Kosmos vs OneQuery
vs
Introduction
Kosmos, from Edison Scientific, supports scientific research through connected literature and data analysis. OneQuery is an experimental Python browser agent that turns a task and optional output schema into structured web data. These ratings are subjective editorial opinions about each product’s stated purpose, not measured benchmarks.
Overview
OneQuery
OneQuery is an experimental Python browser agent that turns a task and optional output schema into structured web data. The repository documents iterative browser interaction and structured Pydantic output, plus an optional FastAPI scraping endpoint. Tests and documentation remain work in progress.
Kosmos
Kosmos, from Edison Scientific, supports scientific research through connected literature and data analysis. Research branches combine literature, data analysis and hypothesis development for scientific teams.
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: 2026-10-27. 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.
Metrics Comparison
Documented capability
Kosmos: 8/10
Evidence confidence: medium
Research branches combine literature, data analysis and hypothesis development for scientific teams.
OneQuery: 5/10
Evidence confidence: medium
The repository documents iterative browser interaction and structured Pydantic output, plus an optional FastAPI scraping endpoint. Tests and documentation remain work in progress.
Choose by the task you need to accomplish; different workflows are not interchangeable.
Ease of adoption
Kosmos: 5/10
Evidence confidence: medium
The current enterprise offer involves guided deployment and domain-specific setup rather than a generic no-code agent builder.
OneQuery: 4/10
Evidence confidence: medium
Setup requires Python, Playwright, a local OmniParser service and configured model credentials. The former hosted domain is unavailable; use the repository route.
Account for current access, configuration and the human work required.
Value and cost clarity
Kosmos: 5/10
Evidence confidence: medium
Current enterprise terms are quoted; do not transfer prices or capabilities from unrelated Kosmos repositories.
OneQuery: 6/10
Evidence confidence: medium
MIT source is accessible, but model usage, hosting and engineering maintenance remain your costs. No current hosted subscription is established.
Compare subscription, usage, implementation and required-service costs together.
Integration options
Kosmos: 6/10
Evidence confidence: medium
The vendor describes Slack, Teams and email workflows plus scoped enterprise data and on-premises options.
OneQuery: 5/10
Evidence confidence: medium
The Python interface and optional /scrape API can feed custom workflows. Browser and parser dependencies are not ready-made CRM or warehouse connectors.
Check that the connections you need are included in the actual plan.
Conclusions
Consider Edison’s Kosmos for specialist R&D collaboration with researchers responsible for experiments and scientific conclusions. Consider OneQuery for developer-led browser extraction experiments, with time to maintain the local stack and validate the returned data.
