The verdict

If what you actually want is a working app that's already hosted, has a database, and is something you can keep building on for months, Replit Agent is the better daily driver. Its Core plan now ships full Agent access at a lower price than it did a year ago, and the workspace doubles as a real IDE when you need to pop the hood. If you want the fastest possible path from one prompt to a live URL in a browser tab, especially for a marketing site, a demo, or a single-page React app, Bolt.new is still hard to beat, and its free tier is genuinely usable. Either tool will get a non-trivial app built in an afternoon. The choice is mostly about what you do with it on day two, and whether you'd rather pay against effort-based credits or a token meter.

Replit Agent and Bolt.new keep ending up on the same shortlist for the same reader: someone who wants to describe an app and have it built, in the browser, without setting up a local stack. They've converged on roughly the same product surface (prompt-to-app generation, a built-in editor, one-click deployment, integrations with Supabase and Stripe) and on roughly the same starting price. The interesting questions are no longer "which one can generate a React app" but "which one survives the second prompt, the third bug, and the first month's invoice."

We ran both tools for two weeks against the same three briefs: a marketing site with a contact form, a small SaaS dashboard with auth and a Postgres table, and an internal CRUD tool with a CSV import. We graded four rounds: how well each one took the first prompt to a working app, how each handled iteration and bug-fixing once the codebase grew, how each one fit into a real deployment workflow with a database and a custom domain, and what each one actually cost after two weeks of normal building.

Round by round

First-prompt build
WinnerBolt.new

How we testedWe gave each tool the same three opening prompts (a marketing site, a SaaS dashboard skeleton, and a CRUD admin tool) and graded whether the first build ran without errors, how long it took, and how close the result was to the brief before any follow-up prompts.

Bolt was faster to a running preview on all three briefs, and the gap was widest on the marketing site. That tracks with how the two tools are built: Bolt runs the project in StackBlitz WebContainers in the browser, so nothing has to be provisioned between the prompt and a live preview. Reviewers who use both report the same pattern. Bolt is faster for quick prototypes and has a simpler interface, while Replit Agent gives you a more complete development environment with hosting, deployment, and a real IDE. Replit Agent's first builds were closer to a real project structure (it scaffolded a deployable app with a database wired up), but it took longer to get there, and the preview lag was noticeably worse on a free workspace.

Iteration and bug-fixing
WinnerReplit Agent

How we testedOnce each app was running, we ran the same six follow-up prompts on each tool: two feature additions, two bug fixes against a failing test, a refactor, and a 'change the auth provider' request. We graded how many prompts it took to converge, whether the agent broke unrelated code, and how often we had to hand-edit the files.

Once the codebase grew past a few files, Replit Agent held context better and broke fewer unrelated things. Replit's own documentation describes the modes that drive this: Agent runs with Economy or Power modes for autonomous work and Plan Mode for brainstorming, with Pro adding a Turbo Mode that's roughly 2x faster on the same models. Bolt's iteration story is improving. The team ships frequently, and the product in early 2026 is meaningfully better than the 2024 launch on context management, error handling, and code quality. But on the harder iterations, Bolt still tended to rewrite files we hadn't asked it to touch, and complex projects burn through tokens fast enough that fixing a stubborn bug can quietly cost more than the feature it broke.

Deployment, database, and ecosystem fit
WinnerReplit Agent

How we testedWe deployed each app to a custom domain, attached a real database, and connected it to GitHub. We graded what was included out of the box, what required leaving the tool, and how cleanly each one handed off to a real engineering workflow.

Replit is, end to end, more of a platform than a generator. Core includes PostgreSQL, custom domains, autoscale or reserved-VM deployments, and a real IDE if you want to drop into the code. Bolt has closed a lot of the gap with Bolt Cloud. Current docs describe Bolt Cloud databases, hosting, custom-domain support for Pro users, JavaScript-based backend support, and integrations with GitHub, Figma, Stripe, and Supabase, which makes Bolt a real app-builder option rather than just a sandbox. The catch is the surface it covers: Bolt focuses on JavaScript-based web technologies, supports Node.js for backend work, and does not support PHP or Python backends. For a Node front-end with a Supabase backend, that's fine. For anything else, Replit's broader language support and full IDE start to matter.

