I need a websafe alternative to DIN font. It needs to be free for commercial use. Anyone know of a good one?
The situation has changed since this question was first asked in 2012.
There is now an OFL-licensed, completely free/libre version of DIN called Alte DIN.
This is legal because DIN 1451 is a product of the German government, and so is in the public domain -- only the individual interpretations of it by various font foundries are protected and copyrighted. Thankfully Peter Weigel traced it for us!
A corporation called 'Datto' commissioned Monotype creative type director Charles Nix to create a DIN-like font which was released in 2018 under the SIL OFL 1.1.
As of 2021, it is no longer available on their website, but you can find it on a reputable site like FontSquirrel or GitHub. "Altinn" (Github) is a fork of this project on Github. "Dinish" (Website)(Github) is a fork of this project with continued development, which has also been submitted to Google Fonts.
Original answer (2012):
I don't know how close you need to come to the DIN typeface, but I found a couple possibles on Google Web Fonts. Using the letters
aGgQqlJ to narrow down the letter shape matches, I found:
Wire One - https://fonts.google.com/specimen/Wire+One
The lowercase letter shapes are quite similar. The overall font is a bit more more condensed than DIN and some of the capital letter shapes are different.
Also, not an exact match but the feel is quite similar.
There's an open source DIN-inspired font called Gidole:
Cabin is a pretty good free alternative to DIN. Well, it may be fairly different in design but bear with me - sometimes it can feel as if it is similar:
Try Gesta from Typekit. I's very similar. https://typekit.com/fonts/gesta
Here's a bolder version inspired by DIN:
ROPA SANS - https://fonts.google.com/specimen/Ropa+Sans
If you have access to Windows fonts, the recently announced Bahnschrift looks to be Microsoft's interpretation of the DIN outlines. In some time it will be available on many computers running Windows and could well be a good, free and close representation of what paid DIN fonts offer.
Our new first OpenType Variable Font Bahnschrift is now included in builds. This new font industry standard enables us to pack an entire typeface family into a single file with infinite variability. No longer are you constrained to simple weights like Light, Regular, and Bold. Now you can have an infinite range of font styles, with smooth interpolation from Light to Bold and beyond. Better still: because a single, efficient variable font can replace several static fonts, variable fonts save a lot of space.
I like Gesta as a stand-in for DIN. It's not actually all that similar (Gesta is more stylized) but the x-height and overall mood seem to match very well.

John's suggestion of Abel seems good, too. I haven't compared the fonts very closely, but it's got a DIN feel to it at non-display text sizes with a character width sitting somewhere between Engschrift and Mittelschrift.

TRY roboto .It looks almost like DIN and it comes in so many styles . Its feels really premium. http://www.fontsquirrel.com/fonts/roboto
"Oswald" font is a pretty good alternative. It's a google web font, so it's the best possibility for websites ;-)
I have used Babel Sans as an alternative to DIN: http://www.dafont.com/babel-sans.font
Although it is bit thin.
Titillium Web is also a free alternative:
DIN Next from Linotype would be the commercial version with webfonts available:
