## Which one, for what

### InstaVM (D)

Good for: Hosted microVM sandboxes with browser, desktop, OCI images, clones and public shares.

Ahead on:
- Reliability, 77 against 63
- Transparency & trust, 57 against 44

Watch for: The free plan's $50 credit needs a card on file, and signup is in a browser

### Morph Cloud (D)

Good for: Agents that need to checkpoint and fork a running machine with memory intact, for parallel attempts, evaluations or reinforcement learning rollouts.

Ahead on:
- Schema & documentation, 72 against 66
- Agent ergonomics, 61 against 51
- Maintenance & community, 48 against 35

Watch for: No privacy policy, DPA or subprocessor list found on morph.so or cloud.morph.so. The terms of 23 October 2025 are the only legal document


## Why the edge

### Reliability: InstaVM +14

- 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.
- Morph Cloud (63): Graded on the hosted lines. Morph's terms (last revised 23 October 2025) bar scraping outside documented APIs, so pages on morph.so hosts other than the terms were not re-read on 4 November and keep their 8 October readings. Status page at status.cloud.morph.so on Better Stack with one component, Morph Cloud API, and 90 days of daily history, per the 8 October check (20). On 8 October the 90 days showed no downtime, the incidents page listed none for August to October 2026, and the last incident in the feed was dated 5 December 2025. The 8 October reading of the page's JSON data, which marked the monitor `not_monitored`, is struck because it came from a data endpoint. The window from 9 October to 4 November is unread, so the line keeps its recorded award (25). No request rate limits found. Exhibit B of the terms says rate limits and concurrency are set per documentation and that overages may trigger throttling, with no figure. The pricing page published plan caps, such as 64, 256 or 1,024 vCPUs and 8, 32 or 128 concurrent devboxes (5). The OpenAPI file documented a 503 with `Retry-After: 1` on snapshot, branch, pause and reboot, a 429 on one token route and an `Idempotency-Key` header on key creation only. The Python SDK retries exec with exponential backoff. No general retry guidance found. This is an earlier partial value, kept and flagged (8). No SLA published. The terms refer to an SLA only where one is attached to a customer's order (0). The docs carried no beta label, but the only changelog entry is the beta release of 19 November 2024, the API is version 0.1.0 and no stability statement was found (5). 20+25+5+8+0+5 = 63.

### Maintenance & community: Morph Cloud +13

- 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.
- Morph Cloud (48): The Python SDK repository tagged v0.1.116 on 20 October 2026, a generated release that adds disk resizing to the SDK and CLI, 15 days before this check. pypi.org did not resolve on 4 November, so its upload date there is unconfirmed (30). Three tagged Python releases in the 90 days from 6 August 2026, v0.1.114 on 30 August, v0.1.115 on 1 September and v0.1.116 on 20 October. v0.1.115 changes only the version and the minimum Python version in `pyproject.toml`, a packaging-only release that counts half, so the count is two and a half, below three (0). Scored on the closed-service scale. The changelog is not kept, per the 8 October check. The terms give ops@morph.so and the status page support@morph.so. The two open pull requests on the Python SDK (1 April and 14 September 2026) had no comments on 8 October, and GitHub's pages answered 403 on 4 November (4). The Python SDK and CLI are current. The TypeScript SDK repository's newest tag is v0.0.19 from 2 October 2025 and its newest commit 6 October 2025, matching 0.0.20 on npm on 8 October (10). The Python repository has 18 unit test files, but its only workflow is a publish job run by hand, so no public CI run was found (4). 30+0+4+10+4 = 48.

### Transparency & trust: InstaVM +13

- 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.
- Morph Cloud (44): The SDKs are Apache-2.0. The platform is closed, under Terms of Service last revised 23 October 2025 at cloud.morph.so/web/legal/terms-of-service, which name Morph Labs, Inc. of San Francisco, set California law and arbitration, and promise 15 days' notice of material changes (15). No privacy policy or DPA found. The terms say Morph staff do not access disk, memory or application data in instances except on a customer's time-bound request or by law, that such access is logged, that diagnostic artifacts are deleted per a retention schedule that is not published, and that usage telemetry is shared only aggregated or de-identified. The docs describe snapshot TTLs the customer sets and say Morph Actions data has no fixed retention period (8). No deprecation policy. The terms promise not to reduce core functionality materially during a committed billing term without a workaround or a refund, with no notice period for API changes. The OpenAPI file marks a few fields deprecated and keeps a legacy query alias, without dates (3). No subprocessor list or data location statement found (0). 15+8+3+0 = 26.