Price and billing predictability
WinnerBolt.new

How we testedWe tracked the actual two-week bill on each tool on the entry paid plan, then modeled a month of typical usage (one active project, daily prompts, a small always-on deployment) against current published pricing for both.

Both tools landed in the same neighborhood on sticker price, but Bolt's free tier and Pro plan are easier to predict. Bolt is free with 1M tokens per month and a 300K daily cap, then Pro at $25/month with 10M tokens, Teams at $30 per member per month, and a custom Enterprise tier; unused tokens roll over for one additional month on paid plans. Replit's pricing overhaul earlier this year dropped Core from $25 to $20/month and added up to 5 collaborators, then replaced the old Teams plan with a flat $100/month Pro plan for up to 15 builders. The complication on Replit is what the credits cover: Core's $25/month in credits is a shared pool covering Agent requests, app hosting, database compute, storage, and data transfer, and once it's depleted, overage charges accumulate with no default spending cap. Bolt's token meter can also surprise you on a complex build, but in two weeks of normal use we found Bolt's bill easier to forecast.

Replit Agent and Bolt.new are the two tools that keep coming up when someone says “I just want to describe an app and have it built.” They look more alike than they used to. They are not the same product.

Where Bolt.new wins

Bolt is the fastest way we’ve found to get from a prompt to a live URL in a browser tab. The moat is StackBlitz WebContainers, which let the development environment run in the browser instead of requiring a local Node install. That matters for schools, locked-down laptops, demos, and “I just need to try this now” workflows. The free tier is genuinely usable for a small project, and the Pro plan’s $25/month is easy to defend if a single afternoon of prompts replaces a freelance invoice.

The price is also the trap. Token usage varies wildly depending on what you’re building. A simple landing page is one thing, but once you start adding user permissions, authentication, data management, interface pages, debugging, and all the other infrastructure to make an app actually work, token usage really starts clocking overtime. If you’re iterating heavily on a complex feature, expect to burn through the Pro plan’s 10M monthly tokens faster than the sticker price implies.

Two narrower points worth knowing. First, the stack is opinionated: current supported-technology docs say Bolt focuses on JavaScript-based web technologies, supports Node.js for backend work, and does not support PHP or Python backends. Second, you’re not locked in. You can download your project as a zip, open it in StackBlitz, or push it to GitHub and keep working in editors like Cursor or VS Code, and this portability is one of Bolt’s strongest points.

Where Replit Agent wins

Replit’s advantage is what happens after the first prompt. A week in, you have an actual project: a real IDE, a Postgres database, custom-domain deployments, and an Agent that can plan, build, and iterate on the same workspace. Core membership gives you access to premium tools that take you from idea to app, including Agent for chatting through builds and debugging, full and lite build modes, a Design Canvas, a Visual Editor, all artifact types, and Plan Mode for brainstorming and planning work with Agent without editing code.

The pricing also looks better than it did six months ago. Core dropped from $25/month to $20/month, and existing Core subscribers will be charged the new price at their next renewal after Feb 25, 2026, with no action required. The same overhaul retired the old Teams plan: launched in February 2026, the Pro plan replaces the old Teams plan at $100/month for up to 15 builders, with tiered credit discounts, priority support, and credit rollover, including a flat $100/month fee with no per-seat pricing.

The honest caveat is that the subscription isn’t the whole bill. Your monthly credits aren’t dedicated to AI usage. They’re a shared pool covering Agent requests, app hosting, database compute, storage, and data transfer, and a developer who deploys a moderately active app while building new features can exhaust their Core allocation halfway through the month, after which any subsequent action is billed directly to your payment method without prior notice. If you build heavily, plan for that. If you’re a casual user shipping one small project, Core’s $20/month is more than enough.

Who should pick which

Pick Bolt.new if you want the fastest path from a prompt to a running preview, your project is JavaScript-native, and you mostly need a marketing site, a single-page app, or an MVP you can hand off to a developer later. Pick Replit Agent if you want a real workspace you can grow into (a database, deployments, a code view you can actually use, and language support beyond Node) and you’d rather pay a flat $20/month with usage credits than meter tokens.

One thing worth watching: both products are revising their pricing aggressively. Replit overhauled its plans in February, Bolt’s token model is still settling, and we’d re-check the bill on a real project before committing a team. For a solo build this quarter, either tool is a reasonable answer to a question that didn’t really have one two years ago.
