Comparisons, pricing deep-dives, and engineering notes on building persistent memory for coding agents.
Keep breaking changes, verified flags, and workarounds in project memory so each version bump starts with recall instead of re-research.
Keep project context when you change tools: one shared memory, the same key everywhere, plus an import and recall check.
A four-part template turns team agreements into memories every agent retrieves — rule, scope, example, and exception in one place.
A multi-week refactor workflow: store constraints and decisions once in agent memory, recall them every session, and delete notes as modules land.
One project per repo, one key per agent, scoped tokens for automation — plus a wrong-key test that proves the isolation holds.
Give each new hire's agent the team's project memory on day one, run a first-week write-back loop, and audit stale facts before they ship.
Point Claude Code, Codex, and OpenCode at a single project key, prove recall across tools, and keep the shared memory accurate.
Imports, CI runs, and refactors make memory usage spike. Here is the flat-quota math for a 200,000-add month, plus counting rules.
The $0 Hobby tier gives solo developers 10K adds and 1K retrieves with unlimited projects. Here is how far that stretches and when $12 Starter makes sense.
How Audaxic counts memory operations, what the five tiers cover, and how to estimate your month from session habits.
Build a fix library your agent searches before debugging — one entry per recurring pattern, with dedupe and update habits.
A feature-lifecycle playbook: atomic decision notes, a recall-first restart checklist, and weekly cleanup that survives compaction and new terminals.
Same quotas, same month: how $12, $50 and $125 compare with $19, $79 and $249, plus the $0 Hobby tier and flat monthly billing.
Store and search project memories with curl in minutes: five endpoints, version pinning, and 429 handling for any language or CI job.
End each session with a three-sentence note in project memory. The next engineer recalls it before reading code.
Self-hosting means running vectors, extraction, keys, backups, and pages. Here is an honest comparison plus the managed tiers and a decision checklist.
Give every new repo a project memory on day one: connect agents, import history, seed conventions, and prove recall.
Swap two env vars, run five endpoint checks, and import only the memories worth keeping.
Store each outage lesson once, recall it next time. A practical debugging workflow with search, update, and cleanup.
Give your PR reviewer a memory: style rules, past decisions, and recurring mistakes your coding agents already know.
Start work in Claude Code, finish it in Codex. Both plugins read the same project memory, so the second agent starts informed.
One remote endpoint gives any MCP client persistent memory. Create a key, paste one config entry, and confirm recall in a fresh chat.
One shared key for the whole team is a context fix with an access problem. Group projects into workspaces and give every agent its own key instead.
Install the plugin, connect a project key, and keep conventions across /clear and restarts. Import old OpenCode sessions in the same setup.
An add request is counted per memory extracted, so budgets move with extraction volume. Here is the per-tier math plus worked solo-dev and five-person examples.
Cursor has no memory plugin. Connect the remote MCP server with one config entry and the agent keeps project facts across new sessions.
A bigger window holds more history in one session and still starts blank the next morning. Here is the line between working state and durable memory.
Codex CLI forgets your project every time you open a terminal. Install the plugin to keep context across restarts and share one memory with your other agents.
Claude Desktop and Windsurf both speak MCP. Point them at one remote memory server and your desktop agents keep project facts across conversations.
One install command and one project key give Claude Code a memory layer that survives compaction, /clear, and new terminals.
Projects now live in workspaces, and scoped auth tokens unlock programmatic management. Your projects moved to Default — nothing to do.
Agents don't learn — but with persistent memory, they stop repeating mistakes. Experience matures agents the way it matures people.
Months of chat history, searchable in minutes. One install, one dry-run, one import — correct timestamps, safe to re-run.
Claude Code forgets your project decisions after compaction? A persistent memory layer extracts facts while you work and recalls them after — so the next agent picks up where the last left off.
Told it to use bun three times and it still runs npm? Your agent isn't forgetful — it's stateless. One shared memory layer makes conventions stick across Claude Code, Codex, OpenCode.
Mem0 charges $19/$79/$249 for 50K/200K/500K adds. Audaxic gives the same quotas for $12/$50/$125 — up to 50% cheaper, flat monthly, no overages. Mem0-like API, easy to adopt.
Head-to-head on free tier, pricing, graph memory, MCP, and infra. Mem0 Pro-only graph, Zep temporal memory, SuperMemory usage-based, Audaxic cheapest flat pricing on Cloudflare edge.
