Free Maps Without an API Key: What OpenFreeMap Means for Australian Businesses (and What to Check First)

OpenFreeMap puts OpenStreetMap maps on your website with no API key, no sign-up and no view limits, and you can self-host it. Here's what an Australian business should check first: attribution, no SLA, privacy and the gaps.

Free Maps Without an API Key: What OpenFreeMap Means for Australian Businesses (and What to Check First)

Free Maps Without an API Key: What OpenFreeMap Means for Australian Businesses (and What to Check First)

OpenFreeMap lets you put a proper, zoomable map on your website or app with no API key, no sign-up and no cap on map views, and you can self-host the whole thing. That's a genuinely useful option for an Australian business with a store locator or a service-area map. It also comes with no SLA, a licence obligation you can't skip, and a few gaps you'll need to fill yourself. Here's what we'd check before switching.

A map on a website looks like a small thing. Then someone asks where the key is stored, whose card it's billed to, and what happens if the site gets busy. For a lot of small businesses, the honest answer is "no idea".

OpenFreeMap came up in a Russian-language TikTok slideshow of eight open-source projects "quietly changing the internet". We checked every project on that list against its own site and code repository. All eight are real and actively maintained. None of them is an AI tool, by the way, even if a couple now pitch themselves to AI developers. OpenFreeMap is the one we think matters most to Australian businesses, so this post is mostly about it.

Figures below were checked on 2 November 2026 (AEDT). GitHub star counts are approximate and change daily. Stars measure popularity, not quality or safety.


What OpenFreeMap actually is

OpenFreeMap serves map tiles and map styles built from OpenStreetMap data. You point a mapping library at one of its style addresses and you get a working, styled map. Its website states the public instance has "no limits on the number of map views or requests" and "no registration, no user database, no API keys, and no cookies". Commercial use is allowed. The FAQ answer to that question is one word: "Yes."

A few more facts from the official site and repo:

  • Who's behind it. Zsolt Ero, who says he ran his own map tile infrastructure for MapHub for nine years before open-sourcing it as OpenFreeMap. The legal entity in the terms is Hyperknot Software Kft., based in Hungary.
  • How it's funded. Donations and GitHub Sponsors. The site says the aim is to cover the running costs of the public instance that way.
  • It's fully open source. The project is MIT licensed, including the full production setup. The site is explicit there's no "open-core" model, so you don't hit a paid tier for the good bits.
  • Weekly data. Full-planet downloads are published weekly, in Btrfs and MBTiles formats.
  • Approximately 6.3k GitHub stars as of 2 Nov 2026. github.com/hyperknot/openfreemap

It works with MapLibre, the open-source map library that grew out of the last open-source version of Mapbox GL JS. The quick start guide also covers Leaflet, OpenLayers and MapLibre Native for mobile apps.

Why does this exist? The site's own explanation is that commercial tile providers can bill you heavily if your map gets popular. It cites Hoodmaps getting a $10,000 bill in a single day. That's OpenFreeMap's anecdote, not something we've verified, and we're not going to quote you anyone's current map pricing here. If cost is your reason for looking, open your current provider's pricing page and your last few invoices. That's your real number.


Where it fits for an Australian business

OpenFreeMap is a good match for maps that show things: where you are, where you service, where your sites are.

Hypothetical example: a plumbing business in Sydney's Inner West wants a map on its website shading the suburbs it covers, with a pin for its depot. Today it uses a commercial maps API with a key someone set up years ago. With OpenFreeMap, the map is a style URL in MapLibre, there's no key to leak or rotate, and no usage bill if a post about them does the rounds on a local Facebook group. The suburb outlines are their own data, drawn on top.

Other fits:

  • Store and clinic locators for a chain with a handful of locations around NSW.
  • Property and project maps for real estate agents, builders and developers.
  • Event and venue maps for councils, festivals and community groups.
  • Internal dashboards showing jobs, deliveries or assets on a map.

And some places where it doesn't fit on its own. The project README lists what OpenFreeMap does not provide, by design: search or geocoding, route calculation and directions, static image generation, raster tiles, satellite imagery, elevation lookup, and hosting your own custom tile datasets. So "type your postcode to find your nearest store" needs a separate geocoding service. "Get directions" needs a routing service. Satellite views need another provider. That's not a flaw. It's a tightly scoped project. But it means "swap the map" is rarely the whole job.


