Rendobar vs Rendi

Rendi and Rendobar both run standard FFmpeg in the cloud. Pick Rendobar for a free tier with $5 of credits and no credit card, native MCP tools an agent can call, a predictable per-minute bill, and cheaper downscales. Pick Rendi for the lowest per-gigabyte price on standard transcodes, up to 32 vCPUs on a single command, or a large free processing quota. Both run the exact command you already write.

Both take the FFmpeg command you'd run locally and run it in the cloud. The call comes down to what you optimize for: raw per-gigabyte price, or predictable billing plus a no-card free tier and native MCP.

Verdict

The short answer

Pick the side that matches how you work.

Pick Rendobar if

  • You want to start without a credit card. Rendobar gives $5 of signup credits, no card. Rendi asks for one.
  • You're building an AI agent that should submit and track jobs itself, not just read documentation.
  • You want a full toolchain. Rendobar ships a typed SDK and a CLI, plus webhooks for Zapier, Make, and n8n.
  • You want a bill you can predict. Per-minute pricing stays flat whether the file is 50 MB or 5 GB.
  • You downscale large masters, where per-minute pricing beats paying for every gigabyte going in.
  • You'll want more than FFmpeg later. Animated captions and burned-in subtitles are live on the same API.

Pick Rendi if

  • You run standard same-resolution transcodes and want the lowest raw price. Per-gigabyte billing is usually cheaper there.
  • You need a single command to use up to 32 vCPUs of horsepower.
  • You want a large free processing quota and don't mind verifying a card.

Scenarios

4 real builds. Who we'd pick.

For each one, the API we'd actually reach for, and the reason. No hedging.

Pick Rendobar

You already have a working FFmpeg command and just want it off your box

Both solve this. You POST the command, a sandboxed container runs it, you get an output URL. The tiebreaker is the first five minutes. Rendobar runs your first job on $5 of credits with no card. Rendi asks you to verify one first.

Pick Rendobar

You're building an AI agent that cuts, transcodes, and captions on demand

Both ship an MCP server, but they differ. Rendi's serves documentation so an assistant can write your integration. Rendobar's MCP tools let the agent run the job itself, poll it, and fetch the result. For an agent that acts, that's Rendobar.

Pick Rendi

You run high volumes of standard 1080p transcodes

Here Rendi usually wins on price. 1080p H.264 files are small and compress well, and Rendi bills per gigabyte, so a standard same-resolution transcode is the cheaper line on Rendi. If raw cost per job is what you optimize for and your inputs aren't huge, that is a real edge.

Pick Rendobar

You downscale large 4K masters to web-ready 1080p

Now it flips. Rendi bills every gigabyte, so a heavy 4K master means paying for all those gigabytes going in. Rendobar bills per minute of compute, so shrinking that master to 1080p is priced on the work, not the file. For downscales, Rendobar lands cheaper.

Pricing

Pricing math: Downscaling a 4K master to 1080p

One minute of a 4K source re-encoded to 1080p. Rendobar bills the compute. Rendi bills every gigabyte, and a 4K master is a lot of gigabytes going in. This is a case the per-minute model wins. See the note below for where it does not.

Rendobar (ffmpeg)

~$0.04

About 1 min of 1080p compute at ~$0.04/min. $0 base on Free, no card. Pro is $9/mo with $5 of included credits.

Rendi

~$0.06

~0.4 GB processed at Rendi's published ~$0.15/GB. The 4K input dominates the bill.

Per-minute billing is priced on the work, not the file. When the input is large and the output small, like a downscale, Rendobar comes out cheaper, and you know the number before you upload.

The honest other side: for a standard same-resolution transcode, 1080p H.264 files are small, so Rendi's per-gigabyte price is usually the cheaper line. Rendobar's edges there are predictability and the no-card free tier, not raw cost. Run your real files through both before deciding.

How we got these numbers
  • 1 minute of 4K H.264 input, roughly 0.35 GB, re-encoded to a 1080p output of roughly 0.03 GB.
  • Rendobar billed at ~$0.04 per output-minute at the default preset, from real measured jobs.
  • Rendi billed at ~$0.15 per GB processed, from its published pricing.
  • Base fees excluded. Rendobar Free has no base fee.

FAQ

Questions we actually get asked

Is Rendi or Rendobar cheaper?

For standard same-resolution transcodes, usually Rendi. 1080p H.264 files are small, and Rendi's per-gigabyte price comes out lower on those. Rendobar wins on downscales of large masters (you pay for compute, not the big input going in), on predictability (a flat per-minute rate that does not move with file size), and on the no-card free tier. Run your real files through both before deciding.

Do both run FFmpeg commands?

Yes. Both run the exact FFmpeg command you'd type in a terminal, in a sandboxed cloud container, with no template language in between. If you already write FFmpeg, either one removes the server you'd otherwise maintain.

Both say they have MCP. What's the difference?

Rendi's MCP is a documentation server that feeds an assistant your schemas and examples. Rendobar's MCP tools let an agent submit a job, poll it, and fetch the result itself. One helps write the code, the other runs the work.

Can I try each without a credit card?

Only Rendobar. It gives $5 of signup credits with no card that never expire, so the first videos you produce are clean and shippable. Rendi asks you to verify a card before you process anything, though its free quota is larger once you do.

Which is faster for big files?

Rendi. A single command can use up to 32 vCPUs, built for heavy jobs that should finish fast. Rendobar runs every job on an 8 vCPU machine, which matters less when you run lots of smaller jobs but is a real ceiling on single-command speed.

What can Rendobar do that Rendi can't?

Two things: native MCP tools an agent can call to run jobs, and higher-level jobs on the same API like animated captions and burned-in subtitles. Rendi stays focused on FFmpeg.

What does Rendi do better than Rendobar?

Raw price on standard transcodes, single-command horsepower (up to 32 vCPUs), and free-tier volume (50 GB a month once you add a card). For a high-volume pipeline of ordinary 1080p transcodes, Rendi is a strong and often cheaper option, and we'd tell you to use it.

Why pick Rendobar over Rendi?

Start with no credit card, run jobs from an AI agent over MCP, get a flat per-minute bill you can quote before you upload, pay less on downscales of large masters, and add captions and subtitles on the same key. If your priority is the lowest raw price on standard transcodes, Rendi may be the better fit.
