Key takeaways
Replicate offers one predictions API with webhooks across Veo 3.1, Kling 3.0, Seedance 2.5 and the Wan line, billed per second.
Melius suits teams building multi-model video pipelines: its API, CLI and MCP server drive the same canvas your creative team edits, with each step on the model suited to it.
The Runway API pairs Runway's Gen-4.5 with Veo 3.1, Kling 4, Seedance 2.5 and Wan 3, billed at $0.01 a credit.
No host is cheapest for every model. Seedance 2.5 at 720p costs about $0.47 a second on fal and about $0.23 on Replicate, while Kling 3.0 Pro costs twice as much on Replicate as on fal.
If you called Veo 3.1 through the Gemini API, the preview model IDs shut down on October 22, 2026, so use Vertex AI or another host.
How we ranked
You already know which models you want. The question is where else to call them and what changes when you move: the price per second, which model versions you get, how finished jobs come back, how far an account can scale and what happens to your data. We ranked hosts on the video models they offer, published per-second pricing, async jobs and webhooks, SDKs and tooling, rate limits and concurrency, enterprise terms, data retention and support for chaining models into pipelines. Prices are pay-as-you-go list prices in US dollars as of October 26, 2026.
Why teams look beyond fal.ai
fal.ai is a developer platform for generative media, with Seedance 2.5, Kling 4.0, Veo 3.1, Wan 3.0 and MiniMax models behind a queue API with webhooks and Python and JavaScript clients. Common reasons to compare alternatives:
Price on specific models. fal charges about $0.47 a second for Seedance 2.5 at 720p, roughly double ByteDance's own API rate.
Starting concurrency. Every new fal account starts at two concurrent requests, rising with what you've paid over the last four weeks.
A first-party contract, or a workspace where non-developers can work on the same generations.

1. Replicate: Best for a broad per-second catalog
Replicate is a model-hosting API where one predictions API calls a public catalog of models, including "Official" models it runs with the model makers. Cloudflare bought it in 2025, and it still runs as its own brand.
What works: Video models include Veo 3.1, Kling 3.0 and 3.0 Omni, Seedance 2.5 and Wan 2.1 through 2.7, and Official models are always on with predictable per-second pricing. Seedance 2.5 costs about $0.23 a second at 720p, about half fal's rate, and Veo 3.1 matches fal at $0.40 with audio. Predictions support webhooks, and you can deploy your own models next to the catalog.
What doesn't: Kling 3.0 Pro costs about twice fal's rate, Seedance 2.5 stops at 720p and API inputs and outputs are deleted after an hour by default, so you have to copy files out quickly.
Best for: Developers who want one API and per-second billing across many video models.
2. Melius: Best for multi-model video pipelines your team can edit
Melius is the AI-native operating system for creatives, offering AI agents for creative work on a node-based canvas that runs leading image, video and audio models.
What works: Its REST API, CLI and MCP server drive the same canvases as the web app, so a pipeline built in code, from a still to Seedance 2.5 to a voice track, can be opened, tweaked and rerun by your creative team. In the app, Mel, the Melius agent, builds the canvas from a brief and picks a model for each step, from Veo 3.1 to Kling 3.0, and Claude or ChatGPT can do the same over MCP. Every node stays editable, bulk runs execute a whole canvas in order and outputs stay saved as versions.
What doesn't: There are no webhooks or public per-second prices, and one clip takes several API calls.
Best for: Teams whose video generations are steps in a larger production that designers and producers also work on.
3. Runway API: Best for Runway's models plus third-party ones on one contract
The Runway API is Runway's developer platform, separate from its web app, serving Runway's own models alongside third-party ones.
What works: One credit balance covers Runway Gen-4.5 at 12 credits a second, plus Veo 3.1, Kling 3.0 and 4, Seedance 2.5 and 2.0 (including 4K on 2.0), Wan 3 and Hailuo 3, at $0.01 a credit. Seedance 2.5 costs $0.30 a second at 720p, and Kling 4 is discounted below its list price. Node and Python SDKs include a wait helper, and Runway publishes usage tiers that rise automatically with spend.
What doesn't: The first tier allows only one or two concurrent tasks and $100 of spend a month, and it has no webhooks; the SDK polls with a wait helper.
Best for: Runway users who want other leading video models on the same bill.
4. Runware: Best for one endpoint across a wide catalog
Runware is an inference API that puts image, video, audio, language and 3D models behind one endpoint, so switching models is a change of model ID.
What works: Its video catalog runs from Kling 2.6 to Kling 4.0, Veo 3.1 with Fast and Lite, Seedance 1.0 to 2.5, Wan 3.0 and MiniMax H3. Kling 4.0 costs about $0.133 a second, around 15% below list, and Wan 3.0 $0.05. Jobs run asynchronously over REST or WebSockets, with webhooks, TypeScript and Python SDKs, a CLI and MCP support, and output URLs last seven days by default.
What doesn't: Many video models show example costs per clip rather than a per-second rate card, and rate limits and SLA terms aren't published.