What to check first

This is the bit worth reading twice. Free isn't the same as risk-free, and none of the points below is a reason to avoid OpenFreeMap. They're the things to decide before a customer-facing page depends on it.

1. There's no SLA, and the terms say so

The FAQ is direct: "At the moment, I don't offer SLA guarantees or personalized support." The Terms of Service say the service is provided "as-is" with no warranties regarding availability, and that it "may discontinue it at any time without notice", with changes announced on X and Bluesky where possible. The terms are governed by Hungarian law.

None of that is unusual for a free, donation-funded service. It's just the deal. Our view: for a contact page or a "where we work" map, that's an acceptable risk for most small businesses. For anything where a broken map stops revenue (a booking flow, a delivery app, a dispatch screen) you want either self-hosting or a paid provider with a contract. The site mentions a possible future Pro plan if there's interest, but that doesn't exist today.

2. Attribution isn't optional

OpenStreetMap data is licensed under the Open Database License (ODbL). The OpenStreetMap copyright page says that wherever you use the data, you must credit OpenStreetMap and make clear the data is available under the ODbL. Linking the credit to openstreetmap.org/copyright covers the second part.

OpenFreeMap adds its own requirement: "Attribution is required." If you use MapLibre, the attribution is added automatically. If you use another client, or put the map in print or video, you must add "OpenFreeMap © OpenMapTiles Data from OpenStreetMap". The OpenFreeMap part is optional, but the site says it's nice if you include it.

The OpenStreetMap Foundation's attribution guidelines go further on placement. For an interactive map, the credit should typically sit in a corner of the map. It can collapse after interaction or five seconds, as long as people can still find the licence information. Designers sometimes hide map credits because they look messy. Don't. That's a licence obligation, not a style choice.

A small local detail we liked: the OpenStreetMap copyright page credits Geoscape Australia's administrative boundaries, licensed by the Commonwealth under CC BY 4.0. Australian government open data is part of what you're displaying.

3. Offline downloads have limits

If your app lets users save map areas for offline use (handy for field staff in regional areas with patchy coverage), each download must be at most 3,000 tiles or 50 MB, use at most four parallel requests, and send a unique User-Agent identifying your app. Anything bigger, you contact them first. These limits are in the Terms of Service as well as the FAQ. The terms also rule out collecting data from the service in automated ways outside those offline downloads, so bulk-scraping tiles is out.

4. Know where your visitors' requests go

When someone opens a page with an OpenFreeMap map, their browser fetches tiles from OpenFreeMap's servers. Like any web request, that reveals their IP address to the server answering it.

OpenFreeMap's privacy policy is better than most here. It says access logs don't contain IP addresses by default, error logs may include IP addresses and are deleted after seven days, and IP logging may be switched on for up to 30 days during a security incident. It also says the service may use Cloudflare as a CDN, and Cloudflare may collect information under its own privacy policy.

What we'd do: list OpenFreeMap (and Cloudflare) wherever your privacy policy names third-party services your site uses, and if you handle sensitive customers, ask your privacy adviser whether anything more is needed. We're not going to offer a legal conclusion on the Privacy Act here. Our Privacy Act and AI guide covers how we think about third-party data flows more generally.

5. Self-hosting is real, and it's real work

Self-hosting removes the dependency on someone else's donation-funded servers and keeps tile requests on infrastructure you control. You can put it on an Australian server if that matters to you. OpenFreeMap publishes the processed full-planet images, and the repo includes deploy scripts.

But read the README before you promise anyone a quick win. The scripts are built to set up clean Ubuntu 24.04 servers over SSH. The project is Docker-free on purpose. It's not something you install on a laptop. And the README says it "does not promise worry-free automatic updates for self-hosters". Self-hosting moves the risk to you: servers, storage, bandwidth, certificates, updates and monitoring. For most small businesses, the public instance plus a fallback plan is the better trade. For a larger organisation with a platform team, self-hosting is worth costing properly.

6. Have a fallback

Whichever way you go, design the page so a failed map degrades politely: a static address, a list of suburbs, a link out. Because MapLibre takes a style URL, moving to a self-hosted instance or another vector-tile provider later is usually a configuration change plus testing, rather than a rebuild, assuming you haven't relied on features specific to one provider.


