Replit launched Agent 3 in September 2025 and it changed the product meaningfully. This is not a minor model upgrade — Agent 3 operates with significantly more autonomy than previous versions, handles full tasks from start to finish without requiring constant prompting, and introduced real-browser testing that catches visual bugs rather than just logic errors. The existing narrative that Replit “lags behind Lovable” needs updating.

For non-technical founders, the appeal of the Replit app is that it bundles everything vibe coding needs — AI builder, editor, database, and hosting — into one place you can use from a browser or the mobile app. If you’re evaluating Replit for vibe coding specifically, here’s how it actually performs.

New in May 2026: Free imports from Lovable, Base44, and V0 — plus the App Store fight continues

Replit shipped two notable updates on May 15. First: you can now import your project from Lovable, Base44, or V0 into Replit for free. The promo is a direct poaching play — after importing, Replit Agent builds a free mobile app from your project and submits it to the App Store. For founders who started on a visual builder and hit its ceiling, this is an easier migration path than rebuilding from scratch.

Second: Replit’s iOS app shipped its first update in four months, breaking a streak that Apple’s review process had effectively frozen since January. The App Store fight between Apple and vibe coding platforms — triggered by section 2.5.2 of the App Review Guidelines, which restricts apps from executing code that changes their own functionality — shows signs of softening. Replit’s ability to push this update suggests some negotiated accommodation, though neither Apple nor Replit has publicly confirmed terms. Masad’s “we’ll take it to court” posture from early May appears to have produced results without a courtroom.

The practical implication for builders using Replit’s mobile output path: the mobile-first feature that made Agent 3 a strong option for app builders is no longer stuck in App Store limbo.

New in May 2026: Replit plants the independence flag while Cursor flirts with SpaceX

At TechCrunch’s StrictlyVC event on May 1, Replit CEO Amjad Masad answered the question of the moment — would Replit also sell, given that rival Cursor is reportedly weighing a $60B acquisition by SpaceX — with a clear “we’re going to try to stay independent.” The supporting numbers are the more interesting part of the interview: Replit went from $2.8M of revenue in all of 2024 to a self-described billion-dollar annual run rate, has been gross-margin positive for over a year, and is reporting net revenue retention “as high as 300%.” Masad explicitly contrasted Replit’s economics with Cursor’s reported negative-23% gross margins, framing independence as the path Replit can afford and Cursor structurally can’t.

For non-technical founders making a 12-month tool bet, the practical takeaway is the one Masad is selling: Replit looks substantially more likely to still exist as Replit a year from now than Cursor does. The other thread worth tracking is the App Store fight — Masad publicly called Apple’s review-process explanations “outright lies” and said he’s prepared to take the dispute to court. That’s a useful signal for builders relying on Replit’s mobile-app-publishing path, which has been one of the platform’s competitive moats since Agent 3 added native mobile output.

New in April–May 2026: Security Agent and Workspace Security Center 2.0

Replit shipped two security features over the past four weeks that directly answer the “vibe-coded apps are a security debt problem” narrative dominating coverage of the category. On April 21, Replit launched Security Agent, a pre-publish reviewer that builds a threat model of your app, maps your routes and data flows, runs Semgrep and HoundDog.ai under the hood, and then uses an LLM to decide which findings are actually exploitable in context — rather than dumping every theoretical false-positive on you. A full deep audit takes around 15 minutes on larger projects. It’s available to all paid builders, which matters: this is the first time a vibe coding platform has put a real security-review pass directly in the publish flow rather than treating it as an add-on.

On May 8, Replit followed with Workspace Security Center 2.0 — the org-level view on top of Security Agent. It surfaces your highest-risk projects across a Replit workspace, lets you filter by severity, publish status, visibility, and owner, kick off Agent remediation tasks in bulk, unpublish high-exposure projects, and download SBOMs. For a solo founder this is overkill; for a team running 10+ Replit projects (the realistic Teams-plan scenario), it’s the thing that makes “we ship on Replit” defensible to anyone asking about security posture.

The combined story matters for two reasons. First, Replit is the only consumer-facing vibe coding platform with an integrated pre-publish security review live and in production right now — Lovable’s Security Scan is comparable in scope but newer and Supabase-coupled, and Cursor’s Security Reviewer is still in beta and Teams/Enterprise-only. Second, it’s a credible response to the Lovable BOLA exposure, the Base44 critical vulnerability, and the broader vibe-coded apps data exposure story that’s been the dominant narrative against this category all year. If you’re choosing where to build something that handles user data, this materially strengthens the Replit case. Sources: Replit blog — Meet Replit Security Agent, Replit blog — Security Center 2.0.