Best for: Apps that switch between many video models and want real-time connections.
5. WaveSpeedAI: Best for high request limits after a top-up
WaveSpeedAI is a pay-per-use generative media API with its own inference acceleration.
What works: The catalog covers Seedance 2.5 (including edit and extend), Kling 3.0 and 4.0, Veo 3.1 with Fast and Lite, Wan 3.0 and MiniMax H3, at prices such as $0.36 a second for Seedance 2.5 at 720p and $0.112 for Kling 3.0 Pro. Any top-up raises an account to 500 predictions a minute and 300 concurrent tasks, and a single $5,000 top-up reaches 5,000 a minute. Webhooks with signature checks, a synchronous mode and Python and JavaScript SDKs are included.
What doesn't: It lists a 4K option for Seedance 2.5, which ByteDance's specification doesn't support, and it publishes no SLA.
Best for: Apps that need to scale request volume quickly without a sales contract.
6. Google Vertex AI: Best for Veo on Google's own contract
Vertex AI, now presented as Google Cloud's Agent Platform, is Google's first-party route to Veo.
What works: Veo 3.1 costs $0.40 a second with audio at 720p or 1080p, the same as on fal, while Veo 3.1 Fast is $0.10 a second at 720p with audio against $0.15 on fal. Veo 3.1 Lite, from $0.05 a second with audio, isn't on fal at all. You get Google Cloud billing, quotas and enterprise contracts.
What doesn't: It offers Veo only, and setting up a Google Cloud project is more work than an API key.
Best for: Teams that mainly use Veo and want Google's terms and billing.
7. BytePlus ModelArk: Best for first-party Seedance outside the US
BytePlus ModelArk is ByteDance's international cloud and the official Seedance API.
What works: It runs every Seedance 2.x version, including 2.5 Draft and Seedance 2.0 at 4K, at ByteDance's own rates, about $0.23 a second for Seedance 2.5 at 720p. You're charged only for videos that generate successfully.
What doesn't: BytePlus says it isn't available in the United States, it offers Seedance only and Seedance 2.0 there doesn't accept real human faces as direct references.
Best for: Development teams outside the US that build mainly on Seedance.
8. Together AI: Best for adding video to a Together account
Together AI is an AI cloud known for language model inference, with a small video catalog.
What works: Seedance 2.5 and 2.0, Veo 3.1 and Lite, MiniMax H3, Hailuo 02, PixVerse, Vidu and Wan 2.7 run as asynchronous jobs you create and poll, with Python and TypeScript SDKs, on the same account and bill as Together's language models.
What doesn't: The catalog is small and has no Kling. Seedance 2.5 is capped at 720p, and the pricing table lists prices per video without a resolution or length for several models, so check before you budget.
Best for: Anyone already running language models on Together.
How to switch from fal.ai
Check the exact model version. Hosts carry different versions and limits; Replicate and Together stop Seedance 2.5 at 720p, while fal goes to 1080p.
Compare on the clip you make most. Price a typical clip, such as eight seconds of 1080p with audio, on each host rather than the headline rate.
Replace webhooks or plan for polling. fal, Replicate, Runware and WaveSpeedAI document webhooks; Melius and Together use polling.
Copy outputs out. Replicate deletes API outputs after an hour by default and Runware keeps URLs for seven days.
Read the model's license as well as the host's. Commercial rights usually follow the model maker's terms.
Frequently asked questions
What is the best alternative to fal.ai for video generation?
Replicate suits developers who want per-second pricing and webhooks across Veo 3.1, Kling 3.0, Seedance 2.5 and Wan. Melius suits teams building multi-model video pipelines their creative staff also edit, and the Runway API adds Runway's own Gen-4.5 to the same models.
Is fal.ai cheaper than Replicate?
It depends on the model. Veo 3.1 costs $0.40 a second with audio on both, Kling 3.0 Pro is half the price on fal at $0.112 a second and Seedance 2.5 at 720p is about half the price on Replicate at $0.23 a second, though Replicate stops at 720p.
Which fal.ai alternatives support webhooks?
Replicate, Runware and WaveSpeedAI document webhooks, as fal does. Melius and Together AI return results by polling, and the Runway API's SDK polls with a wait helper.
Can I still use Veo through the Gemini API?
Not with the Veo 3.1 preview model IDs, which Google shut down on October 22, 2026. Google points developers to Vertex AI, where Veo 3.1, Fast and Lite are generally available, or to Gemini Omni Flash.
Does Seedance 2.5 support 4K through an API?
No. ByteDance's specification tops out at 1080p for Seedance 2.5. Seedance 2.0 does reach 4K, on BytePlus ModelArk and the Runway API.
Can I use AI videos from these APIs commercially?
Usually, subject to each model maker's terms. Replicate and fal label models for commercial use, and WaveSpeedAI says rights depend on the model's license. Melius says: "You own the content you create on Melius and can use, publish, and distribute it commercially, subject to the underlying model providers' terms. Melius doesn't claim ownership of your work and doesn't use it to train AI models."