The other seven projects on the list, briefly

None of these is an AI tool, and none replaces a mainstream product for a typical small business today. They're infrastructure, mostly of interest to developers. Star counts are approximate, as of 2 Nov 2026.

  • Electric (about 10.4k stars, Apache-2.0). A read-path sync engine for Postgres: it syncs data out of Postgres into apps and browsers. Writes still go through your own backend.
  • iroh (about 12.9k stars, MIT/Apache-2.0). Encrypted peer-to-peer connections where you dial a public key instead of an IP address, with stateless relays as a fallback. Its free public relays are rate-limited with "No uptime guarantee". Managed relays start at US$19 a month, and the relay software can be self-hosted. Same SLA lesson as OpenFreeMap.
  • AT Protocol (about 9.7k stars, MIT/Apache-2.0). The open protocol Bluesky runs on. User numbers on atproto.com are Bluesky's own figures, not an independent audit.
  • Ladybird (about 66.8k stars, BSD-2-Clause). A new browser engine built from scratch, not a fork of Chromium, Gecko or WebKit, backed by a non-profit. As of 2 November 2026, its site says the first alpha for macOS and Linux "is coming later this year", aimed at developers and early adopters. So: not released, not something to roll out to staff.
  • Automerge (about 6.7k stars, MIT). A CRDT library for local-first apps, where people edit offline and changes merge automatically. Automatic merging is deterministic. That doesn't mean the merged result is always what each person intended, so apps still need sensible design.
  • Helia (about 1.3k stars, Apache-2.0). A TypeScript implementation of IPFS for browsers and Node.js.
  • PeerTube (about 15.3k stars, AGPL-3.0). Federated video hosting developed by the French non-profit Framasoft. Its peer-to-peer playback helps lower server load, and its own privacy guide notes viewers' IP addresses are visible to the tracker and to other peers watching the same video. Admins and users can turn P2P off. If you'd host video for customers, look at that with your privacy obligations in mind.

One more on licences, because the slideshow ended by promoting GitButler as an open-source find. GitButler's licence is the Functional Source License (FSL-1.1-MIT): you can use it for anything except a competing commercial product, and each version becomes MIT two years after release. That's source-available, not open source in the OSI sense. Licences on this list range from permissive (MIT, Apache, BSD) to network copyleft (PeerTube's AGPL-3.0, which generally means if you modify it and run it as a service, you share your changes). Read the licence file, not the hashtag.


Our take

We like OpenFreeMap. It's well scoped, honest about its limits, and clear about its rules: no SLA, attribution required, offline download caps. That honesty is a good sign.

For an Australian small business, our default would be the public instance with MapLibre for a location or service-area map, attribution left visible, OpenFreeMap named in the privacy policy, and a plain-text fallback on the page. We'd move to self-hosting or a contracted provider once the map becomes part of how you make money, rather than decoration.

What we wouldn't do is rip out a working maps setup just because something free exists. Price up what you'd need for search, directions and support, then decide.

FAQ

1Is OpenFreeMap free for commercial use?

Yes. OpenFreeMap's FAQ says commercial use is allowed, and the public instance has no registration, no API keys and no limit on map views or requests. You still have to show the required attribution.

2Do I need an API key to put a map on my website?

Not with OpenFreeMap's public instance. You load one of its style URLs in a library such as MapLibre GL JS and the map works without a key. Many commercial map providers do use keys, so check your current setup.

3What are the OpenStreetMap attribution requirements?

You must credit OpenStreetMap and make clear the data is under the Open Database License, usually by linking the credit to openstreetmap.org/copyright. For interactive maps the credit typically sits in a corner of the map. MapLibre adds OpenFreeMap's attribution automatically.

4Is OpenFreeMap reliable enough for a business website?

For a contact page or service-area map, often yes. But there's no SLA or personalised support, and the terms say the service is provided as-is and may be discontinued without notice. For revenue-critical maps, self-host or use a provider with a contract.

5Can OpenFreeMap replace Google Maps for a store locator?

It can replace the map itself. It doesn't provide address search, geocoding, directions or satellite imagery, so a full store locator needs other services for those parts.

6Can I host OpenFreeMap on Australian servers?

Yes. The full production setup is open source and full-planet images are published weekly. The deploy scripts target clean Ubuntu 24.04 servers, and you take on updates, bandwidth and monitoring yourself.
