Coasty - A Computer-Use-Agent that runs legacy software like a human
by•
Coasty is a computer use agent that operates real desktop software end to end. Started with healthcare prior auth, automating payer portals and legacy EHRs, and data removal for data privacy but now we're expanding into insurance and tax & accounting. Coasty does that work autonomously, with human takeover and full audit trails. Independently verified at 82.81% on OSWorld Verified (359 tasks), near the top of the leaderboard. No APIs required. If software has a screen, Coasty can run it.

Prateek, congrats on Coasty. 82.81% on OSWorld Verified while actually driving legacy payer portals and old EHRs, not clean demo software, is a serious number
how fast does the VM actually spin up when I need to fire off a quick agent task, is there cold start latency to worry about
Coasty
@kaanalayandvxb The VM spins up slow(about 2m) since it's an instance that lasts forever but we are working on making it even faster.
Running legacy software like a human sounds like a practical use case for computer-use agents. I’m curious how much setup is typically needed before an agent can reliably interact with an existing application.
Coasty
@amjad_shaik Not much setup is required! Just download the local version of Coasty and run it.
@nitish_kovuru That’s simpler than I expected. Does Coasty rely mainly on observing the UI like a human user, or does it also learn workflows over time to become more reliable with repeated tasks?
Coasty
@nitish_kovuru @amjad_shaik The former but we're also training our models on the data to make it even better!

@steven_snider We were horizontal haha. We’re still exploring which vertical to focus on but prior auth and healthcare was one of the first.
Curious how the cold start time compares to something like a warm lambda since spinning up a fresh VM per agent sounds like it could add real latency for quick browser automation tasks.

@vedat2091990Â Hey we currently do cold starts, so wait times are longer, but watch out for updates :) we will make it superfast in upcoming times
a dedicated VM per agent instead of a shared container pool is a real security win but I'd expect that to cost noticeably more per-agent, not less. how are you undercutting AWS/GCP on price while giving up the efficiency of shared compute - is it just thinner margins, or some trick on the VM provisioning side
Coasty
@omri_ben_shoham1Â definitely made tradeoffs in some areas.

Another feature, that enterprises love, is the Audit Trail! Keep Coasty accountable with a full replay of the session and every step taken in detail. Here's an example one for data removal in data privacy: https://coasty.ai/share/b28c6b0a-faad-4647-824c-67c4a3d2654f

In the enterprise platform and the developer api, you get a much deeper view of every log with timestamps.
