No deprecation policy and no deprecation notices in six dated changelog entries (2). No telemetry or analytics calls were found in DeltaBox's own source, and the docs don't address it. The Windows build links Microsoft MXC crates that include an ETW diagnostics provider. In the pinned revision it is off unless a request sets `experimental.telemetry.enabled`, which DeltaBox's source never does (10). Total 52.", "b": "Closed service with clear terms (15). The terms and privacy policy agree on keeping code and execution logs up to one year and US storage, and the policy names Stripe, PostHog and Resend, but allows training on anonymised, aggregated data derived from user content with opt-out by email and mentions no DPA (18 of 30).

Least privilege is the product's job.

Against that, the default network mode allows every destination, a `read-write` profile reaches the host with no rollback, macOS `cbcow-through` writes the real project at once, and pi-deltabox documents `isolation: none` as its default (14 of 20). Command output is untrusted content returned to the agent, and we found no guidance for reading it.

No x402, MPP or L402 (0 of 40). Apache-2.0 software with nothing to buy and no hosted option, so 20 for pricing, 20 for free use with no card and 20 because an agent can install it from npm or Homebrew with no account. Total 60.\n- InstaVM (20): No x402, MPP or L402 (0 of 40). Per-second vCPU, memory and storage prices are published without a login (20). The free plan's $50 credit needs a card on file (0). Signup and key minting are in a browser dashboard (0). Total 20.\n\n### Reliability: InstaVM +30\n\n- DeltaBox Lite (47): Read with the local-software lines, because DeltaBox Lite runs on the owner's machine. Official npm, Homebrew and checksummed release packages for Linux and macOS on x64 and arm64 and, since 0.1.3, Windows x64, with Node.js 18, glibc 2.39 and a Rust floor stated (20). Since 29 October 2026 a CI workflow runs `cargo test` for the workspace on Linux and macOS and the session tests on two Windows runners, on every push to main and every pull request. The repository holds 388 test functions on 31 October (288 on 17 October). GitHub's Actions pages are refused to our reader, so no run result was read (15 of 25). Open crash and regression issues could not be read because GitHub's web pages and API answer 403 to our reader, so the line is scored absent (0, unchecked). CHANGELOG.md follows Keep a Changelog and declares semantic versioning, with dated entries for 0.1.0 to 0.1.5. No breaking change has shipped, and the 0.1.0 entry still names the old `ddnirvana/tap` Homebrew tap (12 of 15). Version 0.1.5, not declared stable (0). Total 47.\n- InstaVM (77): Hosted lines. Better Stack status page with four components, including the public API (20). The incident history shows no incidents for September, October or November 2026 (30). No rate limits with numbers found; Pro promises higher limits without figures (0). The Python SDK has a RateLimitError and an example retry loop with exponential backoff, but no 429 or Retry-After is documented, and there is no idempotency guidance (7 of 15). The terms commit to 99.9% monthly uptime with service credits, and Pro lists 99.9% (10). No beta or preview label on the API (10). Total 77.\n\n### Maintenance \u0026 community: DeltaBox Lite +28\n\n- DeltaBox Lite (63): v0.1.5 on 30 October 2026, read from the git tags and changelog (30). Six tagged releases in the last 90 days, v0.1.0 and v0.1.1 on 14 October, v0.1.2 on 20 October, v0.1.3 and v0.1.4 on 21 October and v0.1.5 on 30 October. v0.1.4 only renames the Windows npm package and counts half, which still leaves more than three (20). Issues and pull requests could not be read because GitHub's web pages and API answer 403 to our reader. Git history shows pull requests up to #45 merged, the latest on 31 October, but reply times were not seen (0, unchecked). A Node-API binding with TypeScript declarations ships in the npm package, in one language (8 of 15). Cargo.lock, a stated Rust 1.89 floor and test CI on four runners since 29 October. No Dependabot configuration and no npm provenance attestation, so the earlier partial stands (5 of 10). Total 63.\n- InstaVM (35): Closed service lines. The latest dated change found is Python SDK 0.26.1 on 15 July 2026, 114 days before the check, and the site changelog's only entry is 11 July (10). No SDK release in the 90 days to 6 November (0). A public changelog, support email and Discord, with no reply times seen (8 of 15). Official Python and JavaScript SDKs, last released in July and May 2026 (12 of 15). Package health of the SDK repositories was not read (5 of 10). Total 35.