Membrane

Membrane provides integration infrastructure that lets software products, internal tools and AI agents connect to third-party applications through a single interface. Rather than requiring engineering teams to hand-build each connector, Membrane's AI agent generates production-ready integration code from a plain-language description of the desired use case, choosing API calls, field mappings and data structures, while the platform's engine handles authentication (OAuth flows, API keys, token refresh), action execution and observability. The company states the resulting code is owned and controlled by the customer, positioning the product against both traditional iPaaS tools and unified-API vendors.

The platform is exposed through multiple surfaces so teams can integrate in the way they prefer: REST API, CLI, SDK, agent "skills", an MCP server, an embedded UI and a web console. Its knowledge layer, marketed as "Membrane Universe," covers what the company describes as 100,000+ apps and includes production-tested endpoints, verified auth flows, validated schemas and mapped rate limits, with self-updating detection of API changes and connector adaptation. Advertised counts include 14,200+ endpoints discovered, 8,740 auth flows verified, 42,300+ schemas validated and 6,120 rate limits mapped.

Enterprise capabilities include deployment in the customer's own cloud, VPC or data center, SOC 2 Type II certification and GDPR compliance, real-time monitoring and alerting, custom connectors, configurable rate limits and per-tenant connector variants. Higher tiers add data collections, events, flows, field mappings and universal integrations.

Business model

Membrane sells its integration platform to software and AI product teams on a tiered subscription plus usage model, with self-serve entry and enterprise agreements that include support, SLAs and on-premises deployment options.

Tiered plans with usage-based components. The Membrane Core tier is free to start with no credit card required, including unlimited integrations, access to the Membrane Agent, managed authentication, actions and monitoring, 20 AI credits per month and 20,000 action runs per month; additional action runs cost $1 per 1,000 and additional AI credits $1 each, billed monthly with no platform fee or annual commitment. The Business plan is $3,000 per month as a platform and support fee plus a per-active-customer usage fee that is capped, and includes advanced features such as data collections, events, flows, field mappings, universal integrations, 200 AI credits per month, real-time support with SLAs and an on-prem add-on. An Enterprise plan is also offered.

Traction

The company names customers including Dialpad, PandaDoc, Storyblok, Bridgestone, Constant Contact, Robin AI, Hireology, RemotePass, Sequence, Whalesync, Sembly AI, Glyphic, Contentoo, White Label Loyalty and Findymail, publishing named testimonials from engineering and product leaders at those companies. Its public GitHub organization hosts 28 repositories, the most starred being an MCP server (38 stars).
