How 20 leading ATS platforms compare on compliance, AI capability, transparency, buyer-friendliness and customer outcomes, benchmarked against the EU AI Act taking effect on August 2, 2026.
We tested 20 leading applicant tracking systems across 40 criteria. Each platform was scored against publicly available evidence as of May 5, 2026.
The compliance dimension produced a 14-point spread between best (28/30) and worst (14/30), wider than any other dimension. AI capability, where most vendor marketing is concentrated, produced only a 10-point spread.
Ashby (86), TenPerZent (84), Workable (75), and Personio (72, tied with Recruitee). The leader cluster shares one trait: each invested in compliance infrastructure ahead of the regulatory deadline rather than retrofitting after.
Vendors that publish their pricing average 113% NRR. Vendors that gate pricing behind enterprise sales average 102%. Customers of opaque vendors report 22–40% renewal increases.
Ashby, Greenhouse, and TenPerZent provide candidate-level explanations of AI-driven scores in plain language. Explainability is not yet a US regulatory requirement, but is mandatory under Article 86 of the EU AI Act.
Buyers who selected an ATS in 2024 without compliance criteria are spending $50K–$200K in 2026 retrofitting audit logs, explainability, EU data residency, and AI Act documentation. For most companies, this exceeds the cost of switching to a compliance-native ATS.

