StateSync is an alternative to RTK

StateSync vs RTK

RTK filters what shell commands print. StateSync removes only output that adds nothing, and the agent finishes in fewer, shorter requests.

Where StateSync wins

Nothing useful is filtered away.

RTK drops passing tests and cuts long lines, so the agent can end up running a command again. StateSync removes only what adds nothing: colour codes, progress bars, repeated lines.

Savings everywhere, not in one place.

RTK saves only on shell output, and on TokenBench it cost 1.2% more than plain Claude Code. StateSync saves on shell output and on finding code, and the agent finishes in fewer, shorter requests.

The agent finds the right files sooner.

StateSync maps your project on your computer, so the agent spends fewer turns looking.

Hit a limit, keep going.

Move the conversation to another agent or account mid-task, with the same history. RTK has nothing like it.

Pick RTK if you want a free tool, or use an agent StateSync does not run, such as Gemini CLI, Windsurf or Cline.

Questions

What is an alternative to RTK?

StateSync is an alternative to RTK. RTK filters what shell commands print. StateSync removes only output that adds nothing, and the agent finishes in fewer, shorter requests.

Does StateSync compress shell output too?

Yes. It removes colour codes, progress bars and repeated lines, and keeps every line the agent can use.

Can I use StateSync and RTK together?

No. StateSync compresses tool output through its own tool, and two compressors on the same output do not work together. If you use StateSync, turn RTK off.

Is RTK free?

Yes, under Apache 2.0, with parts under BUSL 1.1. StateSync is from $8 a month, with 7 days free.

RTK's figures are its own and its testers', as published. StateSync's come from our own run on one model, so the two were not measured the same way.
