ContextForge is persistent, searchable memory for AI coding agents โ€” built on the Model Context Protocol (MCP).

Your AI assistant forgets everything when the session ends. ContextForge fixes that: save architectural decisions, naming conventions, and debugging context once, and any MCP client recalls it later with semantic search โ€” across sessions and across projects.

Works with: Claude Code, Claude Desktop, Cursor, GitHub Copilot, ChatGPT, and Windsurf.

    Relying on an external service for port forwarding can be a disadvantage if the service experiences issues or discontinues.
  • Configuration Limits
    Advanced users might find the configuration options somewhat limited compared to setting up port forwarding manually on their own networks.

Analysis of Portmap.io

Overall verdict

  • Portmap.io is generally considered a good tool for its ease of use, reliability, and features such as SSL support and a user-friendly interface. However, users should be aware of potential security risks when exposing local services to the public internet.

Why this product is good

  • Portmap.io is a popular choice for users looking to expose local servers to the internet without dealing with complex network configurations like port forwarding. It provides a straightforward solution for developers wanting to test, share, or access services remotely.

Recommended for

    Developers, system administrators, and hobbyists who need to access local services remotely or those testing webhooks and other remote internet applications.

Analysis of ContextForge.dev

Overall verdict

  • I don't have verified, specific information about ContextForge.dev, so I can't confirm its quality, features, or reputation with confidence. It may be a legitimate niche developer tool, but you should independently verify it before relying on it.

Why this product is good

  • I have no reliable data on this specific domain's product, pricing, reviews, or track record
  • The name suggests it may relate to 'context' management for AI/LLM development, but this is speculative
  • Unverified tools can carry risks around data security, support quality, and long-term viability
  • Small or new dev tool sites can be legitimate but lack the review history needed for a confident assessment

Recommended for

  • Users who independently research and verify the site's legitimacy first
  • Developers curious about niche AI/context-management tools who are comfortable testing new services
  • Not recommended for critical production use without due diligence, given the lack of verifiable information

Questions & Answers

As answered by people managing Portmap.io and ContextForge.dev.

What makes your product unique?

ContextForge.dev's answer:

ContextForge is memory that lives at the MCP layer, so it works across every AI coding agent at once โ€” Claude Code, Cursor, GitHub Copilot, ChatGPT, and Windsurf โ€” not just one. Save a decision once and any client recalls it later with semantic search. It goes beyond a note store: automatic git sync turns your commits and PRs into searchable knowledge, plus task tracking, snapshots, and team sharing โ€” all through a single MCP server you add with one command.

Why should a person choose your product over its competitors?

ContextForge.dev's answer:

Most memory tools are tied to a single agent or are just a key-value store. ContextForge is MCP-native, so it's portable across all your AI tools; it adds git sync so your codebase history becomes searchable context automatically; and it includes team features (shared spaces, collaborators) that solo-memory tools lack. Setup is one command, there's a genuine free-forever tier with no credit card, and paid plans start at just $9/month.

How would you describe the primary audience of your product?

ContextForge.dev's answer:

Software developers and engineering teams who use AI coding assistants โ€” Claude Code, Cursor, GitHub Copilot, ChatGPT, Windsurf โ€” and are tired of re-explaining their project, architecture, and conventions every session. It fits solo developers working across multiple projects as well as small teams that need shared, persistent context.

What's the story behind your product?

ContextForge.dev's answer:

ContextForge was born from a simple frustration: AI coding agents forget everything the moment a session ends. Every new conversation meant re-explaining the same architecture, naming conventions, and past decisions. ContextForge was built to give AI agents a permanent, searchable memory through the Model Context Protocol โ€” so knowledge is captured once and reused forever, across sessions and projects. It even dogfoods its own memory to help build itself.

Which are the primary technologies used for building your product?

ContextForge.dev's answer:

Next.js 16 (App Router), React and Tailwind CSS for the dashboard, hosted on Vercel. Supabase (PostgreSQL) with pgvector powers the semantic vector search, and Deno edge functions serve the API. Embeddings use OpenAI text-embedding-3-small. The MCP client is a Node.js package (contextforge-mcp) on npm, implementing the Model Context Protocol.

  • How do hackers hide their ip in reverse shells?
    I once used portmap.io for reverse shell in ethical hacking classes. Source: about 3 years ago
  • OpenVPNnot working and i dont know what to do
    So I use portmap.io for OpenVPN like I saw in tutorials but I found out it is not working because my ip didn't change when I looked up what my ip was. Source: about 3 years ago
  • SSH into a personal computer in Jio Network using public IP
    I have a personal computer in the Jio Network at my home and I want to access it using ssh from another network. But in order to port forward my router I am stuck since Jio uses CGNAT if I am not mistaken and there is no use if I portforward. What other solutions do I have? I tried using portmap.io but I couldnt configure ssh in it (I dont want to use openVPN) so what other options do I have? Source: over 3 years ago
  • port forwarding/tunneling
    I'm basically looking for a free version of https://portmap.io/ -- they will do this, but custom domains are $4/month. Source: almost 4 years ago
  • port triggering to replace port forwarding
    I would recommend trying again with port forwarding, or some other solution like this: https://portmap.io/ which is a kind of reverse tunnel made for situations like yours. That site has a free tier which allows a single forward. Source: almost 4 years ago
