Tools for collectors and hobbyists — the short answers
Every number here comes from our own daily check — not from a vendor list.
Tools for collectors and hobbyists — how many are there?
Tablif is tracking 158 of them. 152 answered our check today, and 4 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. 152 of these 158 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?
43 of the live ones say so in their own words, and 20 let you start without making an account. Tablif records the claim the product makes; we don't verify pricing.
Any open-source options?
4 of the live ones on Tablif mention being open source.
What's the newest one?
Airspace Live — Tablif first saw it yesterday.
Did a person actually look at these?
158 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.
