Arc0 vs Nango.
Considering Arc0 as a Nango alternative? A like-for-like read on pricing, branding, tokens, open source and self-hosting, and syncs, including where Nango is still the better choice.
Arc0 and Nango, line by line.
| Item | ARC0 | NANGO |
|---|---|---|
| Pricing unit | Per active user; 5,000 calls/user/mo pooled across the workspace, then $0.25 per 1,000 calls | Per connection ($0.29/connection/month on pay-as-you-go), plus separately metered compute time and data transfer |
| Entry pricing | Build: free for up to 100 active users in production; Launch: $99/mo including 1,000 active users | Free: 10 connections, 10 compute hours and 10GB transfer per month; Pay-as-you-go: $50/mo base plus usage |
| Your users' consent screen | Customer's logo on every plan; on paid plans it can run on the customer's own domain with the customer's own OAuth apps | Nango's name is omitted from the auth flow on every plan; matching your brand's colors and logo, and removing "Secured by Nango," requires Enterprise |
| Catalog | 1,500+ apps; vendors' official MCP servers can sit behind Arc0 auth | 1,000+ APIs and MCP servers, with 7,000+ pre-built tools, triggers and syncs already built for them |
| Token export | Exportable at any time by API; tokens from the customer's own OAuth apps keep working after export | Retrievable at any time via the Get Connection API; connections made with your own ("self-managed") OAuth app, available on every plan, stay under your control |
| Audit log | Every call logged on every plan including free; retention 7 days on Personal, 30 on Build, 90 on Launch; OpenTelemetry export on paid plans | Integration logs on every plan including free; a separate account-level audit trail is Enterprise-only; OpenTelemetry export needs the $450/mo Growth add-on or Enterprise |
| Deployment / self-host | No self-host; the Scale plan adds dedicated and EU-region hosting on Arc0's own infrastructure | A free limited self-host option (auth and proxy only) for hobby use; full self-host or BYOC in your own AWS/GCP/Azure account requires Enterprise; no EU-hosted cloud offered directly |
| Open source | Hosted service; not open source | Source-available under the Elastic License 2.0 (you can self-host it; you can't resell it as a competing hosted service) |
Where Nango is the better choice.
The open-source core can be self-hosted for free for hobby projects (auth and proxy only), and Enterprise adds fully supported self-hosting or BYOC in your own AWS, GCP or Azure account. Arc0 runs only on its own infrastructure, including its Scale-plan dedicated and EU hosting.
Nango ships 7,000+ pre-built tools, triggers and two-way syncs across 1,000+ APIs, plus custom sync and action functions you deploy yourself. Arc0's catalog today covers auth and a call proxy; triggers and webhooks are still on its roadmap.
Nango has been building API integration infrastructure with a public open-source repo (12,400+ GitHub stars) and named enterprise customers for several years. Arc0 is newer and narrower in scope, focused only on agent connectivity.
What Arc0 does differently.
Nango charges per connection plus separately metered compute time and data transfer. Arc0 charges per active user with a pooled monthly call allowance included.
Nango's auth flow omits its own name on every plan, but matching your brand's colors and logo and removing "Secured by Nango" requires Enterprise. Arc0 puts the customer's logo on every plan, including free.
Arc0 holds SOC 2 Type II with the report available on request, is GDPR compliant and signs a DPA, and its Scale plan adds dedicated and EU-region hosting. Nango's SOC 2 Type II applies from its $50/mo paid plan up (not on Free), and it has no EU-hosted cloud, offering EU deployment only through Enterprise BYOC in a customer's own cloud account.
Nango's per-call "Logs" are on every plan, but its account-level audit trail is Enterprise-only, and OpenTelemetry export costs an extra $450/mo Growth add-on (or Enterprise). Arc0 logs every call on every plan including free, with OpenTelemetry export on any paid plan.
Nango is source-available under the Elastic License 2.0, which lets you self-host but not resell it as a competing hosted service. Arc0 is a hosted service and its code is not open source.
Nango counts 1,000+ APIs and MCP servers with 7,000+ pre-built tools and syncs already built for them. Arc0 counts 1,500+ apps and lets vendors' own official MCP servers sit behind Arc0 auth.
Free migration from Nango.
An engineer moves you over at no charge, on any plan. You keep shipping while we do the work, and nothing changes for your users until you say so.
- 01We map itEvery app, action and auth config your agent uses in Nango, matched to Arc0.
- 02We set it upYour OAuth apps registered, Arc0 Connect in your brand, and your first policies written with you.
- 03We move your usersTokens imported wherever Nango lets you export them, and reconnects staged in-product where it doesn’t.
What moving from Nango looks like.
Moving from Nango to Arc0 mostly touches the credential and consent layer, since both sit outside your app as a service your code calls through an SDK, API, or MCP endpoint.
Connections
Yes, with a caveat. Nango's Get Connection API returns live credentials for any connection at any time. If you registered your own OAuth app under Nango's "self-managed apps" option, that app registration and its tokens are already yours and keep working with no user action. If you used one of Nango's own shared OAuth apps, users reconnect once through Arc0's branded flow instead.
Your agent
Point agents at the Arc0 MCP endpoint, SDK, or REST proxy in place of Nango's MCP server or request proxy. Each user's access stays limited to what they approved during consent, the same model Nango uses today.
Questions, answered.
Is Arc0 a good Nango alternative?
Yes if you want an agent-focused connectivity layer with per-user pricing and a branded consent screen on every plan, and you don't need Nango's two-way syncs, custom sync or action functions, or self-hosting. If you depend on Nango's sync engine, its self-host/BYOC options, or the depth of its 7,000+ pre-built integrations, Nango remains the better fit today.
Does Nango cost more or less than Arc0?
It depends on the shape of your usage. Nango's $0.29/connection plus metered compute and data transfer can cost more for high-call, low-connection workloads, while Arc0's per-user pricing with a pooled 5,000 calls/user can cost more if most users need very few calls. Run both models against your own connection count and call volume before deciding.
Can I self-host Arc0 the way I can with Nango?
Not today. Arc0 has no self-host or VPC option; its Scale plan adds dedicated and EU-region hosting on Arc0's own infrastructure. Nango can be self-hosted for free for hobby projects (auth and proxy only), or with full support and BYOC on its Enterprise plan.
Is Nango open source?
Nango's core is source-available under the Elastic License 2.0: you can read, self-host and modify it, but you can't resell it as a competing hosted service. Arc0 is a hosted service and its code is not open source.
