Rain Sounds for Sleeping: the website that goes dark

Rain Sounds for Sleeping is a single-purpose website that plays a continuous loop of natural rain and gentle distant thunder, then removes itself from view: press one button and the screen turns completely black while the sound keeps going. It is worth a look because it does exactly one calming thing and then refuses to do anything else.

In brief

• One button starts a looping recording of rain and distant thunder, and the screen goes fully black.
• It is free, with no accounts, no adverts, and no subscriptions.
• The audio is built from three public-domain field recordings, each credited by name and licence.
• The recording downloads once, then the open tab reuses it rather than streaming forever.

What the site actually does

The homepage of Rain Sounds for Sleeping is almost aggressively plain. There is a heading, a line of description, and a single button that reads Start rain. The description states the intent plainly: natural rain and gentle distant thunder for sleep, reading, or winding down. There is nothing to configure, no playlist, no timer wheel, and no mixing desk of separate rain, wind, and fire sliders.

Press the button and two things happen at once. A prepared recording begins to play, and the screen goes black. Not dimmed, not a dark theme, but black, with the controls gone from sight. The sound is the only thing left. To bring the page back you interact with it again, which is a deliberately low-friction way to stop or check on it.

That is the entire product. The restraint is the point. Most ambient-sound apps grow outward into accounts, streaks, premium tiers, and a dozen layered loops. This one stays a single page that makes a single sound and then gets out of the way.

The page itself reinforces the mood before the audio even starts. Below the button sits a short set of questions and answers about the rain, written in plain language: whether it loops, whether it is free, whether it keeps downloading. There is no onboarding tour and no cookie wall to dismiss first. The whole thing reads in under a minute, which is roughly how long most people are willing to spend setting up something they intend to fall asleep to.

The genre it belongs to

Rain on the internet is a small, well-populated genre. The best-known example is RainyMood, which has looped a thunderstorm in the browser since the late 2000s and taught a generation of students and remote workers that a tab could be a weather machine. Whole corners of streaming platforms are given over to rain-on-a-window loops that run for hours.

Rain Sounds for Sleeping sits in that lineage but trims it hard. Where many rain sites reach for video of water running down glass, lofi music, or elaborate scene mixers, this one drops the picture entirely and keeps only the audio. It is a bet that for sleeping, specifically, the image was never the point, and that a screen showing anything at all is a screen worth turning off.

The result is less a competitor to those sites than a stripped-down argument about what the category is for. If the goal is to look at pretty rain, keep the video. If the goal is to stop looking at anything, this is the more honest tool.

Why the screen goes completely black

The black screen is the most unusual decision here, and it solves a real bedroom problem. A phone or laptop left playing rain is usually also sitting there glowing. Even a dark interface still emits light, and a bright panel in a dark room is the opposite of winding down. By painting the whole viewport black, the site turns the device into something closer to a speaker than a screen.

There is a practical bonus on many phones and laptops. Displays built on OLED panels switch individual pixels off when they show true black, rather than shining a backlight through a dark filter. A fully black page therefore asks less of the panel than a dark-grey one. The site does not promise battery figures, and the honest answer is that it depends on the hardware, but the direction of the effect is real on OLED devices.

The quieter benefit is attention. A visible interface invites fiddling: checking a timer, nudging a volume slider, reading the next suggestion. Remove the interface and there is nothing to do but listen, or sleep. The black screen is less a gimmick than a way of ending the session with the user before the user has to end it themselves.

Where the rain actually comes from

Most sleep-sound sites never say where their audio originates. This one publishes a sound credits page that names every recording and its licence. The rainstorm is a mix of three separate field recordings, and the transparency is unusual enough to be worth reading on its own.

The base layer of rain is Summer Rain on Terrace by Joseph SARDIN, catalogued as sound 1019 on BigSoundBank, a royalty-free library the recordist has run since 2005. The recording captures large drops of a summer storm falling on a terrace, in stereo and outdoors, which is why it reads as real weather rather than static.

Over that sit two thunder recordings from Freesound, the long-running collaborative sound archive. The first, Peal of thunder, distant, is by the contributor bastipictures and was captured with a handheld recorder. The second, a dry rolling distant rumble recorded at dawn, is by the contributor TRP and can be found at its own Freesound page. Both are deliberately far-off, so the thunder suggests weather on the horizon rather than a storm overhead.

Public domain, by choice

Each of the three recordings is released under the CC0 1.0 Universal public-domain dedication, the tool Creative Commons provides for waiving copyright entirely. CC0 permits commercial use, editing, and redistribution with no attribution required, which is exactly why a small website can legally build a product on top of them. The credits are offered as thanks rather than obligation, which is a nice distinction the site bothers to make.

The recordings were not simply bolted together. According to the credits, they were filtered, levelled, mixed, and converted for the site, and a short crossfade joins each repeat so the loop does not click or jump. The source and licence records are kept in the project repository, which is the sort of housekeeping most ambient sites never mention because most never do it.

The honesty is worth dwelling on. A sleep-sound app is about as low-stakes as software gets, and nobody was going to audit where the rain came from. Crediting three strangers and linking their licences anyway is a small, unforced gesture of good manners. It also quietly makes the case for public archives: a usable product here exists only because recordists chose to give their work away under terms that let anyone build on it.

A recording, not a stream

There is a small technical idea hiding behind the calm. The site explains that the recording downloads when you press Start rain, and that once it has loaded, the open tab reuses it rather than fetching it again. In other words it is a file that loops locally, not an endless stream pulled from a server.

