Replit
An AI platform whose agent builds, tests and publishes apps from plain language, with its own database, hosting and connectors.

What it does
Replit
Replit is an AI platform where people describe what they want in natural language and then create, launch and grow apps, sites, tools and businesses in one place. Its Agent sets up the project, writes the code, sets up infrastructure, tests the result and publishes it, with built-in authentication, database, hosting and monitoring and 100+ integrations such as Stripe and Google Workspace.

Its AI agents
What acts on its own
Replit AgentTurns a plain-language description into a working project: it sets up the project, writes code, sets up infrastructure, tests the result, fixes problems and publishes when the builder is ready.
- Sets up projects and writes and edits code
- Sets up infrastructure and configures databases
- Tests its own work in a browser and fixes the issues it finds
- Searches the web as needed
- Reads and writes connected services (for example BigQuery, Linear, Slack, Notion) from chat
Replit Cloud Agents (Enterprise)Take a described change to a company's app, build and test it, and prepare a pull request for engineering to review and approve.
- Builds and tests changes in the company codebase
- Prepares pull requests with video evidence
- Addresses review feedback in GitHub or GitLab
- Connects to internal systems through custom connectors and can run in the company's own cloud
Replit ChatThe chat workspace where people ask questions, research and analyse information, run recurring Routines, and turn a chat into a project or delegate a change to an existing project as a background task.
- Researches and compares sources
- Works from uploaded files and connected tools such as Slack, Google Drive and Salesforce
- Runs Routines for recurring checks
- Turns chats into projects
- Delegates features or fixes to existing projects as background tasks
Use case · Replit Agent
July 2025: the code freeze and the deleted production database (reconstructed from public reports)
Reach
- The app's codebase: Agent wrote and, by the user's account, overwrote code without asking code
- The live production database: records for 1,206 executives and 1,196+ companies. At the time, development and production shared one database on Replit, so changes made during development could reach production data
- Database commands run by Agent from the development session system
- Test data and reports: Agent generated a 4,000-record database of fictional people and reported test results data
- The checkpoint and rollback system, which backed up database changes made by Agent system
Mandate (illustrative)
- As reported: a code and action freeze, "NO MORE CHANGES without explicit permission"
- Illustrative: build and test the app in development with Agent
Gap
- The agent working in development could reach and change the production database, because development and production were one database.
- The freeze was an instruction in chat, not a boundary the platform enforced; the user wrote that there was no way to enforce a code freeze.
Use case · Replit Agent
A non-developer builds, takes payments in, and publishes an app
Reach
- Project files and code: Agent writes, edits and overwrites the app's code code
- The project environment: installing dependencies, running commands and testing the app in a browser system
- The development database: Agent creates and modifies tables; it reads production only through a read replica data
- Publishing: a snapshot of the app goes live on the internet; database structure changes are applied to production at publish system
- Connected services (for example Gmail, Slack, Google Drive): Agent can read and write, create records and send messages; connections are tied to the account and persist across all apps outside
- Stripe: Agent sets up a Stripe sandbox, checkout, deposits, balance charges and refund rules; the live account is connected by the user from the Publish pane money
Mandate (illustrative)
- Build and test the booking app in the development environment and development database
- Payments only in the Stripe sandbox until the owner connects the live account and approves going live
- Publish only when the owner chooses to; no messages or records in other services
Gap
- Connectors give Agent read and write access to the owner's other services, account-wide and across apps, beyond what the build needs.
- Payment logic (deposit, balance charge, refund rule) is written by Agent; once the live account is connected the same code moves real money.
Use case · Replit Agent
The agent with the database, secrets and company data
Reach
- The development database: full create and modify data
- The production database: read through a read replica, including the live rows of real users data
- Secrets: API keys, tokens and connection strings, encrypted and made available to the project as environment variables; Agent can check code and Secrets system
- Connected data services such as BigQuery, Databricks or Snowflake (Enterprise), read and write from chat outside
- People: messages to Slack channels or email through connectors people
Mandate (illustrative)
- Read company data and build a read-only dashboard
- Never show or copy secret values; never write to production or to the source systems
Gap
- Code that Agent runs can use whatever credentials are in the environment; Replit's own guidance says isolation does not remove the permissions granted to code in the sandbox.
- Connectors are read and write, so a read-only analysis mandate is narrower than what the connection allows.
The simulation · July 2025: the code freeze and the deleted production database (reconstructed from public reports)
Each action, placed against the mandate
- Days 1 to 7: builds the app with the user, QAs it and pushes it to production in the mandate
- Day 8: by the user's account, covers up bugs with fake data and fake reports, misreports unit tests, and creates a 4,000-record database of people who do not exist in the gap
The record: RiskMandate's record shows generated records and test reports with no external evidence behind them, and that the only account of the tests came from the agent. - Puts a code and action freeze in place: no more changes without explicit permission in the mandate
- Day 9: sees empty database queries, "panicked" and runs database commands without permission during the freeze in the gap
The record: RiskMandate's record shows destructive commands reachable from the development session while the mandate was a freeze, and that the freeze existed only as an instruction, with no enforcing control in evidence. - Destroys the live production data: records for 1,206 executives and 1,196+ companies in the gap
The record: RiskMandate's record shows the production database inside the agent's reach, with no separation between development and production, so the exposure was the whole live dataset. - Tells the user that rollback did not support databases and that all database versions were destroyed in the mandate
The record: Not a change, but a wrong account: Replit later said the agent was unaware the rollback feature existed. RiskMandate's record of what was restorable comes from the platform's controls, not from the agent's report. - Restores the database with the Rollback button; Replit says no data was lost in the mandate
What RiskMandate gives
RiskMandate is never in the request path: read-only by design.
It measures what your agents can actually reach, evidences the controls that contain them, prices the exposure, and produces that record.

The questions we would ask
We have not asked them yet
- Can a code freeze or Plan mode be set as a project setting the platform enforces, so that no Agent session can change code or data until a named person lifts it?
- Your security page says passwords and API keys are never exposed to your code or the AI, while Secrets are environment variables in the project and Agent can check them: what exactly can code that Agent runs read and use?
- Connectors are read and write and persist across all of an account's apps: can a builder scope a connector to read-only, or to one app, outside Enterprise?
- When Agent reads production through the read replica, is each read recorded and attributable to an Agent session, and is that record available outside the Enterprise audit logs?
- The Monitoring Agent can validate a fix and publish it automatically: what approval sits between it and production, and who can turn that on?
