Today we’re excited to launch coherence 2.0, the next major release of our multiplayer engine and hosting platform. Built from years of real production work (including powering the flawless online multiplayer launch of Vampire Survivors) coherence 2.0 brings three major upgrades that make multiplayer development more accessible, more flexible, and more affordable for every Unity team.
This release represents a real shift in what multiplayer development can look like: a production-proven networking engine that feels native to Unity, hosting options that work for any project and any budget, and a pricing model designed to empower developers instead of limiting them.
Whether you're an indie building multiplayer for the first time or a studio shipping at scale, coherence 2.0 gives you the tools and freedom to create great real-time multiplayer experiences with less risk and more control.
Multiplayer development has always been complicated, expensive, and unpredictable. Traditional networking solutions force teams to compromise, often having rigid hosting requirements, heavy upfront costs, or deep networking expertise.
coherence was built to change that.
With version 2.0, we’re delivering a single multiplayer engine that brings together:
Each part reinforces the same idea: multiplayer shouldn’t be harder or riskier than it needs to be. coherence 2.0 is our biggest step yet toward giving every game developer the ability to build and ship multiplayer confidently, regardless of team size.
The foundation of coherence 2.0 is a multiplayer engine that has been tested and hardened in real commercial environments. Over years of live development with studios across multiple genres and platforms, coherence has evolved from a promising SDK into a dependable, scalable multiplayer platform that developers can trust.
Hardened through real-world production Every major version of coherence leading up to 2.0 brought improvements:
This is the same technology our internal engineering team uses to build bespoke multiplayer solutions for clients. Most notably, it’s the tech that powered Vampire Survivors’ online multiplayer launch. We helped transform it from a local co-op game to fully online play, delivered without disruption to millions of players.
Designed so generalist Unity developers can succeed coherence 2.0 reduces the traditional networking curve dramatically. Developers can:
Even Unity generalists with no networking background can begin adding multiplayer features quickly.
With coherence 2.0, every improvement works toward the same goal: multiplayer that feels intuitive, stable, and trustworthy. Not a mysterious, fragile black box.
Every multiplayer game has different needs. Some require the control of self-hosted servers. Others want the simplicity of managed cloud hosting. Many need the affordability of client-hosted (serverless) sessions.
Most teams, though, want the flexibility to adapt their hosting model as their game grows.
coherence 2.0 makes that possible, through three hosting models, so developers can choose their ideal deployment path:
coherence Cloud Hosting A managed, auto-scaling infrastructure where teams pay only for the resources their game actually uses.
coherence Client Hosting A modern approach to serverless hosting where the game client can host the session. Reliable, efficient, and perfect for keeping costs extremely low at launch.
Self-Hosting Full control for teams running their own servers: on-premesis, other cloud providers, or hybrid setups.
Mix and match your hosting, or switch at any time One of the biggest strengths of coherence is that you don’t need to commit to a single hosting path forever.
You can:
…and switch between them without rewriting game logic.
This flexibility was proven during the Vampire Survivors launch, where Poncle was able to transition between Client Hosting and coherence Cloud Hosting at launch to keep players online during unexpected platform issues. They had full control, and zero downtime for players.
This is the biggest overhaul we’ve ever made to our business model and it’s entirely built around reducing risk and increasing accessibility for any developer.
We want more developers making multiplayer games. To do that, pricing needs to be predictable, fair, and aligned with developer success.
coherence 2.0 introduces two subscription tiers:
Starter Tier
→ Free for studios under $200K annual revenue or funding
→ Full access to the SDK, network engine, and dashboard
→ No CCU limits, no project limits, and free starter cloud credits for testing
Pro Tier
→ A simple $1,000/month studio license
→ Predictable costs for established teams
→ Extra onboarding support
→ More free starter cloud credits for testing at larger scale
There are no hidden usage fees, no gating features behind expensive enterprise plans, and no paywalls preventing teams from learning or experimenting.
Affordable, flexible hosting Hosting follows one simple rule: pay only when your game succeeds or uses cloud resources.
If a game drops below the threshold, developers stop paying.
This model is truly aligned with developers, and not linked to time, CCU, or lock-in tactics. We want to empower indies, support experimental teams, and stay affordable successful games scale.
coherence 2.0 is a major milestone. It unifies years of production improvements into a single, reliable, flexible multiplayer engine that teams of any size can use.
It proves that multiplayer doesn’t need to be complicated or expensive. It shows that hosting doesn’t need to lock you in. It makes multiplayer development possible for far more teams.
Most importantly, it carries forward the coherence mission: connect people through play.
