Open Source Ad Server vs. Hosted Ad Server — Which is Better?
If you’re a marketer looking for the best ad server to run your ads, you might have wondered if you should choose an open source or hosted ad server.
But before that, what are ad servers really?
You may have wondered how ads appear across the websites, apps & platforms you visit. These are usually publishers, who provide ad space for advertisers to show ads and target their audience. Behind this is the ad placement server, which serves the ads to a target audience.
Ad servers play a crucial part in digital advertising. It allows advertisers to manage, test, optimize, and replace ads that they serve.
Let’s go through what an ad server does.
What Is An Ad Server?
An ad server is a technology platform used to manage, serve, and track ads.
Used typically by advertisers (although there are ad servers for publishers too), it helps them target and serve ads to multiple platforms, including ad networks and DSPs – all while tracking & optimizing under a single advertising platform.
Imagine the world of digital media buying without ad servers.
For an ad campaign, a media buyer would have to manually contact a publisher to negotiate, create compatible ad formats and sizes, insert ads, and track and optimize. While this approach might work if the ad request requirement was to serve ads on one or two sites, imagine the workload if the need was to serve ads on hundreds of sites at once – each publisher with their creative ad requirements and measuring capability.
Enter the ad server to solve this problem.
With an ad server, the advertiser simply uploads his or her ad, social media, Facebook, or video ad, sets targeting rules into the ad network, and serves on multiple websites and apps using a single “ad tag.” Then, as the campaign runs, they measure and optimize the performance of their ads right in the ad server dashboard in real-time without having to contact every publisher for changes.
What Is An Open Source Ad Server?
There are two types of ad servers available, each with their strengths and weaknesses. Let’s go over what an open source ad server is first, so we can make a self-hosted vs. open source ad server comparison.
An open source or self-hosted ad server is ad server solutions that you host on your own server. While the server script or system is usually free these days, you have minimal options when it comes to open source ad servers.
- Free or cheap to use. Most open source ad serving systems are free.
- You have full customization flexibility over them.
- You own 100% of the data collected and can do anything you want with it.
- While the ad serving software usually has a free version, you still need a server to run the ad software, which could get expensive.
- You’ll need a dedicated technical team to work on updates and fix technical issues regularly.
- Ad serving & tracking reliability may be an issue with some open source ads or open source ad servers.
- An open source software may lack features that you need. You would have to build the features yourself or buy expensive plugin scripts as add-ons for your ad server open source.
What Is A Hosted Ad Server?
A hosted ad server essentially means an ad server software that is maintained or sold as a platform by an advertising network company. You simply subscribe and start using it without having to do much technical setup.
Hosted ad server companies usually have a dedicated support team that you can depend on for help, customization, and updates.
- There is no need for any technical setup. Just sign up and start using it.
- Support: Most ad server companies have 24/7 support and will be quick to help if any technical issue arises.
- Updates and bugs are taken care of for you. Most of the time, you won’t even notice the updates made by ad serving companies to cater for the changes in the AdTech landscape.
- Pricing wise, hosted ad servers usually cost more. Typical billing structures for hosted ad servers are pay-per-use and subscriptions.
- Customizations could be limited with some hosted ad servers, depending on the vendor you choose.
- The data you gather from ad campaigns are stored within the hosted ad server. Some advertisers are sensitive to allowing 3rd party ad servers to store their data.
Which Option Is Better And Why?
The problem with open source ad servers is that they barely get updates and are often buggy – something you want to avoid when running a critical advertising campaign.
You may perceive that choosing an open source ad server means extra savings, but don’t forget the other costs involved. For instance, to set up and maintain an ad server, you would need to hire a team of engineers. And while mobile ad server scripts or systems may be free, you still need to invest in a capable server to host the ad server, which isn’t exactly cheap, either.
This is why most advertisers, marketers, and media buyers turn to hosted ad servers. Besides its reliability and guaranteed uptime, advertisers see choosing hosted ad servers as a smart decision as they can entirely leave the technical work to the ad serving company and put more focus on the actual media buy and campaign strategy.

4 – Google Ad Manager (Formerly DFP & AdX)
Google Ad Manager is a unified ad platform of what used to be DoubleClick for Publishers (DFP) and the DoubleClick Ad Exchange. This unification (June 2018) was made along with the rebranding of Google Adwords to Google Ads – an attempt to simplify their solutions for advertisers & publishers.
Back then, DoubleClick used to be an ad serving platform for publishers to sell ad inventories. Moving into an ad landscape where Google believes all media buying should be programmatic, they introduced Ad Manager. They integrated everything under a platform, thus breaking away from standalone ad servers and supply-side platforms (SSPs).
Google Ad Manager is made for publishers who want to monetize through Google ad exchanges on placements where users are engaging, such as AMP pages, mobile games, live streams, connected TV and YouTube, and Apple News.
- Free to use: Google Ad Manager is a free ad server solution for publishers.
- Integrated solution: It’s an ad server and SSP (supply-side platform) combined.
- Revenue Optimization: Provides great control for publishers to choose who has access to their inventories.
- Multiple Platforms: Google ad manager is a single platform to serve, measure, and optimize ads wherever potential audiences are, including connected TVs, Accelerated Mobile Pages (AMP), mobile games and other apps, and platforms like YouTube and Apple News.
- Brand Safe: The platform protects publishers from ad fraud, inappropriate ads, and annoying ads that might hurt user engagement.
- Made for publishers only: It is not exactly a con, but note that Google Ad Manager is not an online advertising ad server. It is a publisher ad server.
- Google Networks only: When you use Google platform, you limit your inventories to the networks under Google only. Understand that one of the reasons marketers use ad servers is so they can run ads on multiple ad exchanges and DSPs at a single time.
Open Source Ad Servers
As mentioned earlier, you don’t have as many options for open source ad servers these days, probably due to fewer marketers using them. Here’s a popular one that has been around for some time:
Revive Ad Server
Revive Ad Server is made for advertisers, publishers, and ad networks. It’s, in fact, an ad server script that allows you to manage multiple ad campaigns at once, featuring basic targeting options such as frequency capping, geo-targeting, and URL targeting.
A reporting dashboard is included within the ad serving script. You still have to purchase plugins to add sophisticated reporting, such as reporting on country statistics, map statistics, or frequently viewed banner lists, to name a few.
While the Revive ad unit is free to use, its ad serving options utilize vast server resources, so you will need to get a server with enough space and bandwidth limit, and ensure all technical requirements are met to ensure smooth ad serving.
On another note, Revive has announced that they will be rolling out their own hosted ad server version which, was due to launch in Q4 of 2018. However, as of the date of writing, we’ve not seen it launched yet, except for a Revive ad server demo.
- Free: Revive ad serving system is free to use, and there are no ad serving fees.
- Data: Data collected from your ad campaigns will be stored on your own server, so all data is entirely yours to control.
- Standard reporting: From impressions, clicks, click-through rates, conversion rates, revenue, eCPM, and conversion details, like basket value and number of items purchased.
- Technical setup: Will require lots of technical setups and is best for more prominent companies that have a dedicated professional technical team and resources to host the ad server system.
- Filled with bugs: Not only is the system resource hungry, but it can be buggy as well. Prepare to work on daily troubleshooting and updating.
- Plugins: Need extra ad serving features like VAST or VPAID? Unless you can build them yourself, you’ll need to purchase script add-ons.
You should have a good idea when choosing between an open source ad server or a hosted ad server. Given the flexibility, affordability, and peace of mind you get, we would advise you to go for a hosted ad server.
That being said, there are still some merits in choosing to set your own ad server up with an open source ad system.
