you can roll back.
