Scores are editorial product assessments — job fit, likely output quality, ease of adoption, and operational cost — not lab benchmarks, and no tool here has a published hands-on result. How we score.

- Bolt's security page says code and prompts are never used to train foundation models, while the Privacy Policy permits aggregated, anonymized, or de-identified AI content to improve AI performance and describes plan-dependent training controls. The exact boundary between 'foundation-model training' and other model/service improvement is not defined.
- The public Privacy Policy does not enumerate which plans receive training opt-out controls.
- The commercial-use statement does not provide a non-infringement warranty for generated code.
Official documentation says Bolt offers Standard and Max agents; Standard is available on Free, while Max requires a paid plan. Bolt's commercial-use documentation states that all code created with Bolt and StackBlitz is the user's code and may be used for any legal purpose, including commercial purposes. StackBlitz's Terms state that it does not claim ownership of data, content, or other material submitted, published, or transmitted through the service. The Privacy Policy says Bolt may use AI Inputs and Outputs to operate, maintain, and improve the service, including AI performance, reliability, and safety, using aggregated, anonymized, or de-identified data. The Privacy Policy says training/improvement opt-out controls may depend on account type or plan, while third-party AI providers process Inputs to provide services to Bolt under contractual confidentiality and data-protection obligations.
Free. Browsing the plugin catalogue and submitting a public plugin repository cost nothing - stated in the catalogue's own FAQ ("list your public repository for free") and in the live https://hol.org/plugins/llms.txt, which sells nothing. No paid tier exists for the catalogue itself; paid credits apply to other HOL registry operations, and HOL Guard is a separately priced product with its own plans. Verified 2026-10-14 from the live /plugins/llms.txt plus the archived catalogue page, because live catalogue HTML is served behind a Cloudflare challenge and returned 403 to every scripted client.

- No general site-wide Terms of Service was located. The footer link labelled "Terms of Service" resolves to https://hol.org/points/legal/terms (a points-programme legal page) in both the live app shell and the archived pages, and that page's actual scope could not be read because live HTML is Cloudflare-challenged. Treat the recorded rights_url as the only terms link found, not as confirmed coverage of the catalogue.
- Catalogue size disagrees between HOL's own surfaces: the archived catalogue page (2026-08-31) read "Showing 243 plugins across 16 ecosystems" while the live /plugins/llms.txt says "205 catalog plugins". The listing therefore quotes no figure.
- Retention periods and named subprocessors are asserted in the privacy summary ("the complete policy names categories of providers and explains ... retention") but the full Privacy Policy, stated as last updated 2026-06-29, could not be read from this host. Retention and processor specifics are unverified.
- Security scoring is a fallback static catalogue scan, not a live exploit test - disclosed by the site itself in its FAQ and llms.txt. Any trust score should be read as a weak signal, and the listing's pros/cons say so.
- The privacy summary warns that information written to a public blockchain can be visible to third parties and may be permanent even after an off-chain account is deleted. This applies to HOL Points and registry features rather than the plugin catalogue, but is not itemised per product.
Submitted via the site form by the vendor (name "HOL Plugins", url https://hol.org/plugins, category Development, contact michael@hol.org) - FormSubmit mail timestamped Thu, 2026-10-15 00:22 UTC, i.e. 2026-10-14 in the site's Pacific working date. Editorial entry written independently; no vendor copy reused and no revenue figure inferred. Operator identity verified twice: (1) the site's own About and Contact pages state that "Hashgraph Online DAO LLC operates hol.org", give the business address 852 Long Island Rd, Majuro 96960, Marshall Islands, and publish +1 347-705-7394 and support@hol.org; (2) independently, the GitHub organisation "hashgraph-online" (display name "HOL (Hashgraph Online)", 66 public repositories, created 2024-02-18) lists hol.org as its blog, Marshall Islands as its location and support@hol.org as its email, and its hol-guard repository lists https://hol.org/guard as its homepage (Apache-2.0, 896 stars, last pushed 2026-10-15). Submitted contact michael@hol.org is a real mailbox: SMTP RCPT probe against the domain's own Google Workspace MX returned 250 2.1.5 OK, while a random local part returned 550 5.1.1, proving the domain is not a catch-all. Provenance limits, stated plainly: hol.org serves its HTML, its sitemap.xml, its OpenAPI document and its live API endpoints behind a Cloudflare challenge (403 to every scripted client; only the llms.txt surfaces load), and the interactive browser was unavailable on this host, so the catalogue, About, Contact and Privacy pages were read from Wayback snapshots (catalogue 2026-08-31; About 2026-09-19; Contact 2026-09-19; Privacy 2026-09-24) and cross-checked against the live surfaces that do load: /plugins/llms.txt, /guard/llms.txt, robots.txt and the live 404 app shell, which carries the site's full navigation. Ownership is not in question on any reading.
