Kernel - Pros & Cons
Pros
- ✓Eliminates the six-month infra project of running a production headless-Chrome pool
- ✓Works with existing Playwright / Puppeteer code — no SDK lock-in
- ✓Captcha + residential proxy handling meaningfully improves scraping success rates
- ✓Replay UI is a huge productivity win for debugging agent trajectories
- ✓Free hobby tier makes prototyping cheap
Cons
- ✗Usage-based pricing scales with browser-minutes — long-running research agents can get expensive fast
- ✗Managed service (no self-host) — regulated customers may need to wait for VPC deploy
- ✗Newer than Browserbase and Steel; smaller community for Stack Overflow-style questions
- ✗Captcha solving still probabilistic — some highly protected targets will fail
AI Agent Marketplaces - Pros & Cons
Pros
- ✓AI Agent Store provides vendor-neutral discovery at $0 cost to browse, letting buyers compare agents listed across major enterprise marketplaces and independent developers in one place rather than searching each storefront separately
- ✓Deployment of pre-built agents compresses from the multi-month timelines typical of custom development to days or weeks via pre-integrated marketplace agents
- ✓Cross-platform visibility aims to surface agents that buyers miss when searching only within their primary cloud vendor's marketplace, expanding the evaluation set across ServiceNow, Microsoft, AWS, and Salesforce ecosystems simultaneously
- ✓Microsoft agents span Teams, SharePoint, Outlook, and Dynamics 365 natively, and AWS agents leverage Bedrock and SageMaker infrastructure — AI Agent Store aims to surface both alongside independent options
- ✓Vertical categories surface industry-specific agents from platforms like Salesforce AgentForce for CRM and ServiceNow for ITSM, reducing search time for domain-tuned options across multiple industry verticals
- ✓The directory model creates no vendor lock-in at the discovery layer — buyers can switch research tools without migration cost, unlike switching between enterprise agent platforms
Cons
- ✗Agent quality varies significantly — enterprise platforms vet rigorously, but independent listings rely on community ratings that can be unreliable for niche or newly listed agents
- ✗Customization of pre-built agents is inherently limited compared to custom development; actual coverage of specialized workflow requirements varies by agent and vendor, and buyers should evaluate fit on a case-by-case basis
- ✗Platform lock-in is material once agents are deployed: migrating away from ServiceNow or Microsoft-tied agents often means re-doing integrations built over months
- ✗The directory aggregates information provided by vendors, so listing details (pricing, features, performance claims) should be verified directly with the agent developer before purchasing
- ✗Ongoing agent quality depends on third-party developer maintenance, which can stall if the vendor deprioritizes the listing
