PageIndex is a reasoning-based, vectorless RAG system for analyzing long professional documents without vector databases or fixed chunking. It builds a hierarchical “table-of-contents” style tree index from a document and performs retrieval via reasoning-driven tree search, aiming for more relevant, traceable results with page/section references. PageIndex can be self-hosted using the open-source repository, or used via a hosted chat platform and integrations such as MCP and an API, with enterprise deployment options for private/on-prem use cases.

Tailscale is a secure connectivity platform that creates a private mesh network (“tailnet”) between devices and services using WireGuard as the data plane and a control plane for identity, key distribution, and policy. It’s commonly used by developers to give servers, containers, and services private, authenticated access without exposing ports publicly. For AI agent developers, it’s useful for securely connecting self-hosted agent runners, internal APIs, databases, vector stores, and automation tools across clouds and local machines. Tailscale includes features like ACL-based access policies, MagicDNS, device sharing, subnet routing, and exit nodes for routing traffic through a trusted device.

memU is an open-source memory infrastructure for LLM applications and AI agents, designed for long-running, always-on assistants that need persistent, evolving memory. It organizes memories like a file system (categories as folders, memory items as files, cross-links as symlinks) and supports proactive behavior such as capturing user intent, predicting next steps, and injecting relevant memory into the agent’s context. memU aims to reduce token spend for continuous agents by caching insights and avoiding redundant LLM calls, and it includes companion components like a backend service (memU-server) and a web UI (memU-ui). In addition to the open-source framework, memU offers hosted APIs (Memory API / Response API) with usage-based pricing and a “start free” path.

Amp is an agentic coding tool by Sourcegraph that runs in the terminal and editor extensions (including VS Code and compatible forks). It is designed for complex coding tasks such as multi-file edits, planning, and execution using multiple frontier model options. Amp includes a threads feature to save and share interactions, and offers “Amp Free” with a daily credit grant supported by sponsor ads, plus pay-as-you-go usage with no markup for individuals after the free allowance.

Agentic coding tool for terminal and editors that uses multiple frontier models, with a free $10/day grant and pay-as-you-go pricing.

Mocha (getmocha.com) is an AI-powered no-code app builder that lets users create and ship full-stack web apps by describing what they want in natural language. It generates the app UI and backend logic and supports core production pieces such as user authentication, a database, and payments, with one-click publishing and optional custom domains. Mocha uses a credit-based system for AI usage and offers a free starting tier with paid plans for larger and more complex builds.

Codiga (now part of Datadog) is a customizable static code analysis platform that runs in IDEs and CI/CD to detect code quality issues, security vulnerabilities, duplicated/complex code, and leaked secrets. It supports custom rules and rulesets created in a browser and can provide automated code reviews on platforms like GitHub/GitLab/Bitbucket, with fast feedback and automated fixes (“autofix”) directly in the developer workflow. Codiga also includes a separate “Coding Assistant” product focused on team code snippets and reusable patterns integrated into popular IDEs.

Bright Data Web MCP is an open-source Model Context Protocol (MCP) server that connects AI assistants to the live public web with built-in unblocking to avoid CAPTCHAs and rate limits. It provides tools for real-time web search, page fetching and scraping (including via Bright Data’s web unlocker), and optional browser automation for navigating and interacting with dynamic sites. It supports a free “Rapid” tier (limited toolset and monthly request allowance) and paid usage-based modes that unlock additional tool groups such as browser control and broader web data tooling. It can be used via Bright Data’s hosted MCP endpoint or run locally via an npm package.
