People search for a Mem0 alternative for two very different reasons. Some are building an app and want it to remember its users. Others use Claude Code, Cursor or Codex every day and want the agent to stop forgetting what it worked out last week. Mem0 now serves both, and the best alternative depends on which one you are.
We make one of the alternatives, FixMyPrompt, so read this with that in mind. We have tried to be fair about where Mem0 is the better choice.
What Mem0 is
Mem0 is a memory layer for AI agents and apps. It is open source under the Apache 2.0 license, with a large following on GitHub, and it also runs as a hosted platform. You send it conversations or text, it extracts memories, and your app retrieves the relevant ones later.
For coding agents, Mem0 offers a hosted MCP server and a Claude Code plugin, marketed as OpenMemory. It auto-captures your coding preferences, patterns and setup as you work, and its memories are scoped to a user_id, so the same store is shared by Claude Code, Cursor and Codex.
Mem0 pricing, from its pricing page as of November 2026, has two plans:
| Plan | Price | What you get |
|---|---|---|
| Free | $0 | 10,000 adds and 1,000 retrievals a month for the first 30 days with model calls on Mem0, then 50,000 adds and 10,000 retrievals a month with your own LLM key. Usage billing past that, with a cap you set |
| Custom | Talk to sales | Limits set to your volume, plus graph memory, user profiles, memory consolidation, SSO, audit logs, SLA and on-prem deployment |
If you are building an app
If your users are the ones being remembered, such as a support bot that recalls a customer's history or a companion app that knows someone's preferences, you want a general memory layer. Mem0 is a strong pick, and so are its direct alternatives:
- Zep, with its open-source Graphiti library, built around a temporal knowledge graph. A good fit when facts change over time and you need to know what was true when.
- Letta, formerly MemGPT, open source, where the agent manages its own memory tiers.
- Supermemory, a hosted memory and retrieval API with a small surface.
Each has its own benchmarks and its own claims. Test two or three on your real data before you choose.
FixMyPrompt is not one of these. It has no SDK for storing your end users' memories, and we would not recommend it for that.
If you want your coding agent to remember
This is where the comparison gets interesting, because Mem0 and FixMyPrompt solve it in opposite ways.
Mem0 captures automatically. As you work, it pulls out facts and preferences, such as "uses TypeScript" or "prefers pnpm", and feeds the relevant ones back to the agent. You do little and get a lot of small context.
FixMyPrompt saves what you tell it to save. When Claude Code finally works something out, such as why the staging deploy fails on a clean checkout, you ask it to save that. What gets stored is a procedure: the steps, the commands, how to check it worked and what not to do. FixMyPrompt checks it for passwords, keys and other secrets before anything is stored. Next time the same task comes up, the agent finds that memory and follows it instead of spending another hour.
The difference shows up in what you get back. Automatic capture is good at preferences and facts. A deliberate save is better at the hard-won fix, the thing that took real time to find and would take just as long to find again. Our Claude Code memory guide goes into why the built-in memory alone does not keep these.
| Mem0 (coding agents) | FixMyPrompt Memories | |
|---|---|---|
| What gets saved | Facts and preferences, captured as you work | Procedures you ask it to save: steps, checks, what not to do |
| Who decides | Mem0 extracts automatically | You. Nothing is saved until you say so |
| Tools | Claude Code, Cursor, Codex and other MCP clients | Claude Code, Codex and Cursor |
| Versions | Update or delete a memory | Versions with undo and an in-use mark |
| How the agent uses it | Retrieves relevant memories through MCP | Searches memories through MCP. In Claude Code, a named memory also runs as a slash command |
| Open source | Yes, Apache 2.0, and self-hostable | No |
| Price | Free with limits, then usage billing or a custom plan | Pro $19 a month, 7-day trial |
If you want something that runs on your own servers, Mem0's open-source version is the clear choice. FixMyPrompt is hosted only.
For teams
Both can give a whole team the same memory, but they handle trust differently.
On FixMyPrompt's Biz plan, memories are shared across the company, so one developer's fix reaches everyone's Claude Code, Codex and Cursor. Admins decide what is shared and whether changes to a shared memory need their approval. That matters when the memory is a deploy procedure: you want a person to sign off before a new version reaches twenty developers' agents. Biz is $25 a seat a month with a 2-seat minimum and a 7-day trial.
Mem0's SSO and audit logs are on its Custom plan, so a team setup there starts with a sales conversation. If you are on the Claude Team plan already, our guide to the Claude Code Team plan covers what it shares and what it leaves on each machine.
Which one to pick
- Building an app that remembers its users: Mem0, Zep, Letta or Supermemory. Not FixMyPrompt.
- Want to self-host: Mem0's open-source version.
- Want your coding agent to pick up preferences without effort: Mem0's coding-agent setup does this well.
- Want your coding agent, and your team's, to keep the fixes that took hours: that is what FixMyPrompt Memories is built for.
Plenty of developers will want both kinds of memory. They do not conflict: one keeps the small facts, the other keeps the procedures. If you are starting from scratch, the cheapest first step is still a good CLAUDE.md, and the free CLAUDE.md checker shows what yours costs every session and which guardrails it never mentions.
