← Back to Overnight How Overnight compares

Everyone else solves one piece.

Code generators write the software, app builders assemble it, cloud platforms host it. Not one of them will take responsibility for what that software does once it is pointed at real customer data.

02 where each one stops

Each of them owns one layer.

A compliant runtime is the layer where AI-generated software meets real customer data: isolation, a full audit trail, and policy enforcement, applied before the code runs.

  1. 01 code generators

    They stop when the code ships

    Cursor, Lovable, and v0 are very good at producing software, and their job ends the moment it exists. They carry no runtime responsibility, which is why no enterprise lists them as a subprocessor and why the app your team built on Friday has nobody accountable standing behind it.

    We think of them as partners. Keep using them, point them at the SDK, and let Overnight pick it up from the moment the code exists.

  2. 02 app builders

    They pool tenants together

    Retool and Replit will host what you make, usually on shared infrastructure built for density. The certificates look the same as ours. The structure underneath them is a different shape.

    Overnight gives every customer walls of their own and never mixes one customer’s data with another’s, which matters precisely because a model wrote the code that reads it. A dropped tenant check has somewhere to go in a pool and nowhere to go in a tenant.

  3. 03 cloud platforms

    They sell you the raw materials

    Vercel and AWS will run anything you give them, quickly and at any scale you like. The mediation, the isolation, the audit trail, and the compliance posture are still yours to build, staff, and defend.

    At Overnight those are the product, so they arrive already built and already reviewed. You are buying the half of the problem a cloud deliberately leaves to you.

  4. 04 sandboxes

    A sandbox answers a different question

    E2B, Daytona, and Modal give an agent somewhere fast and isolated to run code while it iterates. That is the right tool for the build loop, and it is a genuinely different layer from this one.

    A sandbox answers whether code can run without touching the host. A compliant runtime answers whether software can run on real customer data with a record of what it did and who approved it, weeks after the sandbox was destroyed. Most mature teams end up running both.

    The clean line between them →
  5. 05 the line nobody crosses

    Somebody has to sign the data-processing agreement

    This is the row where every other column goes blank. A code generator will not be named on your DPA, because its responsibility ended when the code existed. A cloud will name itself for infrastructure and hand the application layer back to you.

    Overnight signs on as your runtime subprocessor of record and takes responsibility for how generated software touches your data. We own what executes, so we can put our name on the paperwork.

  6. 06 why it compounds

    One approval, however many apps come after

    Every tool in this comparison leaves you approving software one application at a time. That is survivable at three apps and impossible at fifty, which is the number a team hits within a year once generation gets cheap.

    Because the controls sit on the boundary, your security team reviews one thing. Whatever your team builds afterward arrives already inside it.
