CommaFeed vs Memos: at a glance
What is CommaFeed?
CommaFeed is patching its way through the attack surface a self-hosted reader inherits
CommaFeed's 7.x line has become a sustained security pass. The newest patch closes Host header injection on the password recovery endpoint and adds a commafeed.password-recovery-public-base-url setting so the email base URL is configured rather than taken from the request. Behind it: local address blocking made secure by default alongside Google Reader API support in 7.3.0, javascript: URLs filtered at parse time in 7.2.1, and SSRF limits on the image proxy in 7.2.0.
What is Memos?
Memos is turning a personal note store into an agent-addressable, private-by-default service
The release candidates in this window carry unusually heavy changes for a self-hosted note app: an embedded MCP endpoint exposing memo CRUD, comments, attachments and tags to AI clients; live updates over server-sent events; revocable share links; and a browser Web Clipper for saving pages and selections as Markdown. A parallel candidate makes instances without an explicit instance URL run in private mode and rewrites filters onto CEL timestamps.

◆ Current state
CommaFeed's 7.x line has become a sustained security pass. The newest patch closes Host header injection on the password recovery endpoint and adds a commafeed.password-recovery-public-base-url setting so the email base URL is configured rather than taken from the request. Behind it: local address blocking made secure by default alongside Google Reader API support in 7.3.0, javascript: URLs filtered at parse time in 7.2.1, and SSRF limits on the image proxy in 7.2.0.
◆ Where it's heading
Every release in this stretch closes a path where content or a request from outside the instance was trusted too far - feed URLs reaching internal addresses, proxied images, javascript: links, and now a header shaping an outbound email. That is the checklist of a project being run as a multi-user hosted service rather than a single-user tool, and it follows directly from the 7.0.0 decision to sandbox filter expressions. Feature work continues in parallel but is clearly the smaller half.
◆ Prediction
The remaining untrusted-input surfaces - OPML import and the feed fetcher's redirect handling - are the likely next targets. The pattern of shipping each fix as its own patch release should continue rather than batching them.

Memos is turning a personal note store into an agent-addressable, private-by-default service
◆ Current state
The release candidates in this window carry unusually heavy changes for a self-hosted note app: an embedded MCP endpoint exposing memo CRUD, comments, attachments and tags to AI clients; live updates over server-sent events; revocable share links; and a browser Web Clipper for saving pages and selections as Markdown. A parallel candidate makes instances without an explicit instance URL run in private mode and rewrites filters onto CEL timestamps.
◆ Where it's heading
Two directions are converging. One is machine access — MCP moved from a stateful server with prompts and resources to a stateless, tools-only endpoint generated from the OpenAPI schema, which is a deliberate narrowing toward something agents can call reliably. The other is defaults that assume the instance is private until an admin says otherwise. Together they reposition Memos from a personal web app to a small API-shaped service with a human UI on top.
◆ Prediction
Expect the MCP surface to stabilise against the OpenAPI schema as the source of truth and the private-by-default posture to carry into a general release, with clients that relied on prompts, resources or unprefixed tool names needing to migrate.
