In California (and Connecticut), you don’t have to pay to use the air pumps at gas stations. You can just go inside and ask them to turn on the air pump, and they legally have to.

Not free as in freedom, but gratis. Also only works for people who are on Discord - FreeStuff Bot will notify you every time a game on one of the popular PC platforms is available for free.
Your local city college may or may not offer free classes (in San Francisco, you just need to show proof that you live in the city with some legal status).
Some public transportation is free for certain groups (youth and folks experiencing homelessness can get free passes here).
"First X of the month" at the zoo/a museum/whatever --- lots of venues have free events.
A jog, bike ride, hike --- lots of great stuff outside!
In most eu countries the law requires businesses that give out food to also allow you to order free tap water. If youre in a city and dont want to spend money on a bottle of water, walk into mcdonalds and ask for free tap water. A lot of european countries also have strict laws about tap water so for example in france unless otherwise indicated with a warning, tap water is always potable.
In terms of fully free, obligatory mention:
Your library may offer more than books alone, depending on how well supported they are. Borrow music, movies, sometimes even video games. For music and movies they may also offer these to borrow digitally as well via online services they coordinate with.
A little late but OpenTaxSolver - free desktop tax software that gives you a printout of tax forms that you can mail in. And it includes a few states too. Way easier than the annoying corporate sites that constantly log you out and charge a fee for every little thing.
Edit: To my non-American friends, you don't need to worry about this
Let's stick with Project Gutenberg - Public domain ebooks and other media, spanning centuries. They're incredibly important for keeping our literary past alive.
Closing your eyes, slowly taking a deep breath, and calmly, breathing in, and breathing out, while focusing on the sensations in your body, and how much more relaxed you're feeling right now
Basically the earth has been segragated into 10 foot x 10 foot squares that are easily identified by 3 words, super accurate, easy to tell emergency services. No more need to know lat/long to tell someone where you're at.
lichess.org is a fantastic online chess platform for players of all skill levels. it's free and---what's more--it's ad-free (unlike the parasitic organisation that's squatting on the chess.com domain).
it has one-on-one on-demand match-ups, tournaments, puzzles, user-published training courses, multiple chess variants, and so much more.
it's one of only two online resources to which i deem donating regularly worthwhile (the other being wikipedia).
do check it out. chess is one really healthy mental habit to inculcate.
I know lemmy is social media for people with a favorite Linux distro so I’m preaching to the choir here, but so much software is free as in speech it is truly wonderful. It’s like the only thing I love about being a millennial
VLC: the only media player you’ll ever need. Peak FLOSS.
Audacity: free, robust audio editing/effects tool. Not a proper DAW but so feature rich some people treat it like one. Another peak FLOSS.
Freesound.org: huge library of free audio, all Creative Commons/non royalty shit. Effects, music, you name it. Been around for literally 2 decades, is run by a non-profit. Definitely a relic of a bygone era
Maybe this is sorta dumb, but meditation is a free way to feel good and spend time, and also a free method of stress relief and to reduce suffering.
It's not free in terms of your time & energy, and it might cost some money to learn, but the best meditation manual I know of is free online, or at least it used to be - it looks like it was locked down on archive.org (where it used to be freely available), but you can still find it on Anna's Archive, and you can probably find it at your local library. Either way, you can learn to meditate for free, that's how I did it.
Running is likewise relatively free (you do generally have to pay for running shoes, and athletic clothing can be expensive, but it's relatively cheap over the lifetime of those items, and it's cheaper than most other activities). A great and accessible way to feel good and stay healthy.