New in April 2026: Agent 3’s pricing problem (and how to manage it)

The second week of April surfaced a real, well-documented complaint about Agent 3 that’s worth flagging up top: users are burning through credits much faster than they expected. InfoWorld and Replit’s own community forum document users spending $1,000 in a single week against typical monthly bills of $180–$200. One user reported a single prompt costing $20 because Agent 3 spun up subagents to redesign their UI without being asked. Replit’s “10x more autonomous” pitch is also why it can run up an unexpectedly large bill — autonomy and predictability are different axes, and the move to effort-based pricing (compute consumed, not checkpoints created) compounds the surprise.

The practical advice for non-technical founders today: set a hard monthly spending cap before you start building, treat the first week as exploratory rather than production, and watch for Agent 3 deciding to refactor things you didn’t ask it to touch. Replit has not yet shipped a way to pin to Agent 2 the way OpenAI lets you choose between models, which is the most-requested fix in the community thread. We’re still recommending Replit for ambitious full-stack builds — the underlying capability gap over Lovable and Bolt on complex projects hasn’t closed — but go in with a budget and a plan to babysit the early sessions. Sources: InfoWorld, Replit Community: Agent 3 is extremely expensive.

What Agent 3 actually changed

The biggest shift is autonomy. Earlier versions of Replit Agent needed regular check-ins. You’d describe something, it would take a few steps, pause, and ask you to confirm or redirect. Agent 3 is described by Replit as “10x more autonomous” — it takes complex tasks end-to-end and only surfaces genuine decision points rather than procedural interruptions.

The real-browser testing is the other standout. Most AI builders generate code and let you figure out whether it looks right. Replit Agent 3 tests the running app in an actual browser during the build process, catching layout issues and interaction bugs before you even see the result. For non-technical founders who can’t read code to spot errors, this matters.

Building agents inside your app

Something Lovable and Bolt don’t offer: Replit Agent 3 can generate other agents and automations within the app you’re building. If you’re building a product that needs its own AI-powered workflows — automated email responders, data processing agents, background tasks — you can describe them to Replit and it builds them as part of your app. This positions Replit at a genuinely different level of ambition than the simpler builders.

Mobile native apps

In early 2026, Replit added mobile native app capability via Expo. If you need a real iOS or Android app — not a web app that opens in a phone browser, but something that runs natively on the device — Replit now handles this. Neither Lovable nor Bolt currently offer this path.

The IDE is still there, and it still matters

Replit started as a browser-based coding environment in 2016, and that foundation remains. You can drop into code, edit directly, and interact with the environment at a low level if needed. For founders who want to understand what’s being built — or who have a technical co-founder reviewing the output — this is more useful than the pure natural-language-only tools.

Integrated one-click deployment has always been Replit’s quiet advantage. No Vercel, no GitHub Actions, no DNS configuration. When your app is ready, it ships. That remains true and is even more relevant as Agent 3 handles more ambitious builds.

What Lovable and Bolt still do better

For a simple web app or SaaS prototype with a clean UI, Lovable is still faster and the output is more immediately polished. Bolt is competitive at this level too, especially with Bolt Cloud. If you have a narrow, well-defined spec and want the quickest path from idea to shareable link, Lovable remains the reference standard.

Replit’s interface also reflects its heritage as a developer tool. It’s more complex than Lovable’s clean editor, and that can be disorienting if you’re expecting a simple prompt-and-preview experience.

Pricing

The free tier exists but is limited. The Core plan at $25/month is the working tier for serious use. Compute and AI credits are consumed by Agent tasks, so complex builds can run through credits faster than simple ones.

Bottom line

Replit Agent 3 is a different product than what you might have heard about. If you’re building something that needs mobile native support, internal AI agents, or genuinely complex full-stack architecture, Replit is now the strongest AI-native tool for the job. It’s not the fastest path to a simple prototype — use Lovable for that — but for builders with more ambition than a basic app, Replit has outgrown its “beginner IDE” reputation. The April 2026 caveat: the autonomy that makes Agent 3 powerful is also what makes it expensive, so set a budget cap before your first build and treat the first session as a learning expense, not a production one.
