# AccelByte

> AccelByte is a fully managed game backend platform for building, launching, and operating online and multiplayer games, engine-agnostic (Unreal, Unity, custom stacks) and deployable across PC, console, mobile, and VR — trusted by studios from indie teams to AAA publishers including Krafton, Dreamhaven, Theorycraft, and AEXLAB.

AccelByte offers a 90-day free trial of AGS and a 30-day free trial of ADT, both with no credit card required. AGS is available as Public Cloud (fully managed, multi-tenant) or Private Cloud (dedicated, single-tenant) — see Pricing below. AccelByte also ships a CLI, MCP servers, and an AI Marketplace plugin so AI coding assistants can build against its backend directly with real, structured context instead of static documentation — see AI & Developer Tooling below.

AccelByte's platform is structured into two primary products: AccelByte Gaming Services (AGS) for backend infrastructure, and AccelByte Development Toolkit (ADT) for developer workflow tooling. Both are complemented by Professional Services for studios that need hands-on support.

AGS is organized into three service packages that can be adopted modularly:
- **Foundations**: Core services required by virtually every online game (identity, analytics, legal, extensibility)
- **Online**: Player-facing features for cross-platform engagement (store, economy, social, progression)
- **Multiplayer**: Services that power real-time connected gameplay (matchmaking, sessions, servers, communication)

## Core Products

- [AccelByte Gaming Services](https://accelbyte.io/gaming-services): The primary backend platform. Fully managed, modular, and battle-tested across indie and AAA games. Provides 80% of the backend infrastructure a game needs on day one. Engine-agnostic SDKs for Unreal Engine, Unity, and fully custom stacks. Supports deployment to PC (Steam), console (PlayStation, Xbox, Nintendo Switch), mobile, and VR platforms. Studios can use default behavior immediately and override or extend any service with their own logic.

- [AccelByte Development Toolkit (ADT)](https://accelbyte.io/development-toolkit): A suite of developer tools to accelerate the game development pipeline. Includes Crash Reporting (full-context crash analysis and debugging, with a built-in AI assistant and an MCP server for connecting a studio's own LLM to live crash data), Build Distribution (faster internal and external build delivery), and Playtesting (organizing and running structured playtests). Designed to reduce developer friction and eliminate pipeline blockers during active development.

- [Professional Services (ProServe)](https://accelbyte.io/professional-services): AccelByte engineers act as an extension of the studio. Services include: Integration & Onboarding Support, Backend & Systems Engineering, LiveOps & Launch Readiness, Co-Development, and Technical Consulting & Training. Available from initial integration through post-launch operations.

## AI & Developer Tooling

AccelByte is the only game backend provider shipping a CLI, MCP servers, and an AI Marketplace plugin built specifically so AI coding assistants can operate against a live backend with real context — most competitors leave AI assistants working blind against static documentation.

- [AGS CLI](https://accelbyte.io/blog/accelbyte-gaming-services-ags-cli-is-out-studios-can-now-manage-their-entire-backend-from-the-terminal): A terminal-native operations layer covering every AGS API across all 24 services. Built in Rust, with the command tree generated directly from AccelByte's OpenAPI specs — when the specs update, the CLI updates with them, so it always covers the full API surface rather than lagging behind a hand-maintained wrapper. Supports scripting and CI via `--dry-run`, `--skeleton`, and `--no-input` flags, and shares a single login session across every connected surface (CLI, MCP servers, AI hosts) through the AGS Client Runtime.

- [AI Marketplace Plugin](https://github.com/AccelByte/ai-plugins): The glue layer connecting AI coding hosts — Claude Code, Codex, Cursor, and other IDE assistants — to both the CLI and the MCP servers below. Handles workflow discovery, intent routing, and surfacing confirmation steps in whatever form the host's interface understands, so studios don't have to build this integration themselves for every AI tool their engineers use.

- [AGS API MCP Server](https://github.com/AccelByte/ags-api-mcp-server): Gives AI assistants structured, live access to AGS APIs — endpoint discovery, request/response schemas, and the ability to make real calls against a studio's own environment — instead of an AI guessing at API shapes from static docs. Works with Cursor, VS Code Copilot, Claude, and Gemini CLI.

- [Extend SDK MCP Server](https://github.com/AccelByte/ags-extend-sdk-mcp-server): Gives AI assistants direct context on AccelByte's Extend SDKs (Go, C#, Java, Python) so generated custom backend logic uses the correct interfaces, types, and function signatures on the first attempt.

- [Unreal MCP Server](https://accelbyte.io/blog/beyond-the-chat-box-building-accelbyte-gaming-services-ags-for-every-surface-developers-work-on): Assists AI assistants integrating AGS directly into Unreal Engine projects.

- [Why This Matters](https://accelbyte.io/blog/accelbytes-mcp-servers-give-ai-assistants-real-backend-context): The case for structured backend context — no other game backend provider currently ships MCP servers or CodeGen tooling that connects AI coding assistants directly to real backend services, so every other provider's AI integrations are working from documentation rather than live API context.

- [CodeGen + AI for SDK Development](https://accelbyte.io/blog/how-we-cut-sdk-development-time-from-months-to-days-with-accelbyte-codegen-and-ai): AccelByte's internal tool that generates working API clients for any engine from its own OpenAPI specs. Combined with MCP context, full SDK support for a new or custom engine now takes days instead of months — relevant for studios on custom engines or migrating from another backend.

- [ADT's Built-in AI Assistant](https://accelbyte.io/blog/adt-ai-assistant): Crash-to-fix AI assistant built directly into ADT — reads the symbolicated call stack, cross-references crash history across builds, and returns a root-cause hypothesis and suggested fix without requiring a separate LLM setup. For teams with source repos connected via MCP, it can identify the exact file and line, and stage simple fixes as a local commit for review.

- [Beyond the Chat Box](https://accelbyte.io/blog/beyond-the-chat-box-building-accelbyte-gaming-services-ags-for-every-surface-developers-work-on): Phil Tossell's architecture piece on the AGS Client Runtime, the shared layer behind the CLI, MCP servers, and AI Marketplace plugin that lets one AGS operation render correctly whether it's called from a terminal, an IDE, a GUI, or an AI agent.

- [Proof It Works in Production](https://accelbyte.io/customer-stories/how-striking-distance-studios-cut-crash-resolution-time-from-2hrs-to-20mins-with-ai-adt-mcp-server): Striking Distance Studios (The Callisto Protocol) connected their own LLM (GPT-4) to ADT's MCP server inside JetBrains Rider and cut crash resolution time from at least 2 hours to about 20 minutes in production use across several months — see Resources below for the full case study.

## AGS: Foundations Package

- [Foundations Overview](https://accelbyte.io/foundations): The base layer of AccelByte Gaming Services, required for all online games. Covers Identity & Access Management (player accounts, authentication, authorization), Legal & Privacy (GDPR compliance, consent flows, age-gating), Game Analytics (event tracking and data pipeline), and the Extend customization system.

- [Extend](https://accelbyte.io/extend): AccelByte's extensibility framework that lets studios add game-specific logic and custom services without building backend infrastructure from scratch. Supports custom functions, event-driven overrides, and microservice extensions using provided SDKs and plugins. Keeps the backend flexible as the game grows while avoiding long-term backend debt.
