Agentic AI Comparison:
project-mariner vs Querix
(listing unavailable)vs
Introduction
Project Mariner and Querix are assessed for their documented purposes, access, cost clarity and integrations. Project Mariner’s original service is closed; it is historical context, not a currently adoptable option. Querix: Current Querix is a custom enterprise-assistant platform with knowledge grounding, multi-model use and no-code configuration for business/customer workflows. Assess this counterpart’s own current setup and purpose rather than assigning successor Gemini features to Mariner.
Overview
project-mariner
Project Mariner was Google’s experimental browser agent for observing pages and carrying out requested multi-step web tasks. The official 2024 demo is sped up and historical; its published performance is not our listing autonomy score.
Google’s rendered official landing page says Mariner shut down on May 4, 2026 and directs visitors to Gemini Spark for complex tasks. The original service is hidden. Gemini Spark is a separate service with its own capabilities and plans.
There is no current standalone Mariner offer. Its former Ultra access or historical price cannot be used for a present purchase recommendation.
Former browser/Chrome execution is historical. The original retired service has no active user-facing integration; successor Gemini/API tools are separate products.
Querix
Current Querix is a custom enterprise-assistant platform with knowledge grounding, multi-model use and no-code configuration for business/customer workflows. It is not only the chat/data workspace guessed in the old comparison.
Current signup/docs and enterprise pages are accessible. Businesses configure knowledge, tools and permissions.
The opened pricing page lists Free 50 monthly queries, Starter EUR49/month with 1,000 and Pro EUR199/month with 5,000, plus custom Enterprise. Selected account/storage/admin allowances differ; a formatting discrepancy in the comparison table does not justify inventing a different quota.
Current official pages describe CRM/ERP/internal data connections, explicitly naming Salesforce and SAP, plus developer docs. Confirm deployment access and required connector actions.
Editorial ratings · 1–10, higher is better
These scores express our judgement of the cited product facts. They are not measured performance benchmarks. Each product is assessed for its stated purpose; a higher score does not make different workflows interchangeable.
Evidence gaps lower confidence and affect the relevant judgement. Unknown pricing does not mean free access. Research prototypes and retired products retain their historical scope, with adoption ratings reflecting current access.
Ratings assessed: 2026-10-09. Source verification dates may differ.
Documented capability: How useful and complete is the documented workflow for the product's stated purpose?
- 1–2: No usable current workflow established, or only an unsupported promise.
- 3–4: Historical, experimental or very limited workflow; substantial delivery gaps.
- 5–6: Concrete but narrow workflow, or promising research requiring specialist review.
- 7–8: Substantial documented end-to-end workflow with useful controls or customization.
- 9–10: Exceptionally complete documented scope and controls; reserve 10 for unusually strong evidence.
Ease of adoption: Can the intended user obtain and set up a usable product today?
- 1–2: Discontinued, unavailable, waitlisted, or no usable deployment path verified.
- 3–4: Archived software, restricted research/preorder access or uncertain current service access.
- 5–6: Developer-managed setup, significant configuration or sales-led implementation.
- 7–8: Active accessible product with manageable setup for its intended user.
- 9–10: Straightforward self-service access and setup, with unusually few adoption obstacles.
Value and cost clarity: How attractive and understandable is the cost model for the documented use?
- 1–2: No current purchasable or usable offer; historical prices cannot support a purchase.
- 3–4: Material price, entitlement, license or availability uncertainty limits budgeting.
- 5–6: Plausible value with custom pricing, significant setup costs or incomplete selected-plan terms.
- 7–8: Useful scope with clear entry pricing/allowances or accessible source, while accounting for running costs.
- 9–10: Exceptionally accessible and clear cost model for substantial useful scope; never assume free compute.
Integration options: How useful and extensible are the verified user-facing connections for the intended workflow?
- 1–2: No current user-facing connection verified, or former connections are unavailable.
- 3–4: Inputs/exports or one focused connection; internal dependencies are not native connectors.
- 5–6: Useful API, configurable tools or several relevant connections, with limited verified breadth.
- 7–8: Broad relevant connections or an extensible documented API/MCP/tool ecosystem.
- 9–10: Extensive documented ecosystem with multiple connection mechanisms and strong task relevance.
