An open-source, self-hosted memory layer that links related facts across Claude, ChatGPT, Cursor and Codex via MCP. Built for developers comfortable self-hosting on Cloudflare, not a plug-and-play tool.

Open sourceSelf-hosted
What to know
How it works
A memory layer that remembers projects, people, decisions and preferences across Claude, ChatGPT, Cursor, Codex and any MCP client, automatically linking related memories and following those connections during recall.
What's different
Open source and self-hosted in your own Cloudflare account, and distinguishes settled decisions from drafts/stale context.
Best for
Developers comfortable self-hosting on Cloudflare who want a shared memory layer across multiple AI tools.

A local gateway that lets every AI coding client share one set of MCP server connections instead of configuring each tool separately, cutting how many tools your agent has to load.

FreeNo sign-upWorks offlineOpen source
What to know
How it works
A local-first, open-source gateway. You set up and authenticate each MCP server once, and every connected AI client — Claude, Cursor, VS Code, Codex — shares that same connection instead of you configuring it per tool.
What's different
Claims up to 91% less tool-token overhead by giving an agent a handful of meta-tools instead of loading hundreds of individual tool definitions; API keys stay in the OS keychain.
Pricing
Free, open source, no sign-up.
Best for
Developers running multiple AI coding clients against the same set of MCP servers who don't want to re-authenticate each one separately.
Watch out
The '91% overhead cut' figure is the product's own claim; we haven't independently benchmarked it.

What's different
Never reads your code, only detects when session files change; open source with an opt-in leaderboard.
Pricing
Free.
Best for
Developers who want to show off or track which AI coding tool they're using on Discord.

An open-source framework that turns your existing AI coding agent into a persistent virtual cofounder that remembers your venture across sessions, for solo technical founders.

Open source
What to know
How it works
An open-source install turns an existing AI coding agent — Claude Code, Cursor, Antigravity, Gemini CLI, GitHub Copilot — into a persistent virtual cofounder: one line installs it, `shotgun-init` injects it into a folder or codebase, and after a one-time onboarding it remembers your venture, builds your product, and keeps your data organized.
What's different
Open-source and works on top of whatever AI agent you already use, rather than being its own separate assistant.
Best for
Solo technical founders building without a human cofounder.

An open-source local MCP server that gives AI coding assistants like Claude Code, Cursor and Copilot a live map of your AWS setup, database schemas and infrastructure-as-code.

Works offlineOpen source
What to know
How it works
An open-source MCP server that gives AI coding assistants like Claude Code, Cursor, and Copilot a live, read-only map of your AWS services, database schemas, and infrastructure-as-code, including exact partition keys, Lambda event shapes, and misconfiguration warnings.
What's different
One command, zero config, runs 100% locally with no data leaving your machine.
Pricing
Open source.
Best for
Developers using AI coding assistants who want those assistants to understand their real AWS infrastructure instead of guessing.
Watch out
Read-only and local-only by design, but it does connect to your live AWS account to build its map.

An open-source API for programmatically posting to Bluesky, X, Pinterest (and soon Meta and LinkedIn) in one call, with a native MCP server for Claude and Cursor. Built for developers and AI agents automating social posting.

Domain registered 3 months ago

Open source
What to know
How it works
A single API call publishes a post to Bluesky, X, and Pinterest, with Meta and LinkedIn in review; it runs preflight checks against roughly 80 platform-specific rules before posting and includes a native MCP server for Claude, Cursor, and Claude Code.
What's different
Open source (Apache 2.0), with pinned API versions, default idempotency, and transparent error envelopes.
Best for
Developers and AI agents that need to automate posting to multiple social platforms from code.

A single API call returns live, cryptographically signed data across 87 sources so AI agents and software can verify what they're consuming — a developer-facing trust layer, not a consumer app.

No sign-upOpen source
What to know
How it works
A single keyless API call returns structured JSON for 87 live tools across 19 verticals; each datapoint carries its source, licence, timestamp and an Ed25519 signature, optionally Bitcoin-anchored.
What's different
Data is cryptographically verifiable rather than just scraped and cited, and it works without signup or an API key via an MCP endpoint or batch POST.
Best for
Developers building AI agents or software that need to independently verify the live data they consume.

Turns your Android phone into a self-hosted MCP server so AI assistants like Claude, Cursor or Perplexity can pull your personal memory without sending data to the cloud. Aimed at developers already using MCP-compatible tools.

Works offlineData stays with youOpen sourceNo subscription
What to know
How it works
Turns an Android phone into a self-hosted MCP (Model Context Protocol) server by installing a Python MCP server inside Termux, with a secure tunnel giving the phone a stable public HTTPS URL that AI clients like Claude, Cursor or Perplexity can connect to for persistent memory.
What's different
Data is stored locally on the user's own phone instead of a vendor's cloud, with no subscription or vendor lock-in.
Pricing
No subscription.
Best for
Developers already using MCP-compatible AI tools who want to own their memory data instead of storing it in the cloud.
Watch out
Relies on a relay tunnel (relay.memplato.com) and requires Termux running on the phone, with a watchdog to restart the server if the phone reboots or Termux closes.

A shared memory and governance layer so multiple AI agents can recall what the others learned - backend infrastructure for developers building agent fleets, not an end-user app.

Domain registered 4 months ago

Open source
What to know
How it works
A shared memory layer for multi-agent AI fleets: agents write what they learn and recall what the fleet knows, with mandatory governance rules (Keystones) enforced at session start.
What's different
Detects contradictions between memories via RDF triples plus LLM analysis, and deduplicates near-duplicate memories into atomic facts with provenance via its Crystallizer.
Best for
Developers building multi-agent AI systems who need cross-agent recall without knowledge silos or leaks.
