MoonMark · Markdown reader for Mac, made for AI agent docs

Claude Code, Codex, and other agents write their plans, designs, and analyses to .md files. MoonMark shows them with an outline on the left, a readable text column, and formatted tables, code, and diagrams. When an agent rewrites the file, MoonMark reloads it and keeps your reading position.

Session store migration: Redis → Postgres
Generated by Claude Code · 2026-09-28 · Awaiting review
Session data lives in a single Redis instance with persistence turned off. Two restarts last week each dropped about 40,000 logins. This plan moves sessions to the existing Postgres cluster and keeps Redis as a read cache.
Recommendation: C — the same durability as B, with read latency close to current levels.
If dual writes conflict during the backfill, Postgres wins. Freeze changes to the session schema before the backfill starts.
Reads are controlled by the SESSION_READ_FROM_PG flag. Turn it off to fall back to Redis. No redeploy needed.
Pick a theme. Click a heading in the outline to jump to it. Click </> to see the Markdown source of this sample.
In raw Markdown, a table is rows of pipe characters and a diagram is a block of code. MoonMark shows them formatted.
Agents often rewrite a file while you are reading it.
By default, when the file changes on disk, MoonMark reloads it. You stay at the paragraph you were reading.
Other tools do these well.
MoonMark is for reading Markdown.
Each of these is good at its own job. Choose based on what you do with the file.
