Makernice Team · 2026-11-11 · Updated 2026-11-12 ## Key takeaways - MuAPI, Crun, Makernice and reAPI each carry all of the Seedance 2.5, Seedance 2.0, Happy Horse 1.1 and Kling 3.0 models I2V sells, plus Wan and MiniMax models that I2V's catalog does not match in ours. - I2V sells one-time credit packs that work in both its Studio and its API, shows the credit cost before you submit, and returns credits automatically when a generation fails. - MuAPI and Makernice both pair an API with a browser workspace; Crun and reAPI are API platforms billed in credits per request or per completed generation. - Stay on I2V if you want a studio-first product with API access added, a 7-day refund window after purchase, or bank-transfer billing for volume.

If I2V's catalog or its credit packs no longer fit, the alternatives to look at are MuAPI, Crun, Makernice and reAPI. Each one sells every Seedance, Kling and Happy Horse model that I2V does, and adds Wan and MiniMax versions on top. Two of them, MuAPI and Makernice, also let you run jobs from a browser, which matters if you use I2V's Studio today. All pages here were checked on November 11, 2026. ## What does I2V combine, and what does it leave out? I2V, sold at i2v.ai, combines a studio and an API on one pool of one-time credits, and what it leaves out is mainly catalog breadth. I2V calls itself an "AI Image & Video Studio + API". Credits are bought in one-time packs, from 780 credits on the smallest to 84,000 on the largest, and "One-time credits you purchase remain available in your account for Studio or API use." Before a job runs you "See the model, resolution, and credit cost before submitting.", and "Failed generations return credits automatically." Eligible new accounts receive a one-time welcome credit, and volume buyers can ask for bank-transfer billing. The limits are catalog and packaging. Of the models we track, I2V matches the [Seedance 2.5](https://makernice.com/models/seedance-2-5/), Seedance 2.0 and 2.0 Fast, [Happy Horse 1.1](https://makernice.com/models/happy-horse-1-1/) and [Kling 3.0 Standard](https://makernice.com/models/kling-3-0-standard/) and Pro lines, with no Wan, MiniMax or image models among them. Prices are shown per 5-second clip, with separate audio and video-input variants, and refund requests must be made within 7 days of purchase. We did not find a stated output retention period or a cancellation rule. ## Comparing four I2V alternatives MuAPI, Crun, Makernice and reAPI each sell every Seedance, Kling and Happy Horse model on I2V and add Wan and MiniMax versions. MuAPI and Makernice also run jobs from a browser, while Crun and reAPI are API platforms on the pages we checked. | Platform | Best for | How it bills | Source checked | | --- | --- | --- | --- | | MuAPI | Users who want a web studio, workflows and an API on one credit balance | Credits bought in advance and deducted per generation; credits never expire | [muapi.ai](https://muapi.ai/minimax-h3-image) · 2026-11-11 | | Crun | Developers who only need an asynchronous API and a free trial | Credits in top-up plans with a higher per-dollar rate on bigger plans; estimates settle on usage | [crun.ai](https://crun.ai/pricing) · 2026-11-11 | | Makernice | People who switch between a browser form and an API at the same price | Prepaid US-dollar balance per output second or per image; no expiry | [Makernice pricing](https://makernice.com/pricing/) · live price list | | reAPI | API buyers who need high concurrency and full refunds on failures | Credits at a fixed US-dollar rate, charged per completed generation | [reapi.ai](https://reapi.ai/models/seedream-5-5) · 2026-11-11 | The [I2V alternative page](https://makernice.com/alternatives/i2v/) turns I2V's 5-second clip prices into per-second rates and sets them next to the others for each shared model. Here the focus is how you buy and run. ## From credit packs to other billing styles **MuAPI** is the closest in spirit: an API platform that also runs Studio, Workflow, Agents and Apps features on the web. Credits are bought in an amount you choose through Stripe and deducted per generation, and they never expire. Its estimate endpoint gives the exact price of a specific request, and tasks can be submitted with a webhook. New accounts get a small free allocation; credit purchases are non-refundable once used, and we found no failed-task rule. **Crun** is API-only on the pages we read, with every generation run as an asynchronous task. It sells credits in four top-up plans, and larger plans give more credits per dollar, so the effective rate depends on the plan. Listed costs are estimates and the final charge follows actual usage. Generated media is kept 14 days, new requests are capped at 20 per 10 seconds, there is a free trial, and consumed credits are non-refundable. **Makernice** has a Create area in its console where the same 19 video and image models run from a form at the same price as the API, which covers the Studio habit without a separate credit pool. It has no editor, canvas or timeline. The balance is prepaid in US dollars with no packs, no subscription and no expiry; there are no free credits. Each run is priced before it starts, by a 12-minute REST quote or by the `max_cost_usd` cap on an MCP `generate` call, and failed or timed-out runs are not charged, though an output blocked by moderation is. Coding agents connect through the [Claude Code](https://makernice.com/mcp/connect/claude-code/) and [Cursor](https://makernice.com/mcp/connect/cursor/) guides. **reAPI** prices credits at a fixed US-dollar value and charges per completed generation, per token, image or video second depending on the model. Failed generations are refunded in full. Default limits allow 100 concurrent media tasks, credits last while the account is active, and new accounts start with free credits. Payment options include cards, Apple Pay, Google Pay, PayPal, WeChat Pay, Alipay and BTC, USDT or USDC, and results are polled by task id. ## Browser use and API use on each platform MuAPI and Makernice are the two I2V alternatives here that keep a browser side next to the API, each on the same balance as its API calls. Crun and reAPI document an API only on the pages we checked. - **I2V:** Studio and API share the same one-time credits. - **MuAPI:** Studio, Workflow, Agents and Apps on the web, plus the API, on one credit balance. - **Makernice:** a console Create form and the REST API or MCP server, same models and same price; results by polling, a per-job `callback_url` or an account [webhook](https://makernice.com/docs/#webhooks). - **Crun and reAPI:** we found API documentation only on the pages we checked. ## When is I2V still the simpler pick? I2V suits creators who start in a studio on i2v.ai and only sometimes call the API, because one pack covers both. Its 7-day refund window after purchase is more generous than the non-refundable terms MuAPI and Crun state for used credits, and the welcome credit lets you try before buying. Teams with volume needs can also arrange bank-transfer billing. If those fit, staying is reasonable; the [I2V alternative page](https://makernice.com/alternatives/i2v/) compares the shared models one by one. ## Frequently asked questions #### Does I2V return credits when a generation fails?
