Side-by-side comparison of two listed AI Agents tools — real listing data only, no paid placement.
On record, they differ in: pricing (MemGPT Free vs Ona Paid); unique tags (MemGPT 2: #documentation #migration vs Ona 3: #cloud #automation #security); category rank (MemGPT #40 vs Ona not in top 50). Same category (AI Agents). Listing facts only — not a recommendation.
AI agent docs migrated to Letta
MemGPT is an AI agent framework whose documentation has been relocated to Letta. The original MemGPT docs now redirect users to docs.letta.com, with an index of pages available in Markdown and OpenAPI formats. This change reflects the migration of the project to the Letta platform.

Run background agents in the cloud
Ona is a platform for running background agents, enabling teams to deploy AI software engineers in the cloud. It supports end-to-end execution from task to pull request, with automations triggered by PRs, schedules, or webhooks. Agents operate in connected cloud environments with kernel-level security, audit trails, and scoped credentials, and can run in your VPC for complete network control.
