Which one is for you
Pick Gumloop if
- Fits if you want people who aren't engineers to build their own agents
- Works for teams that would rather pay one flat price than count seats
Look elsewhere if
- Not for you if you want to try it without a card, as the 14-day trial needs one and then bills you
- Pricey if you're one person, at $37 a month where a team would be splitting the same bill
- Skip it if you need audit logs, access roles, SAML or data exports, which are Enterprise only
- Watch out: credits don't roll over, agents stop at 20,000 unless pay-as-you-go is on, and there's an 8% fee, 16% on your own keys
- Skip it if you want a phone or desktop app, as Gumloop is a web app used through Slack, Teams and Gmail
Pick Stack AI if
- Fits if you want to build one or two agents and try them free
- Makes sense if you plan to ask for an enterprise deployment later
Look elsewhere if
- Tight if you work in a team, as Free is 1 seat and 2 projects
- Not for you if you want a self-serve paid plan, because none is published
- Watch out: SSO, access control, VPC and on-prem are Enterprise only
- Watch out: the homepage says Asana acquires StackAI, so ownership and plans may change
How we grade them
| 2.0GPAGumloopFair | 2.2GPAStack AIFair | |
|---|---|---|
| Value for money | DThe only self-serve plan is $37 a month, well above the $23 or so that agent tools here start at, with 20,000 credits that don't roll over and an 8% orchestration fee on usage, or 16% on your own model keys. Unlimited seats bring the cost per head down for a team; one person pays the full $37. | COnly Free and a custom Enterprise plan are listed, so there is no published paid price to set against the category. |
| Free plan and trial | DNo free plan at all. New accounts get one 14-day Pro trial, it asks for a card, and it turns into a paid subscription unless you cancel. Put a reminder in your calendar. | CFree allows 500 runs a month, 2 projects and 1 seat, with community support on Discord. You will hit those caps. |
| Features | BIt covers the job: agents across more than 300 connectors and your shared company knowledge, on 35-plus models or your own keys, started by app triggers, schedules or a REST API, with reusable skills that sync to GitHub and four levels of sharing. Access roles, audit logs and exports are Enterprise only. | CA flow builder, knowledge bases and data loaders, and several ways to ship an agent. SSO, VPC, on-prem and BAA sit on Enterprise only. |
| Ease of use | CIt's pitched at non-engineers building their own agents, and a finished one is used by @mentioning it in Slack. Getting there means connecting tools, building the agent and watching a shared credit pool, and there's no rating on record. | CNo store rating on record, and building an agent means setting up flows and data. |
| Platforms and integrations | BA web app, with agents usable in Slack, Microsoft Teams and Gmail, more than 300 connectors and a REST API. No phone or desktop app on the listing. | BWeb plus a browser extension, with Slack, Google Drive and Notion listed. |

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.
