Limits

Sizes, counts, and how long things live.

Sandboxes

TTLPer sandbox, inside the range the control plane accepts
Ready inSeconds, unless a baseline holds many files
Concurrent sandboxesA quota per organisation, and what the deployment itself can carry

A sandbox is deleted when its TTL expires, whether or not anything is using it. veris up --ttl <minutes> sets the lifetime of the sandbox you start, ttl_minutes in the environment’s entry in .veris/twin.yaml sets it for every sandbox of that environment, and the control plane’s own default applies when neither names one. veris run --fresh --ttl <minutes> bounds the sandbox that run deploys, which matters only if teardown never runs, since --fresh deletes it when the command exits.

A lifetime outside the range is refused 400, and the refusal names the bounds it accepts. A sandbox over the quota, or over what the deployment can carry, is refused 429 with the count, the limit and a Retry-After. Both the range and the quota are the control plane’s, and the quota can be raised for your organisation — ask us.

Environments

Services per environment1 to 32
Environments per organisationNo fixed cap
Snapshots per environmentNo fixed cap

A snapshot cannot be deleted while a sandbox that booted from it is still alive.

Files

Per file1 GB
Per environment20 GB
Files per environment25,000

An import that would exceed a limit is refused with the number, and nothing is partially written.

Reading a world

Rows per /veris/data pageUp to 1000
Entries per /veris/requests pageUp to 1000

/veris/data pages with limit and offset, and reports a total. /veris/requests pages with limit and since_id, the watermark that keeps only entries whose id is above it, so a poller reads what arrived since its last call; it is newest first, or oldest first with ?order=asc.

Sandbox metadata

Up to 16 key and value pairs on a sandbox, keys up to 63 characters and values up to 253. Stored and echoed back, never interpreted. Useful for tagging a fleet with run coordinates.

API keys

A key is shown exactly once when it is created, and only its hash is stored. A key cannot create another key. Creating one needs a signed-in person.

Revoking takes up to 30 seconds to apply everywhere.

Rate limits

The control plane counts concurrent sandboxes rather than calls: nothing meters how often you may call it today, and what it answers 429 to is admission — a sandbox over the quota or over what the deployment can carry, as under Sandboxes above, and too many pairings left outstanding by veris login. Tell us before you generate sustained load, or before you run a large fleet of concurrent sandboxes.