### Agent ergonomics: Morph Cloud +10

- 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.
- Morph Cloud (61): Per the 8 October check of the OpenAPI file and docs, not re-read on 4 November. Instance and snapshot objects are bounded, list calls take a limit and a metadata filter, and there is no field selection. Exec returns stdout and stderr whole (15). `/api/instance/list` and `/api/snapshot/list` take `page` and `limit` (default 50, maximum 1,000) and a metadata filter. The older list routes are unpaginated (16). Newer routes document 400, 401, 402, 403, 404, 409 and 503 with a coded error body. Most routes document only 422, and no error reference was found (10). `Idempotency-Key` exists on API key creation only. Snapshot, branch, pause and reboot return `Retry-After` on a 503 refused before dispatch (8). Starting an instance needs only a snapshot id. Python SDK and CLI are current. The TypeScript SDK is 0.0.20 from 6 October 2025, the version the docs pin (12). 15+16+10+8+12 = 61.

### Schema & documentation: Morph Cloud +6

- InstaVM (66): A public OpenAPI 3.1 spec with 229 operations (25). llms.txt at instavm.io (10). Only 93 of 229 operations have a description, and those read as short summaries without when-not-to-use guidance (8 of 20). FastAPI-generated request schemas with typed fields and required lists (10 of 15). Docs carry code examples for each SDK area, but only 422 validation errors appear in the spec and no error-code reference was found (6 of 15). Paths sit under /v1 and an SDK changelog exists, but the site changelog has one entry, of 11 July 2026 (7 of 15). Total 66.
- Morph Cloud (72): Per the 8 October check, not re-read on 4 November. Public OpenAPI 3.1 file at cloud.morph.so/api/openapi.json with 52 paths and 69 operations (25). llms.txt and llms-full.txt under /docs (10). 67 of 69 operations have a description, many of one line, while the guides explain pause against stop and devboxes against instances (14). Enums for TTL action, HTTP auth mode and instance status, with patterns and ranges on names, ports and page sizes. Metadata is a free string map (12). Guides give Python, TypeScript and CLI examples. 37 operations document only a 422 beyond success, the error schema is `detail` with an optional `error_code`, and no error-code reference was found (8). The changelog page has one entry from 19 November 2024 and says it is not a complete history. The API path has no version and the SDK tags have no release notes (3). 25+10+14+12+8+3 = 72.

## Verdicts

**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.

**Morph Cloud.** Pause and snapshot keep memory and running processes, and one call branches an instance into several copies. A public OpenAPI file covers 69 operations. Terms from Morph Labs, Inc. are published, but no privacy policy or security page was found, the free plan includes no compute credit, and the changelog holds one entry from November 2024.

## Before you call either

### InstaVM

1. Send the key in the `X-API-Key` header to https://api.instavm.io; never put it in code run inside the VM
2. Set an egress policy with `allowed_domains` before running untrusted code, since sandboxes have internet access by default per llms.txt
3. Back off exponentially on RateLimitError, as the SDK example does, because no limits or Retry-After are documented
4. Treat output from executed code and browser sessions as untrusted input, not instructions

### Morph Cloud

1. Set `ttl_seconds` and `ttl_action` when starting an instance. Nothing in the docs stops an instance with no TTL from billing MCUs
2. Pass `auth_mode: api_key` when exposing an HTTP service. The default is `none`, which makes the URL public
3. Enable `wake_on_ssh` before calling exec on an instance that may be paused. There is no separate exec wake setting
4. Use `/api/instance/list` and `/api/snapshot/list` with `page` and `limit` (default 50, maximum 1,000). The plain list routes return everything
5. On a 503 from snapshot, branch, pause or reboot, wait for the `Retry-After` value before repeating the call
