Keelson

Keelson turns an app you built with an AI coding tool into something your team can actually use. Deploy the app and it gets a URL protected by company sign-in: only the members you choose can open it, and you never write authentication code yourself. Each app runs as its own isolated service with its own managed SQLite database, separated from other apps and other customers. Databases are backed up daily, and you can restore to a point in time. Scheduled jobs, access logs, app logs, secrets, and IP allowlisting are built in. Keelson works with Claude Code, Codex, and Cursor through an agent skill, so the AI tool that built the app can also deploy it. A CLI is available for macOS, Linux, and Windows. Apps are hosted in Tokyo. Plans start at $29 per month, with a 14-day free trial. The Starter and Plus plans do not require a credit card to start.

Nexly

Nexly is a privacy-first product analytics platform for web, mobile, and backend applications. It combines traffic analytics, custom events, funnels, reports, and AI Insights in one dashboard so product and engineering teams can understand usage without invasive tracking. Teams use Nexly to measure pageviews, engagement, acquisition, and product events in a single workspace. Custom events and funnels help you see how users move through key flows, while reports and trends make it easier to spot what changed and why. AI Insights turn raw metrics into plain-language summaries that are easier to act on in day-to-day product work. Nexly also includes a hosted, read-only MCP server secured with OAuth 2.1, so teams can analyze their analytics data from Claude, Cursor, Codex, and other OAuth-capable AI tools without giving those tools write access to the product. The Streamable HTTP endpoint is available at https://api.nexly.to/mcp, and Nexly Analytics is listed in the official MCP Registry as to.nexly/analytics. Documentation for the MCP integration is available at https://www.nexly.to/help/api/mcp. Pricing is freemium and based on event volume. Every plan includes the complete feature set rather than locking core analytics behind higher tiers. That means traffic analytics, events, funnels, reports, and AI Insights stay available as usage grows, while cost scales with the volume of events you collect. Nexly is currently in beta and is built for SaaS companies, startups, and product teams that want actionable product and web analytics with a privacy-first approach. Typical buyers include product managers, growth teams, and engineering leads who need reliable product analytics without turning their site or app into a surveillance stack.

Nexsus

Nexsus — The substrate is a private workspace your AI assistant connects to over the open Model Context Protocol (MCP). Once connected, your assistant gains a persistent, structured memory: it reads, stores and reasons over your data across every session, instead of starting from scratch each conversation. Every customer gets a separate, walled-off workspace, isolated at the database level — your data is never mixed with anyone else's. Nexsus understands meaning, not just values: records carry structure and are searchable semantically, and the platform keeps a complete history of every change so nothing silently drifts or breaks. Every write is checked against the workspace's own correctness rules before it's accepted, and if a write would break structure, you get back the specific reason, not a generic error. Nexsus works with Claude, ChatGPT, Gemini, Claude Desktop, and any other client that speaks the open MCP standard — one workspace, every assistant. There's nothing to host: sign up, add your Nexsus MCP server URL as a connector, authorise once with OAuth, and you're working. You own your data — export any time, and deleting your workspace deletes it for good.

In the listing view you can also switch between table view, kanban view and a timeline view, depending on what works best for your data. Import / export: move data in and out of pylo with our CSV and JSON importer / exporter. When you import data, define to which fields it should be mapped, define fields as search values to use them as keys and add replacement operations to sanitize your data.
