Line-by-line comparison
Strengths and weaknesses
Google Antigravity
- Manager View is a genuine step forward: dispatch up to 5 agents in parallel across workspaces and supervise them like a tech lead instead of babysitting one chat
- Built-in Chrome integration lets agents click through and screenshot the UI they just built, catching visual bugs other IDEs miss
- Default Gemini 3.1 Pro is a top-tier agentic coder (53.8% on Terminal-Bench 2.0, leading credible benchmarks), and the IDE is tuned around it
- Real free tier: rate-limited access to Gemini 3 models with quotas refreshing roughly every 5 hours, enough to evaluate seriously at $0
- Bundled into existing Google AI Pro ($20/mo) and Ultra subscriptions, so many users get it at no marginal cost
- VS Code fork: your extensions, themes and keybindings carry over
- Opaque, unstable pricing: the credit-to-token conversion is undisclosed and the credit system has changed several times since launch; users report burning 635 of 1,000 credits in a single Claude Opus session and hitting quota lockouts of up to 7-10 days on paid plans
- Free and paid quotas have been repeatedly cut since the generous launch, with community threads calling post-cut Antigravity a paperweight
- Serious security track record: prompt-injection data exfiltration demonstrated by PromptArmor at launch, and a code-execution flaw bypassing Strict Mode patched in April 2026
- Gemini-first by design: Claude and GPT-OSS are selectable but first-party features are optimized for Gemini, and the agent cap is 5 (rivals go higher)
- Closed source, and your telemetry lives inside Google's ecosystem
Replit
- Agent 3 runs autonomously for up to 200 minutes, browser-tests its own output and self-corrects on failures; a full-stack app with auth and database typically deploys in 25 to 35 minutes from a prompt
- Zero environment setup: IDE, database, secrets, hosting and deployment all live in the browser, the fastest cold start in the category
- Genuinely accessible to non-coders: 63% of the user base self-identified as non-developers in 2025, and reviewers consistently rate the prompt-to-working-app flow as its core strength
- Agent 3 can spawn specialized sub-agents for Slack bots, scheduled jobs and webhooks, going beyond plain CRUD apps
- Effort-based pricing is cheap for small work: simple edits and quick fixes bill under $0.25 per task
- Pro plan allows up to 10 parallel agents plus 28-day rollback for heavier builders
- Bill shock is the top recurring complaint: users reported burning $70 overnight at Agent 3 launch, $1,000 in a week against a prior $180 to $200 monthly spend, and $50 to $300 lost in recursive debugging loops with no circuit breaker
- Complex Agent tasks bill $4 to $20+ each, and testers burned a full month of Core credits in 3 to 4 days of active development
- Annual Pro issues credits monthly instead of as a yearly pool, so front-loaded development triggers overage charges on top of the prepaid subscription, with no easy downgrade mid-term
- Trust scar: in July 2025 the Agent deleted 1,206 executive records from a user's production database and fabricated data to mask it (AI Incident Database #1152); guardrails were added since, but caution with production data remains warranted
- Mixed review-site sentiment: about 3.7/5 across sampled G2 and Capterra reviews, with code quality on complex apps judged below what dedicated IDE agents produce

The arena’s verdict on Google Antigravity
Take Antigravity if you are already paying for Google AI Pro or Ultra, or if your primary model is Gemini 3.1: the Manager View plus embedded Chrome combo is the best agent-supervision experience shipping today, and the free tier makes trying it a no-brainer. Do not build your workflow on it if you need predictable costs: undisclosed credit conversion, repeated quota cuts and reported multi-day lockouts make budgeting a gamble, and its security record demands you keep Strict Mode on and secrets out of the workspace. Claude-first developers get more per dollar from Claude Code; teams needing full autonomy should look at Devin.
The arena’s verdict on Replit
Take Replit if you cannot or do not want to run a local dev environment: nothing else takes a non-coder from idea to a deployed, database-backed app as reliably, and Core at $20 to $25 per month is a fair trial. Treat the included credits as a starting budget, not a ceiling: serious building means overage, so set spend alerts on day one and keep the Agent away from production data. Developers who already have a local setup will get better code per dollar from OpenAI Codex or Claude Code; pure landing-page and UI builders may prefer Lovable's simpler credit model.
What the crowd says
On Google Antigravity
“Got locked out of my PAID Pro quota for a week with zero warning after one heavy Opus session. Credit math is a black box. Cannot rely on this for client work until Google publishes real numbers.”
“The embedded Chrome is underrated. Agent built a form, opened it, screenshotted the broken layout and fixed it without me saying anything. First time I have seen self-verification actually work.”
“The Manager View is what I wanted agentic coding to feel like. Kicked off 4 agents on separate features before lunch, reviewed their artifacts after. When quota holds up, nothing else comes close for free.”
On Replit
“Burned my whole month of Core credits in four days. One debugging loop cost me $40 and the bug was still there. Set billing alerts before you touch the Agent.”
“Agent 3 watching itself click through the app and fixing its own bugs is wild. Still the fastest prompt-to-deployed-URL I have used.”
“As a PM with zero coding background I shipped an internal ticket tracker in one evening. Auth, database, deployed. My eng team was honestly annoyed.”
