# ascii

> Agent orchestration over Telegram, running on box's VM infrastructure.

ascii is the agent-facing product built on box's VMs; its own comparison page describes it as a "pocket CTO on Telegram" doing multi-repo dispatch and cross-VM agent communication. Everything toolweight records about its runtime comes from that same vendor table: the box capability set minus SSH access and minus the 1000-concurrent-VM claim. None of it has been checked independently, and no pricing, boot-time or isolation detail is published there at all.

## Where it is compared

### [Sandbox providers](https://toolweight.com/compare/sandbox-providers)
Ranked **#13 of 20** on default weights.
| Field | Value | Confidence | Verified | Source | Note |
| --- | --- | --- | --- | --- | --- |
| Cold start | - | Unknown | - | - | toolweight has not measured ascii, and the vendor's comparison table publishes no boot figure. |
| Cold start (claimed) | - | Unknown | - | - | ascii is absent from the "<500ms time to VM-ready" row and publishes no other figure. |
| Isolation | - | Unknown | - | - | The table claims Docker inside the VM but names no hypervisor or isolation technology. |
| Root in guest | ● | Inferred | 2026-07-23 | https://box.ascii.dev/compare | Derived from the "Docker inside the VM" row: a Docker daemon in the guest implies root. The table claims Docker, not root. Transcribed from ASCII's own comparison table; not verified by toolweight. |
| Egress control | - | Unknown | - | - | The table covers what the network can reach, not what the platform can restrict. |
| Max runtime | - | Unknown | - | - | The "No session cap / runs 24/7" row is a marketing statement, not a published runtime ceiling, and this page's 24 h ceiling is reserved for platforms with a documented absence of a limit. Left unknown rather than awarded the maximum. |
| Persistent FS | - | Unknown | - | - | Not a row in the table. |
| Snapshot & fork | ◐ | Inferred | 2026-07-23 | https://box.ascii.dev/compare | Listed under "Fast disk snapshots / branching" and not under "Process fork", disk-only cloning without live memory forking, this field's partial. Derived from a presence and an absence rather than stated; the absence is ASCII conceding a gap in its own product, which is why it is credited at all. Vendor-published, unverified. |
| Custom images | ◐ | Inferred | 2026-07-23 | https://box.ascii.dev/compare | Derived from "BYO repos + arbitrary setup script", a base extended by a setup script, this field's partial. Nothing is said about arbitrary OCI images, so the mapping is ours. Vendor-published, unverified. |
| GPU | - | Unknown | - | - | Not a row in the table. |
| Runtimes | - | Unknown | - | - | Not a row in the table. |
| Preview URLs | ◐ | Inferred | 2026-07-23 | https://box.ascii.dev/compare | Derived from two rows that are not about preview URLs, "Dedicated IPv4 per VM" and "Full TCP/UDP + BYO domain": reachable ports on a domain you own rather than a first-party HTTPS URL from the API. The mapping is ours. Vendor-published, unverified. |
| Browser inside | - | Unknown | - | - | Not a row in the table. |
| File up/download | - | Unknown | - | - | The "SSH access" row lists box, exe.dev, Namespace, Daytona, Codespaces, Cursor SDK and Islo, not ascii, so no SSH-based file movement is claimed, and no file API is described either way. The vendor omitting its own product from a row is at least a claim against interest, but it still settles nothing about this field. |
| Sydney region | - | Unknown | - | - | The table says nothing about regions. |
| Concurrent limit | - | Unknown | - | - | ascii is absent from the "1000+ concurrent VMs ergonomically" row, so that scale is not claimed; no other figure is given. |
| MCP server | - | Unknown | - | - | Not a row in the table. |
| SDKs | - | Unknown | - | - | Not a row in the table. |
| Streaming output | - | Unknown | - | - | Not a row in the table. |
| Price / hour | - | Unknown | - | - | No rate for a comparable vCPU/RAM shape is published in the table or alongside it. |
| Meter | subscription | Inferred | 2026-07-23 | https://box.ascii.dev/compare | Derived from the "Flat pricing" row and mapped to subscription because that is this field's option for a flat fee rather than a meter. The table never uses the word. Vendor-published, unverified. |
| Idle cost | - | Unknown | - | - | Not a row in the table. |
| GitHub stars | - | Unknown | - | - | - |
| Funding | - | Unknown | - | - | - |
| Shipped | - | Unknown | - | - | - |
| Positioning | A pocket CTO on Telegram: multi-repo dispatch and cross-VM agent comms, running on box. | Vendor-claimed | 2026-07-23 | https://box.ascii.dev/compare | Paraphrased from ASCII's own comparison page. |

**Verdict.** The only row here where the product is the agent layer and the VM is an implementation detail, ascii is ASCII's Telegram-driven orchestration sitting on box's infrastructure, so its capability cells are box's minus SSH and minus the concurrency claim. Every one of them is transcribed from ASCII's own comparison table and none is verified. Judge it as an agent harness with a VM attached, not as a sandbox API, and expect to establish the fundamentals, isolation, price, boot time, yourself, because the table does not address any of them.
