Our verdict
LangDB suits teams that want a single gateway across a very wide provider list: it routes from 250 providers and lets you bring your own key, with a free tier to start. Fees follow Subscription plans plus usage-based model credits, so the subscription and the metered model credits sit on the same bill.

Pros and cons
Pros
- Broad provider coverage: from 250 providers routed, well above the 9 median across the gateways compared here.
- Bring your own key is supported, and Subscription plans plus usage-based model credits keeps the gateway charge distinct from provider billing.
- An OpenAI-compatible API keeps most existing integrations working with little change.
- A free tier lets a small team run real traffic before choosing a subscription.
Cons
- Support runs on email, help centre and community, so a live incident depends on email and the help centre rather than a real-time channel.
- Two moving parts sit in Subscription plans plus usage-based model credits, which is harder to forecast than a single flat choice such as Flat monthly subscription or pay per token.
Who it suits
- Teams that want a single gateway in front of from 250 providers and the option to keep their own keys.
- Developers testing a gateway on a free tier before committing to a subscription.
- Teams that prefer Subscription plans plus usage-based model credits to running and maintaining their own gateway.
Who should look elsewhere
- Buyers who want to own and self-host the gateway: LiteLLM runs free under an MIT licence, with paid enterprise work sold as an annual licence.
- Shoppers who want a single predictable charge, since Salad's Flat monthly subscription or pay per token is a simpler billing shape.
Core features
LangDB sits at the wide end of gateway coverage, routing from 250 providers through a single place. Bring your own key is supported, so teams can keep keys under their own provider accounts. The API is OpenAI-compatible, which keeps client changes small when you move traffic between models or providers.
The company behind it
LangDB is operated by Dozer Data Pte Ltd, with its headquarters in Singapore. That entity is the party behind the pricing and the terms, which matters for procurement and data processing questions. Support is handled through email, help centre and community, so most queries land in email or the help centre, with a community channel alongside.

Frequently asked questions
What does LangDB charge?+
Billing follows Subscription plans plus usage-based model credits. A subscription covers the gateway, and model credits are metered as traffic runs through it, so the two charges scale differently. A free tier is available for teams that want to test routing before choosing a plan.
Is there a free tier?+
Yes, a free tier comes with Subscription plans plus usage-based model credits. It is the practical way to check routing, reporting and cost tracking on real prompts before any spend. Most gateways in this group also offer one, so the reason to pick LangDB is breadth: from 250 providers behind a single endpoint.
Can I bring my own provider keys?+
Bring your own key is supported, so keys stay in the provider accounts you already manage. LangDB handles routing and the OpenAI-compatible surface on top, and Subscription plans plus usage-based model credits covers the gateway layer. With from 250 providers routed, switching vendors becomes a configuration change rather than an integration project.
How many providers can I route?+
LangDB routes from 250 providers, against a 9 median across the gateways compared here. That spread makes fallback practical: a backup provider is a setting away instead of a new client build, and a single vendor's quota rarely sets your ceiling.
Who runs LangDB?+
The service is operated by Dozer Data Pte Ltd, with its headquarters in Singapore. That company is the counterparty on the terms, pricing and invoices, which is the name to use in a supplier review or data processing agreement. Support is handled through email, help centre and community.
What support do I get?+
Support runs on email, help centre and community. Email carries account and billing questions, the help centre covers setup and routing, and the community channel takes usage patterns and workarounds. For an outage that needs a live answer, a gateway with a phone or chat line is the safer pick, since only 19.5% of the gateways in this group offer phone support.
How does LangDB compare with LiteLLM?+
LiteLLM self-hosts free under an MIT licence, and its paid enterprise tier is an annual licence priced on gateway request capacity. LangDB runs as a service instead: Subscription plans plus usage-based model credits, with nothing to install. Choose LangDB to avoid operating the gateway, LiteLLM to keep it in your own infrastructure.
