The best free event planning tools aren't a single app that does everything. They're a handful of focused tools, one per job: something to track RSVPs, something to message guests, a place to keep the budget, and a timeline for the day itself. Most of them you already have on your phone. Below I'll go category by category and tell you what to reach for, and when a free option is genuinely enough.
I've planned enough gatherings to know the trap: you sign up for some slick all-in-one platform, hit a paywall two weeks before the event, and end up back in a spreadsheet anyway. So this is the honest version. Pick what fits the size of your event and skip the rest.
RSVP tracking
This is the one job I'd never leave to a group text. Counting replies by hand across messages, DMs, and "I told you in person" is how you end up ordering food for 40 when 55 show up.
A dedicated RSVP tool gives you a link to share and a running headcount you can trust. RSVPlist is the free one I build and use: no signup, no account, no guest limit. You send a link, guests reply in a few taps on their phone, and a private dashboard (locked behind a password you set) updates in real time with who's coming and the total headcount, plus-ones included.
A couple of things that save real headaches. It checks names as people type, so you don't get "Sarah M" and "sarah m." as two guests, and if someone replies twice their answer quietly updates instead of piling up. You can add up to five custom questions for dietary needs or a song request, and when you're done you export the whole list as a CSV. For a door, there's a check-in mode with QR entry passes.
Match the link to the event
Guest messaging
Once people say yes, you'll need to reach them: parking notes, a dress code reminder, a weather change on the morning of. You don't need special software for this. A group chat in whatever app your guests already use does the job for free.
One caution. Group chats get noisy fast, and not everyone wants their number shared with strangers. For a big or formal event, keep the chat for close family and the wedding party, and send everyone else a single clear email instead. Your RSVP tool already has their contact info, so you're not building a list twice.
Budget tracking
A spreadsheet still beats every "event budget app" I've tried, and it's free. Make three columns: item, estimated cost, actual cost. Add a row for each thing you're paying for (venue, catering, cake, flowers, that inflatable you swore you wouldn't rent), and let the sheet total it up.
The magic isn't the formulas. It's that a shared cloud spreadsheet updates for everyone at once, so if you're splitting a party with a co-host, you both see the same numbers. Keep a "paid?" column too. Knowing what's still owed a week out is worth more than any fancy chart.
Timeline and schedule
Every event has a run of show, even a backyard birthday for 20: when the food comes out, when you do cake, when the music gets loud. Write it down. A shared calendar works well because you can drop in vendor arrival times and delivery windows, then share it with anyone helping.
For the day itself, I like a plain list with times down the left: "3:00 guests arrive, 3:30 food, 4:15 speeches." Print it or pin it in the group chat. When someone asks "what's next?" you point at the list instead of thinking on the spot.
One heads-up on reminders
Design and invitations
You can make a genuinely nice invite for free. Plenty of design tools have free tiers with event templates you drag your details into, and free stock photo sites cover the imagery if you want a background that isn't a phone snap.
Keep the design and the reply separate, though. A pretty image is for setting the mood; the actual RSVP should be a link people can tap, not a request to text you back. If you're fuzzy on where one ends and the other begins, this is worth a read: RSVP vs invitation, what's the difference.
Checklists
The cheapest planning tool is a checklist, and it's the one that keeps you sane. Any notes app or shared to-do list works. Break it into buckets by timing: one month out, one week out, day before, day of.
The trick is a "day of" list you can hand off. Write down the small stuff you'll forget in the chaos: bring the speaker cable, pick up the ice, tape the sign to the door. Then someone else can knock it out while you handle the rest.
File and photo sharing
You'll accumulate files: a venue contract, a seating sketch, the playlist, and a mountain of photos afterward. A free cloud drive folder holds all of it in one link you can share with co-hosts. For the photos, a shared album that guests can add to means you get everyone's shots without begging for them one by one.
How to put it together
Don't adopt all seven at once. For most events you need three: an RSVP link so you know who's coming, a budget sheet so you know what you're spending, and a checklist so nothing slips. Add a group chat and a shared photo album if the event is big enough to warrant them. That's a full free stack, and none of it expires on you.

Common questions
Are free event planning tools good enough for a wedding?
For most weddings, yes. The parts that actually need to be reliable are the guest count and the timeline, and both have solid free options. Paid all-in-one wedding platforms bundle extras like seating charts and registries, but you can cover those separately if you want them.
What's the one tool I shouldn't skip?
RSVP tracking. Everything downstream (how much food, how many chairs, how big a cake) depends on a headcount you can trust, and a proper form gives you that without the manual tally.
Do I need a paid tier to remove guest limits?
Not always. Some free tools cap how many guests or forms you get. RSVPlist has no guest limit and no paid tier, so a 200-person event costs the same as a dinner for eight.
How do I get more people to actually reply?
Make replying take seconds, set a clear deadline, and send one polite nudge to the stragglers. For party-specific tips, see the birthday party RSVP guide.
