Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Maintenance & community Daytona +45

Daytona 80

v0.227.0 of daytona/clients on 29 October 2026 (30). 24 stable releases from v0.204.0 (11 August) to v0.227.0 (29 October), plus v2.0.0 alphas from 24 October (20). Core development went private in June 2026, and the old public repository keeps its open issues with a notice that it gets no further updates. Public changelog and releases, scored on the closed-service scale (10). Current official SDKs in five languages (15). CI workflows for PR checks, end-to-end tests and publishing exist in the clients repository, but their pass state couldn't be read (5). 30 + 20 + 10 + 15 + 5 = 80.

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.

Security & auth Daytona +32

Daytona 73

API keys with per-action scopes (write:sandboxes separate from delete:sandboxes, plus snapshot, volume, audit, secret and billing scopes), an expiry date and immediate revocation, and manager keys that issue scoped child keys at runtime. The docs say any valid key in the organisation can reach a running sandbox whatever its scopes, so 27 of 30 (27). Container sandboxes get their own namespaces and resource limits on a shared kernel, while Linux VM and Windows classes get their own kernel (6). Tier 1 and 2 organisations get restricted network access that can't be changed per sandbox, and full internet with per-sandbox allow lists starts at Tier 3 (5). We found nothing on keeping credentials out of the sandbox or on running untrusted code (5). Audit logs behind their own key scope, log streaming and webhooks (15). An organisation-wide security policy (security@daytona.io or GitHub private reporting, acknowledgement within 5 business days, discretionary rewards) covers app.daytona.io and the clients repository. The SafeBase trust centre lists SOC 2 Type 1 and Type 2, ISO/IEC 27001 and HIPAA, with reports and a pen-test summary on request. Four advisories were published on GitHub in June 2026. No security.txt (404 on 2 November), and a discretionary reward doesn't count as a bounty. Read as modal-sandboxes' 15 (15). 27 + 6 + 5 + 5 + 15 + 15 = 73.

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.

Payments & pricing Daytona +30

Daytona 50

No x402, MPP or L402 (0). Per-second prices published per vCPU, GiB of memory, GiB of storage and GPU, re-read on 2 November (20). $200 of compute, "no credit card required" (20). Stripe Projects lists Daytona, so an agent can create the account through the operator's Stripe login, per the 1 October check (10). Total 50.

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.

Schema & documentation Daytona +21

Daytona 87

Three public OpenAPI files, for the main API (OpenAPI 3.0.0, 138 paths and 170 operations on 2 November), the in-sandbox toolbox API and analytics (25). llms.txt and Markdown pages (10). The docs say what each sandbox class is for and what only VM classes can do (15). Typed fields from the spec, with the sandbox class an enum of linux-vm, container and windows (12). The 429 error body is documented and SDK pages carry examples, but we found no error-code reference (10). A public changelog (newest entry 0.225.0 on 16 October 2026) and release tags (15). Total 87.

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.

Reliability Daytona +8

Daytona 85

Better Stack status page at status.app.daytona.io with per-service history, read from its RSS feed and incident pages on 2 November (20). The two Windows runner outages (31 July and 1 August) have left the 90 days from 4 August. The window holds a degradation of new sandbox creation in us-central-1 (11 August, 17.5 hours), elevated creation errors for 4 minutes (4 September), a builder queue backlog (12 September), sandbox listing degraded on 1 and 30 October, reduced GPU capacity (16 October), some dashboard settings unavailable (22 October) and a provider outage on a subset of US runners (29 and 30 October). Each is one region, one endpoint or a subset of runners, so partial and minor (20). Rate limits published per tier, 10,000 to 50,000 general requests and 300 to 600 sandbox creations a minute (15). 429s carry Retry-After-{throttler} and X-RateLimit-* headers, and the docs advise exponential backoff (1s, 2s, 4s, 8s). No idempotency keys found (10). An SLA page (last updated 22 August 2025) commits to 99.95% monthly uptime with service credits for Tier 4 and above (10). GA (10). 20 + 20 + 15 + 10 + 10 + 10 = 85.

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.

Transparency & trust Daytona +7

Daytona 64

SDKs and API clients are Apache-2.0 and the CLI is AGPL-3.0, but the platform code went private in June 2026 (20). Privacy policy and terms (both updated 22 August 2025) and a DPA (last updated 13 October 2026) that returns or deletes customer personal data at termination or on request. The docs say stopped, paused and archived sandboxes are kept until you delete them, with no retention period after deletion (15). Breaking changes appear in release notes, with no deprecation policy or dated notices found (5). Shared regions in the US and EU are named, and the DPA points to a sub-processor list with service and location in the trust centre, with 30 days' email notice of changes. The trust centre shows Latitude.sh, Leaseweb, OVHcloud and Stripe, and we couldn't read the locations (15). 20 + 15 + 5 + 15 = 55.

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.

How the scores have moved

Verdicts

Daytona

API keys with per-action scopes let an agent create sandboxes without deleting them, and an SLA commits to 99.95% uptime. The container class shares the host kernel, only VM classes get their own, and Daytona fixed two High cross-tenant flaws in June 2026.

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.

Before you call either

Daytona

  1. Pick a Linux VM class for untrusted code or when memory must survive a pause. Container sandboxes stop and archive instead
  2. Set autoStopInterval yourself. The 15-minute idle default can stop a sandbox while the agent is still thinking
  3. Give the agent a key without delete:sandboxes if it shouldn't destroy work
  4. Read Retry-After-{throttler} on a 429 before retrying sandbox creation
  5. Check the organisation's tier before relying on outbound calls from inside the sandbox

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
