2026 roundup
AI agent marketplace alternatives
A fair look at the major AI agent marketplaces in 2026 — where to buy, where to discover, where to list. Each entry includes the catch as well as the upside.
How to read this list
Eight marketplaces. We list Rent an Agent first but acknowledge where it isn't the right fit — for ChatGPT-only buyers, enterprise procurement, or anyone who just wants to browse, other entries are better. Use this page as a decision tree, not a rank.
The marketplaces, ranked
Order reflects fit for the typical Rent an Agent reader (individual buyers and indie builders), not raw popularity. Enterprise marketplaces (AWS, Google Cloud) rank lower not because they are worse but because they target a different buyer.
- 1
Rent an Agent
This siteCurated marketplace of downloadable AI agent skills (SKILL.md-format files, persona files, system prompts). Every listing hand-reviewed; runs in any LLM tool you already pay for.
- Best for
- Buyers who want portability, ownership, and a hand-picked catalog instead of an open dump. Builders who want a higher revenue share (starting 15%) and curated distribution.
- The catch
- Tiny catalog today (one live agent as of 2026-05). Curation means slow growth on the supply side.
- Pricing
- Per agent, $49–$999 one-time (Digital Elon: $99). No subscription, no usage limits.
- 2
ChatGPT GPT Store
chatgpt.com/gptsOpenAI's official catalog of hosted Custom GPTs. ~3M+ GPTs available, only runnable inside ChatGPT.
- Best for
- Buyers who live entirely inside ChatGPT and want the biggest available catalog. Builders who want effortless distribution to ChatGPT Plus users.
- The catch
- Open submission means widely variable quality. Locked to ChatGPT only — no Claude, no Cursor, no offline use. Limited revenue program for builders.
- Pricing
- Bundled in ChatGPT Plus ($20/month) for buyers. Builder revenue program varies by region; not comparable to a percentage of sale.
- 3
Agent.ai
agent.aiHubSpot-affiliated AI agent platform with a directory of pre-built agents plus build tools. Strong focus on business-workflow automation.
- Best for
- Businesses already in the HubSpot ecosystem, or buyers looking for ready-to-deploy workflow agents (sales prospecting, lead enrichment, content ops).
- The catch
- Platform-locked — agents run on Agent.ai's infrastructure. Less suited for individuals who want files they own.
- Pricing
- Mixed — free directory plus paid agent runs. Business-tier pricing not publicly fixed.
- 4
AI Agent Store
aiagentstore.aiIndependent marketplace and directory of AI agents. Builders can list their own; buyers can browse hundreds of options.
- Best for
- Discovery — broad browsing of what's in the AI agent ecosystem across categories.
- The catch
- Open submission, minimal curation. Discovery surface, not a delivery mechanism — actual purchase / use happens on the builder's site.
- Pricing
- Free to browse. Per-agent pricing varies by listing.
- 5
AI Agents Directory
aiagentsdirectory.comCurated directory of ~1,300 AI agents, frameworks, and tools. Discovery-focused; agents are cataloged, not sold.
- Best for
- Researching what's available in the AI agent ecosystem. Practitioners scanning for automation tools across workflow optimization, customer service, data analysis.
- The catch
- Pure directory — no transactions, no built-in purchase or download. Use it to discover, then go elsewhere to buy.
- Pricing
- Free.
- 6
AWS Marketplace (AI Agents)
aws.amazon.com/marketplaceEnterprise marketplace of AI agents and tools from AWS Partner Network members. Vendor-validated, AWS-deployable.
- Best for
- Enterprise procurement teams. Companies that need an agent integrated with existing AWS infrastructure, compliance, and security review.
- The catch
- Enterprise-only friction. Per-agent setup is heavyweight. Not realistic for individual buyers or solo builders.
- Pricing
- Per-agent, vendor-set. Procurement happens through AWS billing.
- 7
Google Cloud AI Agent Marketplace
cloud.google.comMarketplace of pre-vetted AI agents validated to integrate with Gemini Enterprise. Built for Google Cloud customers.
- Best for
- Organizations standardized on Google Cloud + Gemini Enterprise. Procurement through GCP billing.
- The catch
- Locked into Google Cloud ecosystem. Most agents require existing GCP infrastructure. Not consumer-facing.
- Pricing
- Per-agent, vendor-set. Procurement through Google Cloud billing.
- 8
ProBazaar
probazaar.aiUnified marketplace of 5,000+ ready-to-deploy AI assets including prompts, workflows, agents, and apps. Multi-model (ChatGPT, Claude, Midjourney, etc.).
- Best for
- Buyers who want a large catalog covering more than just agents — prompts, workflows, n8n flows alongside agents.
- The catch
- Quality varies because the catalog is broad and open. Less curation than a hand-reviewed marketplace.
- Pricing
- Per-asset; varies widely by listing.
