Replit, the app-building platform, has given its coding agent, Replit Agent, two abilities that have nothing to do with writing code: purchasing supplies on behalf of a business, and creating and running Google Ads campaigns directly inside Replit. Both features launched on November 12.
Replit's reasoning is simple. More and more people are using its Agent to build small businesses that actually take payments, and once the product is built, they want the Agent to keep going with the chores of sourcing supplies and winning customers. One figure the company offers: since May, the number of founders connecting their Replit-built businesses to Stripe for payments has grown to nine times what it was.
Purchasing: it must stop before checkout
The purchasing feature is called Agentic Commerce, with payments handled by Stripe's Link and Visa. The official example prompt reads: find 50 shipping boxes that fit this product, for no more than $75 including shipping.
The Agent draws on what it knows about the business to find the goods. A browser sub-agent opens the merchant's site, picks the specifications, adds items to the cart and walks through to the checkout page, then hands the order details back. The card is charged only after the store owner confirms the final amount. The browser is provided by Browserbase, so Replit does not need a separate integration with each store; when a site requires a login, the user can take over the browser, sign in and hand it back to the Agent.
The constraints around payment are stated firmly:
“approval checks are enforced in code, not left to the model.”
During payment, shell access and ordinary browsing are switched off, browser sessions are isolated from one another, and Link restricts each transaction to the single order the user approved. Replit says the Agent will “never get an uncapped license to spend.” The blog post does not mention any per-transaction or monthly spending limits.
The feature is available to Core and Pro users, supports one-time purchases only, and starts in the US.
Advertising: people set the budget
The other feature is Agentic Ads with Google, covering Search, YouTube, Display, Discover and other channels. Users can connect an existing Google Ads account or ask the Agent to open a new one. Replit analyzes the content of the website or app, drafts ad copy, generates images and recommends a daily budget. It can also add conversion tracking, so performance is measured by sign-ups and sales rather than clicks alone.
Campaign goals, audience targeting, budget and landing pages are decided by the user, who reviews the creative before it goes live. The feature is for Pro users only and is available worldwide starting the same day.
Running the numbers on the official case studies
The blog post includes stories from two customers. All figures are self-reported by the customers, and Replit has not provided third-party verification.
One founder of a bid-proposal software company says in the example that he is willing to spend “$40 a day for 30 days,” a total budget of $1,200. Another customer, Austin Eckman, runs Crafting Table; Replit says he earned $170,000 in 30 days with a return on ad spend of roughly 4x. Working backward from 4x, ad spend over those 30 days comes to somewhere around $40,000, or about $1,400 a day, 35 times the budget in the first example.
A third customer, Jon Cheney, says an outside team quoted him $105,000 for his app, while he built it on Replit over a weekend for under $400, and the app earned six figures in its first six weeks live.
These cases show the ceiling, not the average. Part of the cost of advertising hides in the learning period, and conversions on a new account are often unstable for the first few weeks. The blog post gives no data on whether the budget the Agent recommends can last through that stretch.
How this differs from other shopping agents
This year, many AI model companies have been building agents that place orders for people, mostly aimed at individual consumers buying clothes or booking restaurants. Replit has chosen two narrower scenarios, business procurement and marketing, for users who are small-business owners that have already built a business on its platform. The payment method, checkout approval and spending caps are all in the store owner's hands.
Stripe recently announced it is acquiring OpenRouter, and now it has put the Link wallet into Replit's agents as well, which puts payment companies ever closer to the front of agent transactions. Replit has not yet given a timeline for bringing purchasing outside the US.
