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.

Analysis of eBay

Overall verdict

  • Overall, eBay is a reliable platform for many users seeking diverse product offerings and opportunities for good deals, particularly in second-hand and unique items. However, experiences can vary depending on individual transactions, as the platform hosts a vast number of independent sellers.

Why this product is good

  • eBay is a well-known e-commerce platform that offers a wide variety of products through both auction-style and fixed-price formats. It provides a marketplace for sellers to reach a global audience and for buyers to find items at competitive prices. eBay offers buyer protection programs and a feedback system that helps foster trust among users. Additionally, it supports various payment methods and has a mobile app for convenient shopping.

Recommended for

  • Bargain hunters looking for competitive prices on both new and used items.
  • Collectors seeking rare, unique, or vintage products that may not be available elsewhere.
  • Individuals interested in participating in auction-style buying for potentially lower prices.
  • Sellers who want to reach a global audience to sell products ranging from handmade items to high-demand consumer goods.

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 eBay 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.

Poor policy: One of the main reasons prompting sellers to switch from eBay to other selling platforms is its controversial policy.

Etsy is similar to eBay in the way they charge a listing fee. Nevertheless, eBay listings are up to 10 days, or even 30 days for a fixed price, while Etsy allows listings for up to four months. Besides, Etsy charges only a $0.20 listing fee per item, plus a fixed 3.5% commission, making it a much cheaper alternative to eBay (and of course Amazon!).

  • Dad passed away, here is his collection.
    Then, if you want to sell certain ones or all of them, you could list them on Reverb.com or ebay.com or some site(s). I wouldn't advise Craigslist because you either have to let people into your home, go to their home or meet somewhere neutral, which can be tricky. Source: over 2 years ago
  • Help needed.
    First thing is get off the app. It's terrible for anything but basic selling functions. Open a browser and go to to ebay there. Best if you can use a computer or tablet for that, but it's doable on a phone even. Source: over 2 years ago
  • New collector help
    Ebay is the biggest market, but note that ebay.co.uk doesn't show the exact same results as ebay.com. There are also german, italian, spanish, and other versions of ebay that can offer surprising deals if you're clever about it. Also note that you can search for SOLD items on ebay, which is a good way to see how much a certain card was selling for last month or last year or whatever. Check the advanced search...
