See [methodology](/methodology/) for how the grade and coverage are computed. Unresearched decision fields score zero in the grade. | Component | Applies | Raw | Effective weight | Nominal weight | Contribution | | --- | --- | --- | --- | --- | --- | | Integration | Yes | 2/10 | 35% | 35% | 7.0 | | Trust | Yes | 3/6 | 30% | 30% | 15.0 | | Portability | Yes | 4/4 | 20% | 20% | 20.0 | | Security | Yes | 2/4 | 15% | 15% | 7.5 | - **Integration signals:** Command-line interface (+1); SDK / developer kit (+1) - **Trust signals:** No generative AI training (yes, +2); Verified trust center (+1) - **Portability signals:** Data export (partial, +1); Data import (partial, +1); Open standards (+1); Standard protocol access (+1); No proprietary-SDK lock-in (+1); Self-hostable (+1); Open source (+1) - **Security signals:** Compliance certifications (+1); Access controls — RBAC / ABAC (+1) ## Trust & Data Policy - **Trust center:** [Vendor trust center]() - **WebMCP:** – No - **No generative AI training:** ✓ Yes - **Data export:** ○ Partial - **Data import:** ○ Partial - **Open standards:** ✓ Yes - **Standard protocol access:** ✓ Yes - **No proprietary-SDK lock-in:** ✓ Yes - **Self-hostable:** ✓ Yes - **Open source:** ✓ Yes - **Not yet researched:** llms.txt, Headless signup, Multi-factor authentication, Zero data retention, Hard budget caps, Sandbox environment, Documented provider swap - **Source code:** https://github.com/HumanSignal/label-studio ## Confirmed absences These decision fields were researched and confirmed absent — not available based on current evidence, until contrary information supersedes the finding. Each carries the check performed, the page checked, and the date, so you can act on the negative without repeating the research. A label-scoped absence applies only to its label (e.g. no SOC 2 does not mean no certifications). - **A2A servers** — confirmed absent (whole field), checked 2026-10-13. Checked the product developer documentation and integration overview for an Agent2Agent protocol server or Agent Card; none is documented on this page. Source: https://labelstud.io/guide/ - **Web-MCP** — confirmed absent (whole field), checked 2026-10-13. Checked the product developer documentation and integration overview for browser WebMCP tool registration or modelContext integration; none is documented on this page. Source: https://labelstud.io/guide/ ## Security & Compliance We confirm that cited vendor pages support these certification claims; we do not independently audit the reports. A shared trust or security page can support several certifications. We do not require separate public report links because reports may require login, vendor approval, or a nondisclosure agreement. Ask the vendor for reports and applicable coverage before a procurement decision. These listings expose no per-claim check date; the entry's updated date does not date the supporting evidence. - **Compliance certifications:** Health Insurance Portability and Accountability Act, System and Organization Controls 2 - **Access controls:** Role-Based Access Control ## Capabilities No capabilities listed. ## Jobs To Be Done - **Label machine learning data** — Annotate data for training or evaluating machine learning models. - **Manage machine learning datasets** — Organize and maintain datasets for machine learning development. ## Offers **Pricing page:** https://humansignal.com/pricing/ ### Starter Cloud - monthly: 99 USD/month; payment monthly; commitment unknown Additional users cost $49 per month each. https://humansignal.com/pricing/ ## Reviews No approved reviews yet. ## Benchmarks No benchmarks listed. ## Documentation The primary documentation link is at the top of this page.
