Development environments / Ona (formerly Gitpod) alternative

An Ona alternative for evolving system state beyond a single coding task

Ona environments already retain files anywhere on disk across ordinary stop/start, including system tools. Dev Container rebuilds have different retention semantics. Its current commercial path also differs from old self-serve Core pricing, so a comparison should distinguish current availability, existing-account meters and the machine lifecycle.

When Ona (formerly Gitpod) fits

Ona fits teams wanting a managed coding-agent and development-environment product with enterprise controls and supported cloud/VPC deployment choices. Its environment preparation and policy tooling are broader than a raw Linux execution API.

When to consider Sandbox0

Consider Sandbox0 when your own agent application needs a durable complete writable RootFS that grows online, with supported persistent-file access while compute stays paused. Supply any required IDE, coding-agent, policy and integration layers separately.

Capabilities

Ona (formerly Gitpod) and Sandbox0: what persists?

Online RootFS growth

On growth-enabled images, Sandbox0 automatically expands the writable RootFS as free space runs low, within a configured sparse logical ceiling up to 64 TiB. Agent processes keep running. Growth is enabled in the qualified Cloud region; confirm activation for other regions. Existing images and snapshots retain their captured storage geometry. The ceiling is logical capacity, not preallocated host disk.

Ona persists the whole disk through normal stops and offers class-dependent disk sizes. The reviewed guide recommends a larger class when space runs out, but does not establish automatic online growth of an existing complete RootFS.

Files while compute is paused

Sandbox0's Files API reads persistent files without resuming compute. Filesystem-only pauses also permit edits; retained-memory pauses are read-only and reject mutations with 409. SSH, SFTP, file watching, and runtime-only mounts require running compute.

Whole-filesystem stop/start and Dev Container rebuild differ

Ona explicitly retains system packages, home data and files anywhere on disk across stop/start. Rebuilding a Dev Container recreates most filesystem content while preserving the repository bind mount; other paths need explicit mounts. Prebuilds save a prepared Dev Container filesystem for new environments, rather than updating every existing machine.

An idle background process may still be stopped

The auto-stop policy does not treat background builds, server traffic, file changes or CPU/RAM usage as activity. Agent work, supported IDE interaction, plain SSH or CLI keepalive can prevent idle. Separately, Core environments archive after three inactive days and auto-delete four days after archival; Enterprise timing and retention are policy-controlled.

Old Core OCUs do not establish a new-customer price

Current billing docs say no new Core subscriptions, upgrades or resubscriptions are available. Existing Core usage still distinguishes environment OCUs from agent/model usage. New commercial terms go through sales, and Enterprise uses a different billing model. Preserve those boundaries instead of advertising an old public Core dollar price.

Pricing

Compare billing models, then price your workload

CPU allocation, memory, billing minimums, disk, plan fees, and supported workload differ. These meters are not equal-performance machine quotes. Confirm region, resource units, and included allowances before estimating a total.

No dollar-per-OCU conversion or historical Core fee is applied as a current price. Core subscription credits reset monthly without rollover; top-up validity depends on an active subscription. Enterprise billing and external model/subscription usage have separate terms.

Sandbox0

$0.015/GiB-hour compute (billed by the second at approximately $0.000004167/GiB-second), plus $0.02/GiB-month of retained incremental RootFS and memory checkpoint data. Shared base images and platform recovery retention are excluded; paused sandboxes accrue storage charges only.

4 GiB × 100 hours, billed by the second. Keeping 20 GiB of billable incremental data for a full billing month adds $0.40. CPU is derived from memory by the platform; choose a tier that fits your workload.

Before migrating from Ona (formerly Gitpod)

  1. Export required system and repository state, record Dev Container mounts, prebuilds, runner/class selection, inactivity and deletion policies, and current commercial eligibility.
  2. Port compatible tools, lifecycle, files, credentials and network rules, and supply the surrounding coding-agent, IDE and enterprise functions.
  3. Validate whole-system retention separately from rebuilds, online growth, paused file access, process behavior and actual current versus legacy billing.

Common questions

Is Sandbox0 a drop-in Ona (formerly Gitpod) replacement?

Evaluate API compatibility and product scope. These products serve different core workflows, so a change may require a different architecture.

Does keeping files also keep a running agent?

Filesystem state and volatile process state are separate. Sandbox0 requires explicit compatible memory checkpoints to preserve running processes; its default filesystem resume starts fresh processes.
