Local macOS scanner that blocks secrets and PII from leaking into AI coding-tool prompts, for engineers who don't want to rely on cloud DLP.

Domain registered 4 months ago

FreeWorks offline
What to know
How it works
A macOS app that scans prompts in real time before they reach AI coding tools like Cursor, Claude Code, and Copilot, flagging leaked API keys, credentials, and PII using 47 local detection rules in under 50ms.
What's different
Detection happens on-device before data leaves the machine, and uses soft notifications instead of hard blocks so it doesn't interrupt the coding flow.
Pricing
Free 15MB macOS application for engineers; an early-access dashboard is offered separately for organizations.
Best for
Engineers using AI coding assistants who want to avoid pasting live secrets into prompts.

A low-memory graph database for serving large local replica graphs over the standard Bolt protocol.

What to know
How it works
Serves graphs that don't fit in memory — hundreds of millions of nodes and billions of edges — in low hundreds of MB of RAM, over the standard Bolt protocol so existing Neo4j drivers work, with disk-native vector search alongside the graph.
What's different
Resident memory is set by a chosen cache budget rather than by graph size, and it takes live durable writes without giving that up.
Best for
GraphRAG and LLM memory use cases needing local replica graphs.

Tools for developers — the short answers

Every number here comes from our own daily check — not from a vendor list.

Tools for developers — how many are there?
Tablif is tracking 1024 of them. 980 answered our check today, and 32 we couldn't reach — we don't claim those are dead.
Which ones are still maintained?
Tablif knocks on every door once a day and records the answer. 980 of these 1024 responded on the latest run, so that number is what "still here" means on this page — not a review score.
Are any of them free?
246 of the live ones say so in their own words, and 113 let you start without making an account. Tablif records the claim the product makes; we don't verify pricing.
Any open-source options?
93 of the live ones on Tablif mention being open source.
What's the newest one?
Skripr — Tablif first saw it today.
Did a person actually look at these?
1024 of them Tablif opened and read, then wrote a one-line summary in our own words instead of reusing the founder's tagline. The rest carry keyword labels we haven't confirmed by reading yet — and we say so rather than hiding it.
