The short version

  • Only CodeSandbox has a free tier, so it costs nothing to try first.
  • Each has a real cost: CodeSandbox detailed paid plan pricing was not published on the accessible pages, making cost comparison difficult.; Semperis scope is limited to Active Directory, Entra ID and Okta, so an organisation whose critical identity lives elsewhere gets little from it, and the recovery value declines in direct proportion to how much has already moved off on-premises AD.
  • They diverge on capability: CodeSandbox covers Instant sandboxes, Semperis covers Active Directory Forest Recovery.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

CodeSandbox

  • Running AI agent-generated code safely in isolationnot Semperis
  • Prototyping and sharing web projects in-browsernot Semperis
  • Executing untrusted code for a code playground productnot Semperis
  • Using sandboxes as ephemeral CI/CD build environmentsnot Semperis

Semperis

  • An organisation that cannot answer an auditor or insurer asking how long it would take to rebuild Active Directory after a destructive attacknot CodeSandbox
  • Post-incident recovery where domain controllers are compromised and restoring from system-state backup would reintroduce the attacker's footholdnot CodeSandbox
  • Continuous detection of privileged group changes and directory-level tampering that domain controller security logs missnot CodeSandbox
  • Hybrid estates where AD, Entra ID and Okta all matter and no single tool currently shows changes across the threenot CodeSandbox

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

CodeSandbox

  • Detailed paid plan pricing was not published on the accessible pages, making cost comparison difficult.
  • Focus has shifted toward programmatic sandbox infrastructure, which may be less approachable for casual users just wanting a quick online editor.
  • Public sandboxes are visible to others by default, which is not ideal for proprietary code.

Semperis

  • Scope is limited to Active Directory, Entra ID and Okta, so an organisation whose critical identity lives elsewhere gets little from it, and the recovery value declines in direct proportion to how much has already moved off on-premises AD.
  • The licence buys tooling, not a proven runbook: forest recovery is only worth what your last rehearsal demonstrated, and a plan that has never been executed end to end in a lab is an untested assumption regardless of what was purchased.
  • It overlaps with backup and directory management products from Quest, Veeam, Commvault and others, so the buyer must argue internally why a dedicated product is needed alongside a backup contract that already claims to protect Active Directory.
  • Running Directory Services Protector well requires someone who understands AD internals, replication metadata and Tier 0 attack paths, and without that person the alerts on privileged changes are either ignored or auto-reverted in ways that break legitimate administration.
  • Licensing is driven by identity object counts, so directories carrying years of stale user accounts and service principals pay for objects that should have been deleted, and the cleanup project that would reduce the bill is the one nobody has time for.

Questions people ask

Is CodeSandbox or Semperis better?
Neither clearly leads. CodeSandbox starts at Free and Semperis at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, CodeSandbox or Semperis?
CodeSandbox has a free tier; the other does not. Paid plans start at Free for CodeSandbox and On request for Semperis.
Does CodeSandbox or Semperis run on more platforms?
CodeSandbox runs on web, api. Semperis runs on Web.
Can I use CodeSandbox for free?
Yes. CodeSandbox has a free tier, so you can try it without paying. Semperis starts at On request.
What is CodeSandbox best used for?
CodeSandbox is most often used for running ai agent-generated code safely in isolation, prototyping and sharing web projects in-browser, executing untrusted code for a code playground product, using sandboxes as ephemeral ci/cd build environments. Of those, running ai agent-generated code safely in isolation and prototyping and sharing web projects in-browser are not what Semperis is typically brought in for.
What can CodeSandbox do that Semperis cannot?

Answered from the vendors’ own pages

CodeSandbox: Does CodeSandbox offer a free tier?

Yes, CodeSandbox offers a free option available on the platform. Users can start for free.

Source
Semperis: Does this replace my backups?

No. It replaces the Active Directory recovery procedure specifically. You still need backups for everything else, and the point of Semperis is that a generic system-state backup of a domain controller is a poor way to recover a forest because it restores the operating system along with whatever compromised it.

CodeSandbox: Where can I find CodeSandbox's pricing details?

CodeSandbox maintains a dedicated pricing page, but specific tier names, feature breakdowns, and costs are not displayed on the landing page.

Source
Semperis: Is it useful if we are cloud-only on Entra ID?

Partly. Directory Services Protector covers Entra ID and Okta for change tracking and posture, but the forest recovery product, which is the strongest reason to buy, applies to on-premises Active Directory. A genuinely cloud-only organisation should weigh it against Microsoft's own tooling.

Semperis: Are Purple Knight and Forest Druid really free?

Yes, both are free downloads with no licence requirement, and they are widely used by organisations that are not Semperis customers. They are also, transparently, the top of the sales funnel.

Semperis: How long does forest recovery actually take?

The honest answer is whatever your rehearsal took. The vendor's case is hours instead of days, and automation genuinely removes most manual steps, but the number that matters for your board is the one from a test in your own environment.

Semperis: Does it require agents on domain controllers?

It collects directory changes from the AD replication stream, which is what lets it see changes that bypass the security log. Deployment details vary by product and version, so confirm the exact architecture against your domain controller change-control rules.
