Overview

Nango provides infrastructure for building and operating integrations between products or AI agents and external APIs. It suits teams that want to own integration logic as code while relying on managed authentication and runtime operations. Its broad API coverage and deployment options are compelling, though the free plan’s hard caps and lack of EU-hosted cloud may rule it out for some teams.

Key features

Nango supports authentication, AI agent tools, webhooks, triggers, and managed incremental data syncs. Its catalog covers more than 1,000 APIs, with prebuilt tooling for authorization, pagination, rate limits, and webhooks. That breadth can reduce the work of handling common integration mechanics, but teams should still expect to build and maintain their integration logic.

Integrations are built as code, with local development, CI/CD, and multiple environments supported. Authentication methods include OAuth 2.0, OAuth 1.0a, API keys, JWT, Basic auth, and MCP auth. Nango manages token refresh and encrypts credentials in transit and at rest, with tenant isolation.

Runtime features include resumable executions, retries, rate-limit handling, logs, metrics, and alerts. These are useful operational safeguards for integrations that need ongoing maintenance rather than one-off data movement. Custom connectors are supported, and the auth UI can be branded or customized; bringing a team’s own OAuth app enables a fully white-label experience.

Pricing

The Free plan is free and includes 10 connections, 10 hours of compute per month, and 10GB of data transfer per month. Those hard-capped monthly limits make it suitable for evaluation or small workloads, but they leave little room for growth without moving to paid usage.

Pay-as-you-go costs 50.00 USD per month, billed $50 /mo, and includes $50 in monthly credits. Usage rates are $0.29/connection, $0.72/hour compute, and $0.5/GB data transfer. The credit helps offset metered usage, while teams with variable or expanding workloads should account for the connection, compute, and transfer charges rather than treating the monthly fee as an unlimited plan. Free and pay-as-you-go customers receive in-app chat support from Nango engineers.

Enterprise has custom pricing, with discounts for commitments and options for self-hosting, an MSA, and an SLA. It is the relevant tier for organizations that need those commercial or deployment terms; Enterprise customers receive a private Slack Connect channel with Nango engineers. The plans and limits make the main trade-off clear: free access is tightly bounded, while paid usage scales through metered charges.

Platforms

Nango is available as an API, web platform, and self-hosted deployment. Enterprise BYOC instances can run in AWS, GCP, or Azure regions, but Nango does not currently offer an EU-hosted cloud. Teams with EU hosting requirements should consider whether BYOC meets their needs before choosing the managed service.

The pricing page lists SOC 2 Type II certification; Nango’s auth page lists SOC 2, GDPR, and HIPAA compliance. Those credentials may matter to security reviews, but they do not remove the need to assess a deployment against a team’s own requirements.

Who it's for

Nango is a strong fit for product and platform teams building API integrations in code, especially when they need broad connector coverage, managed credential handling, and runtime visibility. Its support for custom connectors and white-label authentication also serves teams embedding integrations into their own products.

It is less suitable for teams that want a fully managed, non-code workflow builder, need EU-hosted cloud without BYOC, or expect to exceed the free tier’s caps while avoiding usage-based charges. The code-first approach is a feature for teams that want control, not a shortcut around owning integration behavior.

Pros and cons

Pros: More than 1,000 supported APIs and prebuilt tooling for authorization, pagination, rate limits, and webhooks help cover common integration needs.
Pros: Multiple authentication methods, managed token refresh, encryption, and tenant isolation centralize important credential operations.
Pros: Code-based development, custom connectors, CI/CD support, and operational runtime features suit teams that need control over integration logic and its lifecycle.
Cons: The Free plan is capped at 10 connections, 10 compute hours, and 10GB transfer per month, limiting sustained or larger workloads.
Cons: Pay-as-you-go adds metered connection, compute, and transfer charges, so costs can rise with usage.
Cons: There is no EU-hosted cloud offering, which complicates selection for teams that require that hosting location.

Alternatives

For a broader comparison, see API Integration Platforms and Integration Platform as a Service Software.

Knit is worth considering if its Android and iOS platform coverage or its 100K API calls/month Start Up plan at 499.00 USD per month better matches a mobile-oriented integration workload.
Google Cloud Application Integration may suit teams that want a free tier with up to 400 integration executions and up to 20 GiB of data processed per month.
Windmill is an option for teams seeking a free and open-source platform with self-hosted support and a free tier that includes 3 workspaces and 50 users.
Workato Agent Studio offers a no-cost plan with 50,000 one-time credits and AI and agentic capabilities, which may fit teams prioritizing those capabilities.
Apache NiFi is a free alternative for teams seeking downloadable, self-hosted software under the Apache License, Version 2.0.
Oracle Integration is another API and web platform, with Standard and Enterprise plans that each specify 5,000 messages per hour.
Boomi may be relevant to teams considering a paid platform with a 30-day free trial and a Pay-As-You-Go plan priced at 99.00 USD per month plus usage.
Tray.ai is another paid API and web option with Pro and Team plans.

Verdict

Choose Nango if your team wants code-owned integrations backed by broad API coverage, managed authentication, and practical runtime operations. Its strongest case is the combination of developer control and managed integration infrastructure. Look elsewhere if EU-hosted cloud is mandatory, if you need a non-code builder, or if the monthly caps and metered usage do not fit your workload.
