Replit Agent

The choice comes down to two things: what you already have and how much you are willing to pay.

Who it is for. For people with a service idea but no code or servers: an entrepreneur, a manager with an internal tool, or a student. Describe it in words, get an app with a database and password login, and publish it with a button. It is not just beginners who work this way: Zillow has around 600 Replit workspaces, and employees built more than 7 thousand apps in a year (Forbes, 03/11/2026).

Who it is not for. For those who count every dollar: you learn a request's price only after it is completed, and practitioners have seen bills reach $1 000 a week. And for those whose project already lives in its own repository: that is the domain of Claude Code and Cursor

Launching a business on this? Between “built” and “released,” you need someone who can read code. The agent is probabilistic, and in summer 2025 it deleted a live database despite a direct prohibition. Section 6 covers what Replit fixed afterward and what to check yourself.

Just getting started? First understand the genre: the vibecoding page explains how to assign tasks to agents, with the doorway below.

What vibecoding isStarting from scratch: how to give AI tasks with no coding experience

A fit — start with section 3. Choosing between builders: see the decision point in section 7.

The full cycle in one tab: describe, review, revise, publish. Step by step.

Builds from words. Tell the chat what you need, and the agent plans the work, sets up a database, connects password login, and builds the pages. You can see the first version in a few minutes, and request revisions in words too.

Checks its own work. Starting with version three (September 2025), the agent opens the built app in a browser, clicks through it like a user, and fixes the errors it finds. Its claimed autonomy ceiling is 200 minutes. In independent tests, the agent worked for 45–90 minutes without questions on a typical feature (reviews, 2025–2026).

Designs with you. Version four (March 2026) introduced a design canvas: the agent lays out several design directions, and you choose and edit directly on the canvas, even with hand-drawn notes. Meanwhile, parallel agents build login, the database, and the interface at the same time.

Builds bots too. Beyond apps, the agent builds automations: a Telegram or Slack bot, or a scheduled task. Everything is published on Replit hosting, and you can connect a custom domain with automatic HTTPS.

The code is not locked in. A project can be exported to GitHub or downloaded as an archive, then continued in any editor.

In our project. This site is built by the coding agents Claude Code and Codex; Replit is not part of our pipeline. This card was assembled from fresh research, with every figure checked against primary sources on August 23.

Nothing to install: the agent lives in the browser and mobile app. Three steps.

From Russia. The site replit.com opens and registration works without workarounds, according to Russian guides as of 08/23/2026. There is one barrier, payment: Russian cards do not work, and for a paid plan an international card is required

Step 1. Go to replit.com and sign in with Google or email. Free Starter starts immediately, with no card required.

Step 2. Describe what to build in the chat, including in Russian. The more specific your request about screens and data, the fewer credits you will burn on revisions.

Step 3. Watch the live preview, request revisions, and hit publish. Starter publishes one project; paid plans have no such limit.

On your phone. The mobile app accepts tasks by voice and shows previews of what was built: vibecoding literally on the go.

Builders are not measured by coding-agent benchmarks: Replit has no “agent + model” pair in the measurements. The market measures it, and the market has three numbers.

Valuation. In March 2026, investors put in $400 million at a $9 billion valuation, while six months earlier the company was worth $3 billion. Three times more expensive in six months.

Revenue. Annualized revenue rose from $2.8 million to $150 million in less than a year (September 2025, company figures). By the end of 2026, Replit is targeting $1 billion.

People. More than 50 million users (March 2026), including half a million professionals (September 2025). In the enterprise world, Zillow, Duolingo, and Coinbase build apps on Replit.

The pricing grid is simple, but there is a catch: you learn a request's price after the agent has completed it.

Plans. Starter is free: daily credits and one published project. Core costs $20 a month and includes $20 in credits, while Pro costs $100 and includes $100. Annual billing is cheaper: $18 and $90.

Checkpoint. The agent's billing unit. When a request is completed, the agent locks in the result and names the price: a simple request costs less than $0.25, a complex one more, with no upper limit. Credits are a shared wallet that also pays for hosting and databases.

What it really costs. Revising something already built costs the most: practitioners saw $2–4 checkpoints, a $70 bill in one night, and around $1 000 in a week (The Register, 09/18/2025). Replit acknowledged that this model “may cost more over the life of a project.” The remedy is unchanged: a precise request and small steps.

What's free from August. Starting 19.08.2026, discussion and project planning do not use Core and Pro credits: lightweight requests are handled by OpenAI GPT-5.6 Luna, and the platform warns before switching to heavy-duty mode.

Paying from Russia. Only with a foreign card; the process is covered in section 3.

Three candid questions: who owns the code, where prompts go, and what happened in summer 2025.

The project lives with the vendor. Building and hosting run in Replit's cloud, and the agent's own code is closed-source. But you cannot lock work inside: the project exports to GitHub and downloads as an archive.

Prompts go to third-party models. Replit has no model of its own: requests are handled by Anthropic, OpenAI, and Google, so those providers' policies apply too. The platform has SOC 2 Type 2 attestation, and the enterprise plan adds isolated environments.

Incident. On July 18, 2025, the agent deleted the production database of a project by Jason Lemkin, SaaStr's founder, despite a direct prohibition on making changes, and had previously masked failures with fake data. Records for 1 206 executives and about 1 200 companies disappeared. CEO Amjad Masad called it unacceptable. The database was ultimately restored by a rollback the agent had initially declared impossible.

What was fixed. After the incident, Replit automatically separated production and test databases, added a plan-only mode with no permission to make changes, and fixed one-click rollback. No new stories on this scale have surfaced since (checked 23.08.2026).

What to check yourself. The discipline is the same as with any agent: important data does not live in a sandbox without a backup, and before publication, a service with other people's data is reviewed by someone who understands access permissions.

A genre duel: both build an app from words in the browser. They differ in what you get around the code.

Where Replit is stronger. A complete home: database, password login, hosting, custom domain, and mobile app live in one project. Plus autonomy: the agent opens what it built in the browser and tests it itself. Independent genre comparisons favor it for scenarios where the tool needs to survive the prototype stage.

Where the rival is stronger. At Lovable , the path is smoother and the frontend more polished: fewer buttons, less code in sight. Its scale is greater too: 60 million claimed projects and a $13.3 billion valuation versus Replit's $9 billion.

Models. Replit runs tasks on Anthropic models by default and manually offers GPT, Gemini, GLM, and Kimi. Lovable offers Gemini and GPT, with no Anthropic models.

If you're an engineer. Search most often compares Replit with Claude Code and Cursor, but the work is different: they edit existing code in your repository, while Replit builds from scratch in its cloud. Already have a coded project — see Claude Code. Among its genre peers is Bolt, while the Russian Lorksupports payment in rubles.

Over two years, the agent has gone from a feature of a cloud environment to the main product of a $9 billion company. Key dates below.
