Which one is for you
Pick Dosu if
- Fits if your team wants docs that follow code changes in GitHub or GitLab
- Works for open-source maintainers, since public repositories are free
Look elsewhere if
- Tight if your code is private: the free plan covers public repositories only
- Pricey if you pay monthly, because the $16 price is the yearly rate and $192 is charged upfront
- Skip it if you rely on Linear, which is an Enterprise integration
- Watch out: extra credits can be added on Pro but their price is not published
- Watch out: the Pro trial length is not stated
Pick Letta if
- Fits if you are a developer who wants agents that keep their memory between runs
- Works for people who already pay for a coding plan and can bring that key
Look elsewhere if
- Tight if you stay free, because there is no included model usage and 3 agents is the cap
- Pricey if you code heavily, as the pricing page says $100 to $200 a month or more of usage
- Watch out: server tool time is billed at $0.00015 a second against your credits
- Watch out: more than one person needs Teams Pro, since Pro covers a single user

- Observability and analytics
- Pro adds views of what the team is working on and what Dosu's contribution has been.
Letta

- An open-source harness installed with npm for coding agents, personal assistants and agents that work on local files, with skills and schedules.
- Agent SDK and app server

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.
