Which one is for you
Pick Fetch.ai Agentverse if
- Fits if you want your agent listed and found inside the Fetch.ai ecosystem
- Works for developers who already build with LangGraph or CrewAI
Look elsewhere if
- Tight if you stay free: quotas cap messages, storage and hosted compute
- Skip it if you need a published price, because the paid plans were not readable
- Watch out: free users must log in every 30 days to keep agent mailboxes active
- Watch out: subscriptions and deep links for paid agents are marked coming soon
Pick LangGraph if
- Fits if you write Python or JavaScript and want control over each agent step
- Works for teams that already use LangChain or LangSmith
Look elsewhere if
- Not for you if you want a visual builder, because the framework itself has none
- Pricey if you deploy on LangChain's servers, which needs Plus at $39 a seat a month
- Watch out: traces, Agent Server compute and sandboxes are metered in LSUs at $1 each past the allowances
- Tight if you need history, since base traces are kept 14 days and 180-day traces cost extra

|---|---|---|
| Value for money | CWe could not read the Basic, Premium and Enterprise prices, since the docs show them as images, so it sits mid-pack by default. | CThe library is free, but deploying on LangChain's infrastructure needs LangSmith Plus at $39 a seat, above the category's middle of $25, with usage billed in LSUs. |

Worth knowing
Fetch.ai Agentverse
- Subscription prices were not readable: the docs show the Basic, Premium and Enterprise plans only as images, and the Agentverse site answered with a bot check.
- Usage is capped by quotas on messages, storage and hosted compute time, whatever the plan.
- Paid access for agents, such as subscriptions or deep links, is listed in the docs as coming soon.
- Fetch.ai also runs a consumer assistant, ASI:One, and a business agent product, which are separate from Agentverse.
LangGraph

- Beyond the included allowances, traces, Agent Server compute and sandboxes are metered in LangSmith units (1 LSU = $1).
- Base traces are kept 14 days; 180-day extended traces cost extra.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
