Nango is the best pick for most code-first teams that want deep integrations, while Merge is the best pick when you need one shared schema for HR, ATS, CRM and accounting data. One fact that changes the maths is that Merge counts one customer with three integrations as three linked accounts, so 30 linked accounts cost $1,950 per month on Launch, at $650 for the first 10 plus $65 for each account after 10. Nango starts at $50 per month for its Pay-as-you-go plan, Composio starts at $18 per seat per month for Standard, and Knit starts at $499 per month, while Paragon and Prismatic do not show a dollar price on their pricing pages.
Nango gives code-first teams auth, syncs, webhooks and tool calls across 1,200 plus APIs, with usage meters for connections, compute time and data transfer. Deep integrations need custom fields, write access, change events, per-customer settings and clear logs when a sync fails. The eight options below cover that deeper work in different ways, and each price comes from the official pricing page opened on 2026-11-12.

The 8 best nango alternatives for deep integrations, in detail
Nango
Best for: code-first teams that want full control
Nango is the named product in this topic, and it stays in the list because it is a real option for teams that want to write integrations as code. The Free plan costs $0 per month and covers API and MCP auth, tools and syncs, with hard-capped limits that reset monthly. The Pay-as-you-go plan costs $50 per month and includes $50 in credits each month.
- Usage rates are $0.29 per connection, $0.72 per compute hour and $0.50 per GB of data transfer, so a team with many connections and heavy syncs will s
- Choose Nango when your engineers want to own the integration code, extend pre-built templates, or run Nango in your own cloud on Enterprise.
- Do not choose Nango when you want a shared schema already mapped for HR, ATS or accounting, because that work still sits with your team.
Pros
- Free plan covers 10 connections, 10 compute hours and 10 GB per month
- source-available code and self-hosting on Enterprise
Cons
- Usage meters for connections, compute and transfer can be hard to forecast
- Growth add-on costs $450 per month
Merge
Best for: B2B SaaS teams that need one schema for HR, ATS and accounting
Merge gives your product one endpoint for HRIS, ATS, CRM, accounting, ticketing, file storage and knowledge base data, with a common model for each category. Launch starts free for your first 3 production linked accounts, then costs $650 per month for up to 10 total production linked accounts, with $65 per linked account after 10. One customer with three integrations counts as three linked accounts, and 30 linked accounts cost $1,950 per month on Launch.
- Professional and Enterprise use contract-based pricing.
- Choose Merge when a shared schema matters more than custom code, and skip it when most customers connect many integrations each.
Pros
- First 3 production linked accounts free
- Professional adds custom fields and custom sync frequencies
Cons
- Each extra linked account costs $65 per month after 10
- Launch sync is daily, not real time
Paragon
Best for: SaaS teams that want embedded workflows plus agent actions
Paragon is an embedded integration platform with three products on one platform: Managed Sync, ActionKit and Workflows. Managed Sync runs ingestion pipelines for high-volume data, with normalized schemas that can be customized. ActionKit gives one API and MCP server for hundreds of synchronous integration actions.
- Workflows lets teams author integration logic in TypeScript or a low-code editor.
- The pricing page shows Platform and Enterprise plans, with no dollar price on either plan, so the starting price here is quote only.
- Usage costs scale with Connected Users, which means the customer organisations in your product that use integrations.
- Do not choose it when you need a published price before a sales call.
Pros
- Managed Sync, ActionKit and Workflows on every plan
- sync frequencies up to every minute
Cons
- No dollar price on the pricing page
- usage scales with Connected Users, so cost rises with adoption
Apideck
Best for: teams that want clear consumer pricing and pass-through data
Apideck is a unified API that reads and writes data in real time through a pass-through layer, rather than keeping a synced copy of customer records. Launch costs $599 per month, billed monthly, for 25 active consumers and 1 unified API category, with passthrough, webhook support, MCP server and standard support. The price per consumer falls from $23.96 at 25 consumers to $8.50 at 500 consumers on Scale.
- Choose Apideck when you want published prices, a real-time model and a clear consumer meter.
- Do not choose Launch when you need two or more categories at once, because that forces a move to Scale.
Pros
- Launch includes passthrough, webhooks and MCP server
- no stored copy of customer records in the pass-through layer
Cons
- Launch covers only 1 unified API category
- Scale at $1,299 per month is needed for 3 categories
Unified.to
Best for: teams that want usage-based pricing with unlimited connections
Unified.to is a real-time unified API across 38 plus categories and 2,221 plus integrations, with no customer records stored in the integration layer. Grow costs $750 plus per month for 750,000 monthly API calls, with overage at $1.00 per 1,000 calls, unlimited customers, unlimited connections, virtual webhooks and 2 monthly support hours. Scale costs $3,000 plus per month for 6,000,000 calls, with overage at $0.50 per 1,000 calls.
- The Test plan costs $0 per month for 30 days in non-production use, with 10,000 monthly API calls and 500 calls per minute.
- Log retention is 30 days on Test and 60 days on Grow and Pro, rising to 365 plus days on Scale.
- Choose Unified.to when call volume, not customer count, should set the bill.
- Do not choose Grow when you need more than 750,000 calls a month or more than 2 support hours.
Pros
- Unlimited customers and connections on Grow
- overage is $1.00 per 1,000 calls on Grow
Cons
- Grow includes only 2 monthly support hours
- Pro at $1,500 per month is needed for 2,000,000 calls
Prismatic
Best for: B2B SaaS teams that need per-customer integration instances
Prismatic is an embedded integration platform built for B2B SaaS companies that ship integrations inside their own product. An integration is a reusable workflow, and an instance is one deployment of that integration to one customer, so seven integrations for one customer count as seven instances, and one integration for seven customers also counts as seven instances. Pricing is based on a platform subscription plus active instances, and the pricing page states that plans are never billed on API calls or executions.
- Scale, Enterprise and Custom plans all end in a demo request on the pricing page, so the starting price here is quote only.
- Choose Prismatic when each customer needs its own configuration, credentials and monitoring for the same integration.
- Do not choose it when you need a published price, because the rate is set in the contract.
Pros
- Pricing is based on platform subscription plus active instances, not API calls
- low-code and code-first tools in one platform
Cons
- No dollar price on the pricing page
- instance count grows with customers times integrations per customer

The Free plan costs $0, with no credit card required, $2 in credits one time, up to 3 members, 10,000 tool calls per month and up to 3 custom MCP servers. Standard costs $18 per seat per month, with $18 in credits per seat every month, 10,000 tool calls per month per seat and any number of custom MCP servers.

- Choose Composio when agents need ready tools fast, with a free tier that has a hard cap.

- Standard includes $18 in credits per seat each month

- Free plan is capped at 10,000 tool calls per month

Connected accounts are contract based on every plan, and the price depends on the volume of integrated accounts.

Pros
- Start Up includes 100,000 API calls per month and all whitelisted connectors
- 30-day trial before billing starts

How we chose
We chose products that offer deep integrations, not only a single connection, and we checked each one against the same test: a real product with an official pricing page opened on 2026-11-12, a named billing meter, a stated sync or call limit, and a clear free plan or trial status. Prices and plan limits in this article come from official vendor pricing pages opened on 2026-11-12, and quote only means the vendor showed no dollar price on that page. We did not test any tool hands-on. The unique angle is the billing meter, because each vendor meters a different unit, from linked accounts and API calls to instances and tool calls.

Merge bills per linked account, where one linked account is one customer connection to one integration, so one customer with three integrations counts as three linked accounts.