Highlighted row: TenPerZent (publisher of the Index. See Disclosures).
Compliance 24 · AI 23 · Transparency 18 · Buyer 13 · Outcomes 8
The category-leading AI ATS for scaleups. Built analytics-first, with the deepest data model of any platform tested. AI features ship with explainability defaults, audit logs, and model-change notifications baked in. EU AI Act provider documentation was published in January 2026, earlier than any competitor.
Vulnerability. Pricing is published but starts higher than SMB-friendly competitors. Platform depth is overkill for teams under 50 and adds onboarding friction.
Best for: Series A→D scaleups · Pricing: From ~$300/mo
Compliance 28 · AI 19 · Transparency 18 · Buyer 13 · Outcomes 6
Compliance-native ATS positioned for the August 2026 enforcement deadline. The only platform tested that ships EU AI Act provider documentation, NYC AEDT bias-audit automation, EEOC explainability defaults, and configurable EU data residency for AI inference as standard, not as a paid add-on.
Vulnerability. Newer than Greenhouse or Workable, with a smaller customer base and fewer third-party integrations natively. Disclosure: TenPerZent built this Index. See Methodology.
Best for: Compliance-first SMBs · Pricing: Free tier · Pro from €79/mo
Compliance 18 · AI 19 · Transparency 17 · Buyer 13 · Outcomes 8
The workhorse SMB ATS, with strong AI sourcing. Workable's 400M-profile AI Sourcing engine remains best-in-class for top-of-funnel AI. Pricing is transparent. Implementation is among the fastest in the category. Most teams are live within 7 days.
Vulnerability. EU AI Act readiness lags significantly behind Ashby and TenPerZent. The 400M-profile dataset triggers Article 27 FRIA obligations many customers haven't completed.
Best for: SMB high-velocity hiring · Pricing: From $299/mo
Compliance 27 · AI 17 · Transparency 11 · Buyer 9 · Outcomes 8
The DACH HR-suite leader, EU-native by design. Compliance posture is unmatched among full HR suites: GDPR-first architecture, EU data residency standard, and a robust DPA. Strong for European Mittelstand and US companies hiring heavily in Europe.
Vulnerability. Pricing transparency is the lowest of any top-10 vendor. AI features lag the AI-native leaders. The ATS module is one of many priorities inside a broader HR suite.
Best for: European Mittelstand · Pricing: Quote-only
Compliance 22 · AI 16 · Transparency 15 · Buyer 12 · Outcomes 7
EU-native ATS strong on collaborative hiring. GDPR-first architecture and Dutch data residency are credible compliance signals. Product UI is among the cleanest in the category and works well for distributed teams.
Vulnerability. AI features feel late to ship. Most are integrations rather than native. Product velocity has slowed since the Tellent merger. EU AI Act provider documentation is partial.
Best for: EU SMBs, design-led hiring · Pricing: From €199/mo
These vendors scored below 18/30 on the Compliance Readiness dimension based on the public evidence we could find as of May 5, 2026. A low score reflects gaps in publicly available documentation, not a determination of legal compliance, and not a prediction about any vendor's future. Several of these platforms are excellent in their primary strengths and are actively investing in compliance.
| Rank | Vendor | Compliance | Where the gap is |
|---|---|---|---|
| #16 | Breezy HR | 14/30 | Strong on ux simplicity; less public evidence on ai act gap. |
| #17 | JazzHR | 14/30 | Strong on affordable starter; less public evidence on dated, us-only. |
| #18 | Recruiterflow | 14/30 | Strong on agency workflows; less public evidence on compliance gap. |
| #10 | Manatal | 15/30 | Strong on ai marketing claims; less public evidence on compliance maturity. |
| #12 | Zoho Recruit | 16/30 | Strong on lowest tco; less public evidence on dated ux. |
| #11 | BambooHR | 17/30 | Strong on hris integration; less public evidence on limited ats depth. |
Inclusion in this list is not a claim that any vendor is non-compliant, will face enforcement, or cannot become compliant. Scores reflect only the public evidence available to us at the time of writing. Every vendor will have an opportunity to provide additional evidence before v1.1.
A 100-point scoring framework distributed across five weighted dimensions. All scoring used publicly available evidence as of May 5, 2026.
EEOC AI guidance, NYC AEDT, Illinois Video Interview Act, CA/Colorado AI laws, EU AI Act high-risk classification, GDPR Article 28 DPA, ADA accommodations, OFCCP, ISO 27001, SOC 2 Type II, EU data residency.
Resume parsing AI, candidate matching, AI sourcing, AI interviews, explainable AI, bias testing, audit logs, score explanations, hiring-manager AI, agentic / multi-step workflows.
Public pricing, security documentation, AI methodology disclosure, bias-test results, sub-processor list, uptime metrics, customer reviews, change log / roadmap.
Self-service trial, <14-day implementation, migration support, contract terms (auto-renew, exit clauses), Net Revenue Retention disclosure.
G2 average rating, G2 review count, customer-base scale, time-to-value claims, annual customer growth.
In 2024 RFPs, compliance averaged the third-highest weight after features and price. In Q1 2026 RFPs we reviewed, compliance moved to first.
Vendors split into large proprietary databases (Workable, hireEZ, SeekOut) versus connector-based aggregators (Ashby, TenPerZent, Findem). Proprietary databases face increasing GDPR Article 6(1)(f) pressure.
Of vendors valued under $2B, 11 of 14 publish meaningful pricing in 2026, up from 4 of 14 in 2024. Above $2B valuation, 0 of 6 publish.
BambooHR, Personio, Rippling, Paylocity and Factorial all expanded their ATS modules through 2025. The trade-off: ~12 points lower on AI capability, but lower HRIS integration friction.
Of the 20 platforms tested, only 3 ship documented agentic capabilities; 8 have committed to 2026 roadmap delivery. This is where R&D investment is concentrating.

TenPerZent built this Index. We are also one of the 20 vendors scored. We addressed this conflict in three ways: (1) the methodology is fully published; (2) scoring evidence for TenPerZent is held to the same publicly-verifiable standard as every other vendor; (3) we held TenPerZent's score below #1 where data supported a competitor scoring higher. Ashby outranks TenPerZent overall in this v1.0.
Public information only. All scoring used publicly available evidence as of May 5, 2026: vendor websites, customer-facing documentation, G2 / Capterra reviews, Trustpilot, regulatory filings, published case studies and vendor blog posts.
Vendors will have right of reply. All 20 vendors will be invited to provide additional evidence before v1.1 (planned September 2026). Where evidence is provided, scoring will be revised. Each revision will be logged.
Reproducibility. The scoring rubric, weights and per-criterion definitions are published. Any third party with access to public information can replicate our scores within ±5 points.

Inadvertent errors or omissions are possible despite our review process. Scores reflect our subjective interpretation of the public evidence available at the time and are not a certification, endorsement, accusation, legal opinion, regulatory determination or financial advice. A low score on any dimension is a measure of publicly available evidence, not a statement that a vendor is non-compliant, that its customers will face enforcement, fines or legal action, or that any specific outcome will occur.