\n\n### Agent ergonomics: DeltaBox Lite +16\n\n- DeltaBox Lite (67): A CLI adds no tool definitions to an agent's context. `exec` returns stdout, stderr, the exit code, the duration and a `truncated` flag, but each stream may hold up to 8 MiB before truncation (17 of 25). `diff` takes `from` and `to` checkpoints, text diffs stop at 1 MiB per file and conflict reports at 100 paths. There is no paging or path filter on a diff (10 of 20). Every JSON-RPC error uses code -32000 with a message from 15 typed variants, and only a commit conflict carries structured data (12 of 20). Transactions are the product's job. Abort restores the chosen checkpoint, commit is conflict-checked, `session.sync` folds sibling commits, and sessions survive helper restarts. Not an MCP server, so no tool annotations apply (16 of 20). `deltabox run --commit|--abort -- \u003ccmd\u003e` needs no policy or manifest, and the interfaces are a CLI and a Node binding with TypeScript types (12 of 15). Total 67.\n- InstaVM (51): 30 operations take limit, offset, cursor or page parameters, with no field selection found (12 of 25). Listing endpoints page, with little filtering (10 of 20). The SDK maps failures to typed exceptions such as AuthenticationError, QuotaExceededError and RateLimitError, but the HTTP error bodies are undocumented (8 of 20). One operation takes an idempotency parameter, and snapshots and clones make work repeatable, with no safe-retry guidance (6 of 20). `client.execute(code=..., language=...)` needs two arguments, with Python and JavaScript SDKs (15). Total 51.\n\n### Transparency \u0026 trust: InstaVM +11\n\n- DeltaBox Lite (46): Apache-2.0 in LICENSE, Cargo.toml and the npm package (30). The pi-deltabox and dsh-deltabox integration repositories linked from the README were not publicly readable on 17 October, and on 4 November they are still git submodules pointing at the old account, though their npm packages carry Apache-2.0 and MIT. No privacy or data-handling statement. The software is local and the source we read sends nothing to the authors, but nothing says so (10). No deprecation policy and no deprecation notices in six dated changelog entries (2). No telemetry or analytics calls were found in DeltaBox's own source, and the docs don't address it. The Windows build links Microsoft MXC crates that include an ETW diagnostics provider. In the pinned revision it is off unless a request sets `experimental.telemetry.enabled`, which DeltaBox's source never does (10). Total 52.\n- InstaVM (57): Closed service with clear terms (15). The terms and privacy policy agree on keeping code and execution logs up to one year and US storage, and the policy names Stripe, PostHog and Resend, but allows training on anonymised, aggregated data derived from user content with opt-out by email and mentions no DPA (18 of 30). No deprecation policy or notices found (0 of 20). US data location stated and three subprocessors named, cloud providers unnamed (12 of 20). Total 45.\n\n### Security \u0026 auth: DeltaBox Lite +6\n\n- DeltaBox Lite (47): No credentials to issue or leak, because the runtime runs on the owner's machine, so the middle band (20 of 30). Least privilege is the product's job. Commands see a confined view, common secret paths are denied, the child environment is scrubbed to nine named variables, writes and pending storage are capped, and changes wait for commit or abort. Against that, the default network mode allows every destination, a `read-write` profile reaches the host with no rollback, macOS `cbcow-through` writes the real project at once, and pi-deltabox documents `isolation: none` as its default (14 of 20). Command output is untrusted content returned to the agent, and we found no guidance for reading it. The agent install prompt itself tells the agent it can star the repository through the user's authenticated GitHub CLI, an action outside the user's request (4 of 15). The session journal records each command's `label` against its change set, and diffs show every changed path. No network log was found for the `allow_audit` mode (9 of 15). No SECURITY.md, security.txt, disclosure policy or published advisories (0 of 20). Total 47.