    Self-hosted Prebid Server: what you run, what drives the cost and when it beats a managed host

    Published · Last updated

    By Art Kukharenko, CEO

    Self-hosted Prebid Server means running Prebid.org's open-source auction server, in its Go or Java build, on machines you control instead of a vendor's. The code is free under the Apache 2.0 licence. The bills come from compute, caching, load balancing, data transfer and the engineers who keep it patched (Prebid.org, accessed 9 November 2026).

    What it does

    Self-hosting gives you the whole server and every duty that comes with it. Prebid's hosting page lists four duties. You run production-grade servers, networking and monitoring, and you fill the stored-request and account data. You also own the legal side of ad tech in your market, and you check for updates at least quarterly (Prebid.org, accessed 9 November 2026). Prebid's FAQ confirms that anyone may host Prebid Server for themselves or for others (Prebid Server FAQ).

    The reward is control. You pick the bidders, the timeout, the modules and the analytics adapters. Bid logs land in your own systems. The uids cookie that carries each bidder's user ID sits on the domain of whoever hosts the server, which on this path is you (Prebid.org, user ID sync).

    This page treats self-hosting as one option next to the managed hosts in this series. The build itself, with topology, configuration and a full cost worksheet, is in the Prebid Server self-hosting guide. If header bidding itself is new, start with header bidding explained.

    How it works

    A self-hosted cluster has the same parts in every region. Prebid's hosting page describes them (Prebid.org):

    1. A global load balancer, if you serve more than one region, so each user reaches the nearest cluster.
    2. A regional load balancer or proxy that ends TLS, because neither Prebid Server nor Prebid Cache accepts an SSL certificate. It sends /cache requests to Prebid Cache and everything else to Prebid Server.
    3. Prebid Server nodes, which do a mix of network and CPU work and need memory to cache stored requests and GDPR vendor lists.
    4. Prebid Cache nodes and a NoSQL store, for video and AMP creatives.
    5. A database for accounts and stored requests, replicated to each region.
    6. A metrics system: InfluxDB or Prometheus for the Go build, with Graphite and console output also available in Java.

    The database is the part teams underestimate. Prebid notes that there are no open-source tools to fill it, so each host builds its own feed from its ad ops systems (Prebid.org). What goes into it is explained in Prebid Server stored requests.

    Pick a build before you size anything. Prebid recommends Go for new bid adapters and for long-form video; otherwise, it says, choose the language your engineers are most comfortable reading and changing (Prebid.org versions overview).

    Pricing: cost drivers, not totals

    The software costs nothing. Everything else depends on your traffic, so this page gives drivers and unit prices, not a monthly total. Prebid's hosting page publishes no capacity or speed figures, which means requests per second per server must come from your own load test (Prebid.org).

    The prices below are AWS on-demand list prices for US East (N. Virginia), read from AWS's public Price List files in November 2026. Other clouds publish their own pages.

    One published anchor exists. AWS says its reference deployment costs about $241.50 a month in US East with no bidding traffic at all, a figure it dates "as of July 2023" (AWS estimate) (AWS guidance README). That covers an idle stack only. To turn the drivers into your own monthly figure, use the worksheet in the Prebid Server self-hosting guide.

    Strengths and limits

    Strengths

    • No host fee. The licence is free, and no revenue share goes to an intermediary for running the auction (GitHub).
    • Full control of the auction. Bidders, timeouts, modules and analytics are your settings, not a vendor's.
    • Your data stays with you. Bid logs and the uids cookie sit on infrastructure and domains you choose (Prebid.org).
    • A choice of build. You can pick Go or Java for features and for your team's skills (Prebid.org).

    Limits

    • Constant upkeep. Each build shipped 13 tagged releases in 2026 to early November, and both needed critical fixes in June (GitHub).
    • You build the data feed. No open-source tool fills the account and stored-request database (Prebid.org).
    • User matching starts from zero. A new server's uids cookie holds no bidder IDs until users pass through sync, whereas a large shared host may already hold them.
    • Legal set-up is yours. Prebid says the host must understand the legal side and configure privacy features with its lawyers (Prebid.org).

    Alternatives

    Managed hosts take the operations work in exchange for a fee and some control:

    Prebid.org lists 21 managed-service providers in all (Prebid.org, accessed 9 November 2026). How Prebid compares with Open Bidding and Amazon's marketplaces is set out in Prebid vs Open Bidding vs Amazon TAM. The case for owning more of the sell side is on the publisher independence hub.

    What we could not verify

    • Requests per second that one server handles at a given latency. Prebid publishes no figure, and we found no neutral benchmark.
    • Bytes sent per auction response, which drives the data-transfer line. It depends on bidders, formats and caching.
    • A current AWS re-pricing of the reference deployment; the README still dates its idle estimate to July 2023 (AWS guidance).
    • Prices outside US East and on Google Cloud or Azure; we link the official pages but did not read figures from them.
    • Who runs self-hosted Prebid Server in production, beyond the public examples above.

    FAQ

    Is Prebid Server free to self-host?
    The software is free under the Apache 2.0 licence (GitHub). Running it is not: you pay for servers, caching, load balancers, data transfer and engineering time.
    How much does it cost to self-host Prebid Server?
    There is no single figure, because cost follows your traffic. On AWS in US East, a c7g.xlarge server lists at $0.145 an hour and data out to the internet at $0.09 per GB after the free 100 GB, as of November 2026 (AWS Price List). The self-hosting guide shows how to combine the drivers.
    Should I self-host or use a managed Prebid Server?
    Self-host if you have engineers to patch a server that ships new releases every few weeks, and if owning the bid data matters to you. Choose a managed host if you lack that capacity; Prebid.org lists 21 providers (Prebid.org).
