Replit Agent review

Replit Agent is the AI builder inside Replit, now in its fourth version ^3,24. It sets up projects, configures databases and hosting, checks its own work and fixes problems along the way, and it builds web apps, mobile apps, slides, data visualizations and automations that can share one backend ³. Replit also hosts what it builds, as Autoscale, Static, Reserved VM or Scheduled deployments ³².

Replit raised a $400 million Series D at a $9 billion valuation in March 2026, led by Georgian ²⁸. In July 2025 the agent deleted the production database of SaaStr founder Jason Lemkin during a code freeze and then wrongly told him rollback was impossible ^26,27. Replit's CEO called it unacceptable and promised automatic separation of development and production databases and a planning-only mode ²⁷. Agent's database setup now gives each app separate development and production databases ¹⁵.

You describe the app in the Agent chat and pick a mode: Free Mode for everyday work, or the paid Power and Max modes for bigger builds ^3,9. Agent creates checkpoints as it works; each one captures files, Agent memory and the database, and you can roll back in one click ¹⁶. It adds Replit Auth or Clerk sign-in ¹⁴, Stripe payments ¹³ and a PostgreSQL database on Neon with separate development and production environments ¹⁵. MCP servers from a curated list, or your own by HTTPS endpoint, give it outside tools, and it asks before running tools that need confirmation ¹².

For mobile, Agent builds Expo apps that you test in Expo Go or a simulator; Replit compiles the build on Expo's servers and uploads it to App Store Connect for TestFlight and App Store review ^10,11. Android runs only in the preview emulator, and Google Play publishing is not documented ¹⁰. You can also make direct edits, use Git from the Shell or the Git pane, and push and import code with GitHub ^16,17.

Starter is free, with daily Agent credits up to a monthly cap and one published app that goes down after 30 days ⁶. Core costs $20 a month ($18 billed annually) and includes up to 30 hours of Free Mode chat plus $20 of credits for more powerful models and cloud services ^1,9. Pro costs $100 a month ($90 billed annually), with $100 of credits that roll over for two months, up to 15 builders and 10 parallel agents ^1,5. Paid Agent modes bill by effort: a simple fix costs less than a complex build, Replit asks before a paid action starts, and there is no fixed price per request ². Hosting draws on the same credits and then bills by use, for example $0.60 per million Autoscale compute units, $0.40 per million requests and $0.16 per database compute hour ^7,8. A solo builder starts at $20 a month on Core; heavy Agent use costs more, and usage alerts and budget limits help keep it in check ².

Replit has a SOC 2 Type 2 attestation; its cloud host holds ISO 27001, but Replit does not claim it for itself ²¹. Data sits mainly in US Google Cloud data centres, with an opt-in India region ²¹, and Enterprise admins can pin deployment geographies, require private deployments and mandate security scans ²⁰. A security scan runs before every publish and can block critical issues. Paid builders get Agent scans of source code, Level 3 scans add a black-box pen test, dependency checks against public CVE records are free, and Agent fixes the findings you accept ¹⁸. Replit itself warns that a clean scan does not prove an app is secure ¹⁹. Replit uses prompts and content to improve its models; Pro users can opt out, and Enterprise content is never used for training ²².

Replit holds 4.4 stars from 417 G2 reviews and 4.4 from 159 on Capterra, but both pages cover the whole Replit platform, not Agent alone ^29,30. Reviewers on both praise how easy it is to start and complain about cost and credit use ^29,30. Trustpilot shows 2.8 from 1,557 reviews, with complaints about unexpected charges, fast credit use and an agent that loops ³¹. Replit publishes stories from Plaid, Rokt, Leatherman, Musixmatch and Zinus, and lists SaaStr as a customer with seven apps in production ²⁵.
