Alternatives to Pctx
30 tools that compete with or replace Pctx. Ranked by direct product-type match — not generic category overlap.
What is the best Pctx alternative?
The best Pctx alternative today is Mem0 because it is a safe bet on our live viability checks, it has the widest real-user coverage of these options and AI engines read it more than any other option here; it also has a free tier.
Ranked on live viability checks, real-user mentions and how often AI engines read each tool — never pay-for-placement.

pumaDB
Hosted MCP and REST memory that keeps AI agent context consistent across ChatGPT, Claude, Codex, and your own agents.
DataGrout
DataGrout is an operating layer for production AI agents: persistent memory, real-time cost control, and cryptographic receipts for every action.

Self-hosted layer that gives your AI coding agents shared memory, managed MCP tools, and cross-model audit.
Signetai
Local-first agent memory and secrets layer that gives Claude Code, Codex, and OpenCode one shared context on your own machine.
Memtrace Public
Memtrace is a shared code-map memory layer that keeps multiple AI coding agents reading one live structural map of your repository.
Powermem
Open-source, self-hosted memory layer that gives AI agents persistent recall via hybrid retrieval.
Mentedb
Long-term memory for AI agents: one process_turn call stores each turn and returns the memories your next prompt needs.
Archil
Archil mounts S3, GCS, or NFS live as a POSIX filesystem so AI agents get durable disks, sandboxes, and serverless tool calls.
Alive
ALIVE is a free, MIT-licensed local context manager that gives Claude Code durable, file-based project memory across sessions.
Dedalus Labs
Dedalus Labs boots persistent Linux VMs for AI agents in under 50ms, billed per second with idle time free.
Distill
Distill trims LLM agent context with deterministic semantic dedup and compression in ~12ms — no LLM calls, same input every time.
Omnara
Omnara is a stateful, open-source agent API for deploying durable AI agents on any model, machine, or cloud.
MemoryLake
MemoryLake is portable AI memory for ChatGPT, Claude, Codex and Gemini — encrypted, exportable, and shared across every agent you run.
Statewave
Open-source, self-hosted AI agent memory runtime with governance policies and tamper-evident audit receipts.
Automem
Open-source MCP memory layer that gives AI agents a graph plus vector store so recall carries relationships, not just similar text.
MemU
memU gives Codex, Claude, Cursor and other agents one shared, inspectable memory layer with source-linked recall.
MemOS
MemOS gives AI agents persistent long-term memory through a cloud API or a fully local runtime.
Memori
Memori is an LLM-agnostic agent memory gateway that turns every execution trace into persistent, governed memory and procedural recall.
Agentbox Sdk
Run AI coding agents in isolated cloud sandboxes — locally on your Mac or delegated from Slack, Linear, and GitHub.
Memoryport
Memoryport is a local-first memory layer that gives Claude Code, Cursor, Ollama and OpenAI persistent context across every session.
Shodh Memory
Zero-LLM persistent agent memory — Hebbian learning and decay curves in a single 30MB Rust binary.
npm i -g hotcell
Self-hosted AI agent sandboxes with Docker, Firecracker or Apple VZ — your real API keys never enter the sandbox
Mempalace
Open-source local-first AI memory that stores every conversation verbatim in a method-of-loci palace on your machine.
TrueMemory
TrueMemory gives CLI coding agents persistent local memory recall in about 55ms — one SQLite file, zero cloud.
Unbody
Unbody is an open-source AI-native backend with a self-evolving memory layer for agentic RAG apps.
EverMemOS
EverMemOS gives AI agents persistent, self-evolving memory across sessions, platforms, and teams.
Hermes Webui
Self-hosted AI agent with a browser UI, markdown memory on disk, and a cron scheduler that runs while you're offline.
Caura Memclaw
Governed shared memory for AI agent fleets — scoped writes, keystone policies and a per-recall audit trail.

How this page is made: a human editor decides what is published. Drafts are proposed by a mixture of models (Claude Opus 4.5, GPT Codex and DeepSeek’s strongest models) working from our own verified data — live site checks, current pricing and the public sentiment we gather from Reddit, Product Hunt, G2 and community forums — and the editor keeps, corrects or strikes each line. Nothing here is pay-for-placement. Read the full methodology.
