Velaterm is definitely installed here. Let me check how much space each piece uses and whether it's actually running.

Short answer: it's installed, it's RUNNING, and it's not bloating your disk — but it does hold ~1.8 GB of RAM for what's currently an idle service.
What's there (set up Aug 7 23:18, deliberately — headless terminal + agent manager at vela.openalgo.theworkpc.com, port 8799):
1. Disk footprint — trivial
- /home/ubuntu/Applications/VelaTerm.AppImage = 118 MB
- /home/ubuntu/.velaterm/ = 8 KB
- Total ~118 MB out of 47 GB free. Not bloat.
2. RAM — this is the real cost
- systemd shows the service holding 1.8 GB (peak 2.4 GB) — it's an Electron app
- Actual process RSS is tiny (~20 MB + 57 MB); most of that 1.8 GB is the 303 MB /tmp appimage extraction (tmpfs = RAM) plus cache, which the kernel reclaims under pressure
- Box has 11 GB total, 5.2 GB available, swap 1.4/2 GB used — so it's not hurting, but 1.8 GB for an idle Electron app is the single biggest service on the machine
3. Current usage
- Service active (running ~20h, HTTP 200 on its port)
- Only 1 local connection to it right now — that's the nginx reverse proxy keepalive, not a live user session. Nothing is actively using it at the moment.
So: no unnecessary disk space, but if you're not actually using the web UI, you can reclaim the ~1.8 GB instantly with `velaterm off` (it stays installed, just stopped; note it's systemd-enabled so it'll restart on boot unless you also disable it — say the word and I'll do that, or remove the AppImage + unit entirely to free the 118 MB disk too).

USER (hermes, deepseek-v4-flash)
so if i cross my browser it doesnt get killed? if i / exit
Correct — closing the browser (or the tab) does nothing to it. The web UI is just a client; the service is fully decoupled:
1. Close browser tab / drop the WebSocket → only that connection dies. The VelaTerm process keeps running headless under systemd. Nothing detects or cares that you left.
2. /exit inside a web terminal → kills just that shell session (like closing a terminal window on a local machine). The velaterm service and its agent manager stay up.
3. Even killing the process itself doesn't finish it — the unit has Restart=on-failure with RestartSec=5, so systemd brings it back within 5 seconds. And it's enabled (WantedBy=multi-user.target), so it also comes back on every boot.
The only ways it actually stops:
- `velaterm off` → stops it now (but it comes back on next boot)
- `velaterm off` + `sudo systemctl disable velaterm` → stops it and keeps it dead until you `velaterm on` again
- remove the unit + AppImage → gone for good
So it's a 24/7 resident service regardless of what you do in the browser. Want me to disable it so it stops eating the 1.8 GB when you're not using it?

USER (hermes, deepseek-v4-flash)
so how can switch off and switch on -demand
2026-08-08 20:02
ASSISTANT (hermes, deepseek-v4-flash)
`velaterm off` / `velaterm on` already do exactly that — the wrapper script handles stop/start. There's just one catch: the service is enabled for boot, so plain `velaterm off` only lasts until the next reboot. For true on-demand:
1. Switch off (and keep it off across reboots — this is a one-time step):
`velaterm off && sudo systemctl disable velaterm`
Now it stays dead until you say otherwise.
2. Switch on whenever you need it:
`velaterm on`
(start works fine even while disabled — the disable only affects boot autostart, not manual start)
3. Check state anytime:
`velaterm status` → active / inactive
So the daily rhythm is just `velaterm on` when you want the terminal, `velaterm off` when you're done. The disable in step 1 is done once and forgotten.
Want me to tweak the wrapper so `off` also auto-disables and `on` is enough to bring it back? Then you'd never have to remember the systemctl part.

There's no chat gateway on this box (no Telegram bot running — only the CLI), so from your phone it comes down to two realistic routes:

{"question": "Which way do you want to switch velaterm from your phone?", "choices_offered": ["SSH app on phone (e.g. Termius) — zero setup, you already SSH to reach me", "Build a tap-link: a small HTTPS page on vela.openalgo.theworkpc.com where one tap toggles the service", "Auto schedule instead — e.g. off at 23:00, on at 09:00 every day"], "user_response": "SSH app on phone (e.g. Termius) — zero setup, you already SSH to reach me"}

ASSISTANT (hermes, deepseek-v4-flash)
You already have the answer in your pocket then — the SSH session you use to talk to me is the same box. Two ways:
1. In that same terminal (after exiting hermes, or in a second session), just type:
`velaterm on` / `velaterm off` / `velaterm status`
2. Or zero typing: you're already chatting with me over that SSH — just say "velaterm off" (or on) in this chat and I'll run it for you. That works from any device that can reach me.
One-time setup so it stays off across reboots (otherwise `off` only lasts till next boot):
`velaterm off && sudo systemctl disable velaterm`
Then `velaterm on` whenever you want it back — start works fine even when disabled.
If you use Termius, you can even add `velaterm status` as a snippet for a quick glance. Want me to run the disable step now so it's truly on-demand from here on?
