termalFiles · SFTP
The SFTP client that edits files where they live.
Browse remote files next to a full terminal and open them right there — a real editor with syntax highlighting, search & replace and in-place save. Add a dual-pane file manager with drag & drop, plus FTP and S3 in the same window, and you're running one app instead of a terminal plus a separate FTP client.
Free tier · 14-day Pro trial · Windows, macOS & Linux
01 / the built-in editor
Edit remote files in place — no download-edit-upload loop.
Most SFTP clients make you download a file, edit it in another app, and upload it back — and hope you grabbed the right copy. Termalin opens the file where it is: a real editor with syntax highlighting, search & replace, word wrap and in-place save, right next to the terminal.
- ▸More than code — open images, PDFs, Markdown, CSV and archives in place, not just configs.
- ▸Everything you expect from SFTP — browse remote directories, upload and download, and save back in place, with no round-trip through a local copy.
- ▸The terminal is right there — edit the config, then restart the service in the same window.
02 / dual-pane transfers
Two panes, drag & drop — even server to server.
The dual-pane file manager puts two locations side by side and lets you drag between them — local↔host or host↔host: one drag moves a file from server to server. No more downloading from one box just to re-upload it to another.
03 / beyond sftp
FTP, S3 and more — the same window for all of it.
One file workflow across protocols: FTP, Telnet and Serial/COM are first-class hosts with the same tabs, files and history, and S3 and S3-compatible buckets browse like any other host — list, upload, download, rename and delete, with keys used only for the request. There's a browser cabinet too: sign in at termal.in/account for SFTP, FTP and S3 file browsers from any device, phone included, with no install.
04 / one app, free
A full SSH client around it — free, with no host limits.
The SFTP browser isn't a bolt-on to a viewer — it lives inside a complete SSH client: browser-style tabs, a hosts sidebar, a live status bar with CPU, memory, disk and network, and session recording & replay. All of it is in the Free tier — the whole desktop app, local-only, no host limits, forever. Pro adds the encrypted cloud at $8/mo billed yearly, and every new account starts with a 14-day Pro trial.

Questions
Can I edit remote files directly over SFTP?
Yes — open a file in the browser and it opens in a real built-in editor: syntax highlighting, search & replace, word wrap and in-place save. No downloading a copy, editing it locally and uploading it back.
Is there a free SFTP client for Windows?
Yes — Termalin's Free tier is the whole desktop app with no host limits, free forever, on Windows 10 or later — and on macOS and Linux too. Paid plans only add the encrypted cloud, and every new account starts with a 14-day Pro trial, no card required. More on the free tier →
Does Termalin support FTP and S3 as well as SFTP?
Yes — FTP, Telnet and Serial/COM are first-class hosts with the same tabs, files and history, and you can browse S3 and S3-compatible buckets like any other host: list, upload, download, rename and delete, with keys used only for the request.
Can I move files straight between two servers?
Yes — the dual-pane file manager drags between panes, local to host or host to host: one drag moves a file from server to server, with no manual download-then-re-upload round-trip.
Do I still need a separate terminal app?
No — the file browser sits next to a full tabbed terminal with a live status bar, so you edit a config and restart the service in the same window. One app instead of a terminal plus a separate FTP client. See all features →
