Emisar.dev
Emisar is the last MCP server youโll need to install: a Zero-Trust gateway connecting Claude, Cursor, ChatGPT, and any AI agent to your infrastructure. One server handles production access, debugging, alerts, and internal operations, with new capabilities added as packs. Agents can inspect real production state, debug what they shipped, and help resolve incidents. Safe reads run automatically; policy allows, blocks, or routes risky actions for approval. No SSH keys, VPNs, remote shells, or standing shell access โ and every call is recorded.

AFFiNE's answer
AFFiNE is unique because it combines flexibility with strong privacy protections, making it ideal for users who value both control over their workspace and data security. The platformโs canvas feature allows for a highly customizable layout, enabling users to visually organize information in a free-form, drag-and-drop manner. This flexibility supports diverse workflows, from brainstorming and project planning to note-taking and task management, making AFFiNE a versatile tool adaptable to personal and professional needs.
What sets AFFiNE apart even further is its commitment to privacy with a local-first approach. This means data is stored locally on usersโ devices, safeguarding sensitive information and ensuring full offline access. As an open-source platform, AFFiNE also invites community contributions and customization, allowing users to shape the tool to fit their specific requirements. This blend of privacy, flexibility, and user-driven development creates a truly unique productivity solution.
Emisar.dev's answer:
emisar lets AI agents work on real infrastructure without giving them a shell. Agents choose from a finite catalog of typed, versioned actions. Policy decides what runs, what requires approval, and what is denied, while an outbound-only runner verifies the action again on the host. New capabilities arrive as packs behind the same MCP integration, and every request is recorded in both a searchable audit trail and a tamper-evident host journal. [
Emisar.dev's answer:
emisar is for SRE, DevOps, platform engineering, infrastructure, and security teams that want AI agents to inspect and operate production systems. It is especially relevant to teams managing multiple Linux hosts, clusters, databases, cloud services, or regulated environments where unrestricted shell access and incomplete audit records are unacceptable.
Emisar.dev's answer:
The hosted control plane and operator interface use Elixir, Phoenix, LiveView, PostgreSQL, and Tailwind CSS. The host runner and MCP bridge are written in Go. Action packs use YAML and JSON Schema, while production infrastructure is managed with Terraform on Google Cloud. The system communicates through MCP, OAuth 2.1, TLS, and WebSockets.

Emisar.dev's answer:
Founder Andrii Dryga spent a decade working as a CTO, full-stack engineer, SRE, and DevOps engineer. He experienced the cost of running the wrong command on the wrong cluster, while also seeing AI solve operational problems in seconds. emisar grew from the need to preserve both truths: AI agents are useful, and production access must remain bounded. Its answer is to give agents a reviewed catalog of operations instead of a blank terminal.
Emisar.dev's answer:
Choose emisar when you want an agent to keep investigating and handling routine operations without handing it SSH credentials or supervising every call. Compared with raw shell access, copy-paste workflows, or one-off MCP servers, emisar provides reviewed action contracts, host-level enforcement, risk-based policy, scoped access, approvals, pack integrity checks, and a durable audit trail. It is built specifically for governed infrastructure access rather than generic automation.

I'd say Affine or Obsidian. Obsidian is built on-top of just markdown files, so you can do whatever you want with them. E.g. If you need multiplayer editing you could use 3rd party solutions or even something like HedgeDoc. Affine is more closer to Notion and self-hostable.

I wrote a more detailed comparison of Notion vs Obsidian here: https://bryanhogan.com/blog/notion-obsidian-comparison I kinda dislike where Notion is heading though, forcing more and more things on their users without any ways to disable them. But yes, it's capable to do what you are looking for. Maybe Affine could also work though, you can self-host it and it's more customizable: https://affine.pro/. - Source: Hacker News / 3 months ago
AFFiNE is a workspace that merges docs, whiteboards, and databases into one tool. The editor supports block-based writing similar to Notion, but adds an infinite canvas (whiteboard) mode where blocks can be freely positioned. It's built with TypeScript/React and uses PostgreSQL and Redis for the self-hosted backend. - Source: dev.to / 5 months ago
I made the jump to AFFiNe (https://affine.pro/) a few months ago and have really liked using it. I am able to self host and have found it to be a _nearly_ 1:1 replacement for Notion. Affine's database implementation isn't nearly as nice though - but they are workable and they are improving. My biggest gripe is that the OSS project is very oriented around a hosted product rather than the self hosted - so things... - Source: Hacker News / 11 months ago
Affine : https://affine.pro/ You can self host too if you like. Not all features as Notion but comes very close. Seems more private too compared to Notion. I am also looking for more private and secure Notion alternatives. My company doesnโt allow using Notion. I like templates, tasks, scrum etc. Which I use for personal use. But I am reluctant on saving any personal information in it. - Source: Hacker News / about 1 year ago
