E2X vs Liveblocks: Which Is Better in 2026?

E2X is a Model-as-a-Service API platform for AI video generation, image generation, and related media models. It is built for developers and product teams that want to add media generation to their own applications without integrating each model separately. Teams load prepaid credits, create an API key, and make requests to supported models through a single API surface and a consistent request shape.

The model catalog provides the currently available models and their per-request prices before a call. A team can compare the supported options, estimate the cost of a workflow, and choose a model suited to its needs before generating. The catalog includes models from upstream providers such as Google, OpenAI, and ByteDance; availability may change as providers and supported models change, so current catalog details are the source of truth.

E2X uses prepaid, pay-as-you-go pricing. Credits are applied to requests, and published prices are shown per request; there are no recurring subscriptions, seat charges, or commitments. This makes it possible for teams to add a generation feature while keeping platform costs tied to actual usage rather than paying for a fixed number of seats. If a job fails, the request can be reviewed for credit where appropriate.

For example, a product team can build a creative workflow that accepts a prompt, routes a video or image generation request to a supported model, and returns the result to its users. The team can use one API key and a familiar request format while evaluating different models for quality, speed, and cost. The same account can support different media features in one application, without maintaining separate billing arrangements for each upstream provider.

E2X is a developer-facing API, not an autonomous agent or a consumer image editor. Its role is to provide a consistent way to access supported AI media models, with clear per-request pricing and prepaid usage. It is suited to builders who want to make video and image generation part of an app or service while keeping integration and billing straightforward.

Teams can start with one media workflow and expand to others as their product needs change. Supported models and per-request prices are presented together in the catalog, making it easier for developers to evaluate options before integration and keep the request path consistent when they change models. This is useful for applications where users create assets on demand and usage can vary from session to session.

Liveblocks is a platform that provides ready-made infrastructure for adding real-time collaboration features to applications — things like multiplayer presence, live cursors, comments, notifications and collaborative editing. Building these "Figma-style" or "Google Docs-style" collaborative experiences from scratch is extraordinarily hard, requiring deep expertise in real-time synchronization, conflict resolution and scalable infrastructure. Liveblocks abstracts all of that away, letting developers add polished collaboration to their products in days rather than months.

The platform offers a set of building blocks for the common ingredients of collaborative software. Presence shows who else is in a document and what they're doing; live cursors and selections make collaboration feel alive; a comments and threads system lets users discuss content in context; notifications keep people informed; and collaborative editing primitives handle the hard problem of multiple people editing the same data simultaneously without conflicts. These come as APIs, SDKs and even pre-built UI components, so teams can integrate as much or as little as they need into their existing tech stack.

This makes Liveblocks valuable for any product that benefits from collaboration — which, increasingly, is most software, as users now expect the multiplayer, real-time experiences popularized by tools like Figma, Notion and Google Docs. Developers use it to add collaboration to editors, design tools, dashboards, documents, whiteboards and countless other applications, dramatically accelerating what would otherwise be a daunting engineering effort. By handling the complex, scalable real-time infrastructure and providing thoughtful, customizable building blocks, Liveblocks lets teams focus on their product rather than on solving distributed systems problems. As collaborative, real-time experiences become a baseline expectation, infrastructure that makes them attainable is genuinely important. For developers who want to add real-time collaboration to their products without building it from the ground up, Liveblocks offers a powerful, comprehensive and well-crafted solution.
