built an open source local version - goldfish - for my particular use case, seeing if I can elegantly tie in session history knowledge for agents to lean into when needed, without leaking personal stuff.
give new sessions our thinking context.
one sqlite file on my machine, served over MCP. you choose what it remembers, scope what each agent sees, audit what they read.
my use is claude code in terminal as daily driver, but also running sessions in hermes on a mac mini, cursor, the claude app itself and gpt codex... all don't talk to each other well other atm than in handover.md
running it on myself for a week as an open experiment, contributors welcome