That choice has pleasant consequences. After the initial load the sound keeps going even if the network drops, which matters for a device left running overnight. It also means the site is not quietly consuming data for hours, a reasonable worry for anyone who has fallen asleep with a video streaming. The weather you hear is a few minutes of audio repeating, not an infinite broadcast.

It is a reminder that the web can still serve a static asset and then leave you alone. No session to keep alive, no telemetry to send, nothing to reconnect to. The tab becomes a self-contained little rain machine for as long as you leave it open.

What it deliberately leaves out

Half of what makes the site restful is a list of things it does not have. There is no sign-up, so there is no password to invent and no email to hand over. There is no sleep timer, which sounds like an omission until you realise a loop that costs nothing to leave running does not really need one. There is no library of alternative sounds, no forest, no cafe, no white-noise generator competing for the same slot.

There is also no account-shaped memory of you. The site does not track a streak, award a badge, or nudge you to come back tomorrow night. For a product aimed at the moment just before sleep, the absence of any growth mechanic feels less like a missing feature and more like basic courtesy.

The clearest omission is the visual one. Nothing animates, nothing pulses in time with the thunder, and once the screen is black there is not even a progress bar to watch. The site trusts that the sound is enough, and for its single purpose it usually is.

Rain as a sound you stop hearing

Steady rain works as background because it is broadband and featureless. It fills the room with a soft, even wash of sound across a wide range of frequencies, and a continuous wash tends to blunt the sudden noises that would otherwise snag attention: a car door, a creaking floor, a partner turning over. The point is not that rain is interesting, but that it is reliably uninteresting.

The distant thunder is doing something slightly different. A loop of pure rain can start to feel mechanical once the ear learns its length. Occasional low rumbles, kept far away in the mix, add just enough variation that the brain reads the loop as weather rather than as a repeating file. It is a small amount of unpredictability used to hide a predictable loop.

There is a reason the recordings were chosen to be distant rather than dramatic. A close thunderclap is a startle, which is the last thing a sleep aid wants. Keeping the thunder far off in the mix means it registers as atmosphere rather than event, something the ear can file as weather and ignore. The rain does the masking; the thunder keeps the loop from feeling like a loop.

None of this is a medical claim, and the site makes none. It does not promise deeper sleep or measured results. It offers a plausible, pleasant sound and lets the listener decide whether it helps, which is a more honest posture than the wellness industry usually manages.

How it fits the boring web

Rain Sounds for Sleeping is part of the Boring Websites family, a small collection of deliberately modest, single-purpose sites. The label is affectionate. These are pages that pick one unglamorous job and do it without the usual scaffolding of pop-ups, upsells, and attention traps.

Seen that way, the rain site is a close cousin of something like the Bureau of Very Slow News, which answers the frantic pace of the news cycle by slowing it almost to a stop. Both take a familiar genre, ambient sound or breaking news, and strip it back until only the calm, useful core remains. The black screen is simply this family's instinct taken to its logical end: the most boring interface is no interface at all.

There is also a quiet argument in here about what a website can be. Not a platform, not an app, not a funnel, just a page that makes a sound. It loads, it works, and it asks for nothing. In an era of permission prompts and cookie walls, that is close to radical.

Using it well

A few practical notes make the site behave. Because the audio is a loop at a fixed level, the volume lives entirely on the device: the page offers no slider, so set the system volume before the screen goes dark. The recordings sit at a gentle level by design, so a very quiet room may want a touch more than expected.

The one genuine caveat is screen lock. The site is candid that whether playback survives a locked phone depends on the device and browser, because some combinations pause audio when the screen turns off. On a phone the safest approach is to leave the tab in the foreground with auto-lock disabled for the night, or to run it from a device that is happy to keep a tab playing, such as a laptop or tablet left open on a bedside table.

For reading or working rather than sleeping, the black screen is less relevant and the loop simply becomes a background wash. In that mode it competes directly with sites like Rain Sounds for Sleeping's better-known relatives, and wins mainly on the quality of its source recordings and its refusal to clutter the page.

It also pairs well with the way people actually use browsers. Pinned as a tab, it costs almost nothing to keep around: start it when a quiet hour begins, bring the page back and interact with it when the hour ends. Because the sound is a local file rather than a stream, you can even start it, let it load, and then carry a laptop out of Wi-Fi range without the rain cutting out. For a tool this small, that resilience is a large part of why it earns a permanent spot.

FAQ

Does the rain actually loop, or is it endless?

It loops. The site is honest that a prepared recording repeats continuously, with a short crossfade joining each pass so the seam is hard to hear. It is a file playing on repeat, not a live or generated stream, which is why it keeps working even if your connection drops.

Is it really free, with no catch?

Yes. The site states there are no accounts, no adverts, and no subscriptions. It is a static page built on public-domain audio released under CC0 1.0, so there is no paywall to hit and nothing to sign up for.

Will it keep playing when my phone locks?

Sometimes. The site is upfront that this depends on the device and browser, since some phones pause audio when the screen locks. If it stops on lock, disable auto-lock for the session or play it from a laptop or tablet instead.

Where does the sound come from?

From three CC0 field recordings: Summer Rain on Terrace by Joseph SARDIN on BigSoundBank, plus two distant-thunder recordings by bastipictures and TRP on Freesound. They were filtered, levelled, and mixed into the single loop you hear.