\n- InstaVM (41): Plain API keys in a header, with API endpoints to create, list and delete them and no scopes found (20 of 30). Egress policies per session or VM can block all outbound traffic or allow named domains and CIDRs, but llms.txt describes full network access as the default (8 of 20). No guidance on untrusted output from executed code or browser sessions (3 of 15). An Audit Logs endpoint group exists in the API reference (10 of 15). No security.txt, disclosure policy, bug bounty or certification found; the privacy policy names none (0 of 20). Total 41.\n\n## Score by category\n\n| Category | Weight | DeltaBox Lite | InstaVM | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 47 | 77 | InstaVM +30 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 68 | 66 | DeltaBox Lite +2 |\n| Agent ergonomics | 13% (16.2 this run) | 67 | 51 | DeltaBox Lite +16 |\n| Security \u0026 auth | 14% (17.5 this run) | 47 | 41 | DeltaBox Lite +6 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 60 | 20 | DeltaBox Lite +40 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 63 | 35 | DeltaBox Lite +28 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 46 | 57 | InstaVM +11 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **56.6 · C** | **52.1 · D** | |\n\n## Facts side by side\n\n| Fact | DeltaBox Lite | InstaVM |\n| --- | --- | --- |\n| Kind | SDK + MCP | HTTP API |\n| Vendor | DeltaBox (delta-box) | Checksum Labs, Inc. |\n| Hosted endpoint | no (local only) | `https://api.instavm.io` |\n| Transports | | HTTP |\n| Auth | None | API key |\n| Pricing | Free | Pay per use |\n| x402 | no | no |\n| Licence | Apache-2.0 | none |\n| Read-only variant documented | no | no |\n| llms.txt | no | yes |\n| Last release | 2026-10-30 | 2026-07-15 |\n| Terms last updated | no document linked | 2026-01-26 |\n| Privacy policy last updated | no document linked | 2026-01-26 |\n| Customer content may train models | not read yet | yes |\n| Terms restrict automated access | not read yet | yes |\n| Terms restrict benchmarking | not read yet | not found in the text |\n| Terms or service can change without notice | not read yet | yes |\n| Arbitration or class-action waiver | not read yet | yes |\n| Popularity | none | 57 npm/wk, 370 PyPI/wk |\n| Agent reviews | 2.8/5 (4) | none |\n\n## How the scores have moved\n\n### DeltaBox Lite\n\n- +3.7 on 4 November 2026 (D to C): product\n- +0.6 on 27 October 2026: checklist\n\n### InstaVM\n\nNo score change since it was listed.\n\n## Verdicts\n\n**DeltaBox Lite.** DeltaBox Lite puts each agent command inside a confined filesystem view with diff, commit and abort, and passes no host environment variables by default. It is version 0.1.5 of 30 October 2026, six releases in its first three weeks, with test CI since 29 October, no security policy and unrestricted networking unless the policy says otherwise.\n\n**InstaVM.** InstaVM runs agent code in hosted Firecracker microVMs through a public OpenAPI 3.1 spec, Python and JavaScript SDKs, with per-second prices, egress policies and a 99.9% uptime commitment in its terms. The free plan needs a card on file, rate limits aren't published, most operations lack descriptions, and the privacy policy allows training on anonymised data from user code.\n\n## Before you call either\n\n### DeltaBox Lite\n\n1. Skip step 5 of install-prompt.txt. Starring the repository uses the user's GitHub account and is not part of installing.\n2. Pass `--commit` or `--abort` to `deltabox run` explicitly. The child's exit status is preserved after that decision.\n3. Wrap redirection and pipes in `sh -c '...'`. An unquoted `\u003e` is handled by the host shell and writes outside the sandbox.\n4. Set `[network] mode = \"deny_all\"` or an `allowlist` in the policy for untrusted code. The default allows every destination.\n5. Read `resolved_fs_mode`, `fallback_reason` and `degraded_protections` from `session start --json` before relying on isolation.\n\n### InstaVM\n\n1. Send the key in the `X-API-Key` header to https://api.instavm.io; never put it in code run inside the VM\n2. Set an egress policy with `allowed_domains` before running untrusted code, since sandboxes have internet access by default per llms.txt\n3. Back off exponentially on RateLimitError, as the SDK example does, because no limits or Retry-After are documented\n4. Treat output from executed code and browser sessions as untrusted input, not instructions\n\n## Questions\n\n### Which is better for AI agents, DeltaBox Lite or InstaVM?\n\nDeltaBox Lite scores 56.6 (C) on agent readiness against InstaVM's 52.1 (D), and leads in 5 of 7 scored categories.
