Replit vs Bolt: Which AI Builder Should You Use?

Replit and Bolt can both take a prompt and produce a running, database-backed application, but Replit is built around a full cloud development environment with four separate deployment types, while Bolt is a narrower builder that publishes straight to one default host. Replit's own Agent documentation describes an Agent that "sets up your project, creates applications, checks its work, and fixes problems along the way," inside a workspace that also does version control, a SQL database, and a choice of Autoscale, Static, Reserved VM, or Scheduled hosting. Bolt keeps that surface smaller: one hosting default, an automatic database, and a more direct edit-and-publish loop. Here's what each vendor's own pages say.

What does each one actually build?

Replit's Agent documentation describes it as a general-purpose builder, not one scoped to websites: "Replit Agent turns your ideas into apps, designs, slides, and more, all from plain language. No coding required," building "Web apps, mobile apps, data dashboards, and AI-powered tools" (Replit Docs, "Agent", checked September 2026). Agent doesn't just answer questions — it "takes action: it sets up your project, creates applications, checks its work, and fixes problems along the way" (same source).

Bolt's own documentation describes itself as "an AI-powered builder for websites, web apps, and mobile apps" (Bolt, "Intro to Bolt", checked September 2026), with examples ranging from landing pages and e-commerce shops to CRMs, SaaS platforms, and mobile games. For mobile, the same page says "To build mobile apps, you use the Expo integration." Both build real web and mobile apps; the difference shows up once you get past generation, in how each one deploys and hosts what it builds.

How does each one deploy and host a published project?

Replit documents four distinct deployment types, each built for a different job. Its docs describe Autoscale as the general-purpose default: "Autoscale Deployments run on servers that scale up and down with your app's traffic." Static Deployments are narrower and explicitly incompatible with Agent-built apps: they host your app's HTML, CSS, and JavaScript files with no backend server, and "Static Deployments are not compatible with Replit Apps created using Agent." Reserved VM trades elasticity for a fixed, always-on machine: "Reserved VM Deployments run your app on a dedicated virtual machine that never sleeps." And Scheduled Deployments exist purely for recurring jobs: "Scheduled Deployments run a command on a schedule in your app's environment, then stop until the next run" (Replit Docs, "Deployment types", checked September 2026). For a published app, "Replit provides a free subdomain in the format <your-live-app-subdomain-name>.replit.app" (Replit Docs, "Custom domains", checked September 2026) — and that custom-domains page covers buying a domain on Replit or connecting one you already own.

Bolt hosts everything on one default, with no deployment-type choice to make. "When you publish a project with Bolt, it automatically goes live on a free bolt.host domain" (Bolt, "Domains", checked September 2026). A custom domain requires a paid plan and doesn't survive a downgrade: "Custom domains are only available on paid plans, so you'll need to upgrade from Free to any paid tier to use one," and "If you downgrade to the Free plan, you'll no longer be able to publish to your custom domain" (same source). There's no equivalent to Replit's Reserved-VM-for-always-on or Static-for-files-only distinction documented in Bolt's hosting pages — one project type, one hosting path.

How does each one handle GitHub and code ownership?

Both support bringing an existing repository in, and pushing code back out — but through different mechanisms. Replit documents importing "a GitHub repository into Replit to run, test, and publish faster" (Replit Docs, "Import from a provider", checked September 2026), via a guided flow or a direct URL. Getting code back out is a separate, documented feature: Replit's Git pane lets you link your repository to a hosted or self-hosted Git provider and push your commits to that remote with a single click (checked September 2026) — a real two-way path between an existing repo and a Replit project.

Bolt documents the same shape from its own side: "You can bring an existing GitHub project into Bolt, or start building in Bolt and create a new GitHub repository for your project" (Bolt, "GitHub for version control", checked September 2026), though "Bolt currently doesn't support merging branches in-app. You need to merge branches in GitHub" (same source). Bolt also documents a Git-free path: "You can download your project as a zip file to work on it outside of Bolt, using your own code editor" (Bolt, "Manage your projects", checked September 2026).

What database does each one provision?

Replit documents a "fully-managed SQL database" with "20GB of free storage for every Replit App" (Replit Docs, "Database", checked September 2026), built into the same workspace as the code editor and Agent. Bolt's default is automatic and provider-flexible instead: "Bolt creates a database automatically if your project needs one, or if you explicitly ask Bolt to create a database or a database-related feature," with "If you prefer to use Supabase when creating a new project, you can select it during setup" (Bolt, "Database", checked September 2026) — a provider choice Replit's own database docs don't describe for its built-in SQL database.

How does each one's pricing actually work?

Replit's pricing page currently defaults to its Yearly view, showing Core at $18/month billed annually and Pro at $90/month billed annually (Replit, pricing page, checked September 2026) — the struck-through $20 and $100 beside them are reference prices, not separate plans. Each plan includes monthly credits ($20 for Core, starting at $100 for Pro), and the page's FAQ says "Credits cover all your usage across Replit." They pay for building with Agent, publishing, and database operations, with usage beyond your monthly credits billed pay-as-you-go under what Replit calls Effort-Based Pricing (same source).

Bolt's pricing page defaults to Monthly, listing Free at $0, Pro at $25/month, Teams at $30/month per member, and a custom Enterprise tier (Bolt, pricing page, checked September 2026). Bolt prices by a token allowance per plan rather than Replit's credit-plus-overage model — Free has a 300K daily token limit and 1M tokens a month, while Pro removes the daily cap and starts at 10M tokens a month (same source).

Capability matrix

Who is each one not for?

Replit is not the fit if you want one simple hosting default and don't need to choose between deployment types — four options is more surface area than a small marketing-site project usually needs.

Bolt is not the fit if you specifically need an always-on Reserved-VM-style host or a scheduled recurring job as a first-class deployment type — Bolt's hosting documentation doesn't describe those categories.

Is Figment a fit for either kind of project?

No. Figment publishes a Figma design as a live website through its Figma plugin; it doesn't run an AI coding agent, provision a database, or offer deployment-type choices, and its AI editor, public now, edits a separate static copy of an existing site rather than building an app. Neither Replit nor Bolt's job — an AI-built, database-backed application with real deployment infrastructure behind it — is what Figment does. Our Replit pricing and Lovable vs Bolt guides cover each vendor's numbers and Bolt's mechanics against a third builder in more depth than repeated here.

Which should I actually pick?

• Pick Replit if you want a full cloud development environment with a choice of deployment type per project — an always-on Reserved VM, a cheap Static host, or a Scheduled job — plus one-click GitHub push built into the workspace.
• Pick Bolt if you want a simpler, single default hosting path with a more direct edit-and-publish loop, and you're comfortable with a per-plan token allowance instead of a credit-plus-overage pricing model.
• Check both vendors' current pricing pages before committing — Replit's default billing view and Bolt's token allowances are each set on pages that update independently of this guide.

Bottom line: Replit is the broader tool — a cloud IDE, four deployment types, and a built-in database, all wrapped around the same Agent that writes your code. Bolt is narrower and more direct: one hosting default, an automatic database with a Supabase option, and a shorter path from prompt to published app. Pick based on whether you want that extra deployment and workspace surface, or a smaller, faster loop.
