Immunefi is now indexed. They're not in arkadiyt/bounty-targets-data, so I wrote a scraper for their site directly. 181 programs, ~2,900 in-scope assets, top payout is LayerZero at $15M. If you don't touch web3, ignore. If you do it's the same filter/search UI as the rest.
Per-program RSS feeds. Every program page now has an RSS feed of its scope changes at /rss/programs/{platform}/{slug}. Each entry is a diff: what was added, removed, or if the reward/safe-harbor changed. This is the free version of what bbradar.io gates behind their 89/yr Pro tier. Point your feed reader (Feedly, NetNewsWire, whatever) at any program you actually care about.
7-day activity chip on program pages. A small +N M 7d indicator when scope has actually changed recently. Answers "is this worth looking at today or is it dormant" without clicking in.
Company logos on program hero. Small polish, but the platform-only dot was ugly and hard to scan when you had a bunch of tabs open.
