Network and edge platforms / Apoxy alternative

Apoxy.dev alternative

Apoxy supplies private networking, gateways, reverse tunnels and JavaScript/TypeScript/Wasm edge execution. It can connect an agent’s services across clusters and machines. Compare those networking and edge features with the Linux runtime and durable machine state your agent needs.

When Apoxy fits

Apoxy fits teams needing cross-network reachability, public ingress, fixed egress, API routing and lightweight edge logic. Keep those networking capabilities when they are part of the application architecture.

When to consider Sandbox0

Consider Sandbox0 for a returning agent’s isolated Linux toolchain and complete growing RootFS. You still need to design cross-cluster networking, edge logic, domain routing and any Apoxy-specific tunnels or gateway controls.

Capabilities

Apoxy and Sandbox0: what persists?

Feature comparison with documentation and verification status
Environment and runtime lifetimeApoxyGateway and tunnel lifetimes are networking controls; the cited edge platform does not establish a general Linux agent session-duration allowance.View evidence ↗Sandbox0ttl and hard_ttl default to 0 (disabled). Configure idle pause and deletion policies for the same persistent sandbox identity; an idle running sandbox still accrues compute charges.Read documentation →
Persistent filesApoxyNetwork routing, edge workers and logs do not establish a managed durable Linux disk contract.View evidence ↗Sandbox0The writable RootFS survives successful checkpoints, including software, system configuration, dependencies, and user data.Read documentation →
Whole RootFSApoxyThe reviewed edge platform does not establish whole writable RootFS lifecycle for arbitrary Linux agents.View evidence ↗Sandbox0Persistence extends beyond /workspace to paths such as /usr/local, /etc, and /home.

Release compute, keep stateApoxyTunnel connection management is different from machine checkpoint/resume.View evidence ↗Sandbox0Pause compute between tasks; resume on available capacity. Default resume starts fresh processes from the saved filesystem.Read documentation →
Memory and process stateApoxyNo arbitrary process-memory snapshot contract is established.View evidence ↗Sandbox0Experimental memory checkpoints can preserve compatible process state. Use memory: true on both pause and resume on a compatible deployment. A filesystem checkpoint alone does not preserve running processes.Read documentation →

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.

Apoxy can connect networks and run edge logic; the reviewed contract does not establish a durable automatically growing Linux RootFS. Network reachability, bandwidth scale and filesystem capacity are separate requirements.

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.

An active network tunnel or retained request log is not full-RootFS file access to a paused guest. The reviewed Apoxy docs do not establish that complete offline file interface.

The edge platform composes routing and execution

The docs describe Envoy, Kubernetes-style configuration, a gateway, JS/TS/Wasm workers and QUIC/connect-ip tunneling. Deployment options range from managed Cloud to in-VPC and standalone components. A common data plane does not establish one universal whole-Linux-filesystem or process-memory checkpoint contract.

The bandwidth meter uses the larger traffic direction

The price FAQ totals client ingress and egress separately and bills the larger amount, rather than their sum. Proxy-to-origin traffic is excluded under that definition. Bandwidth, logs/traces and TCP/UDP gateways have different allowances or charges; a GB transfer rate is not a sandbox compute-hour price.

Caps and deployment models change the bill

A hard cap serves 429 after the cap; a soft cap alerts while serving continues. The FAQ says Free defaults to its monthly bucket while Standard defaults to no cap. Premium in-VPC deployment instead uses a per-vCPU model. Confirm the selected deployment and cap behavior before comparing totals.

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.

The FAQ places in-VPC deployment on Premium with per-vCPU pricing; the Standard managed-traffic price is a separate offer. Prices cover the edge/network platform; model use and a durable agent Linux host remain separate.

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.

$6.00 compute

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 Apoxy

  1. Inventory gateways, tunnels, edge-worker code, traffic directions, cap settings and the actual managed/in-VPC plan.
  2. Use Sandbox0 for compatible durable agent execution and retain or rebuild the required network/edge layer explicitly.
  3. Test service reachability, system-state retention, RootFS growth, paused files and total bandwidth/log/gateway plus runtime/model charges.

Common questions

Is Sandbox0 a drop-in Apoxy 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.
