Anime: Boku dake ga Inai Machi
Boku dake ga Inai Machi like Steins Gate is about the main guy who has the ability to time-travel to the past to save someone dear to him. He ends up also having to save another girl from a tragic fate which he has romantic feelings for. Both anime start with a light mood and change drastically to a darker tone, dealing with the constant struggle of the hero endlessly trying to change the outcome of the future by changing the past. Also, If you watch Steins Gate the movie, you will find extra similarities with BDGIM.

Anime: Re:Zero kara Hajimeru Isekai Seikatsu
How would I put this?
Steins;Gate meets fantasy world?
Like Steins;Gate, I had a hard time really getting into the series because the first few minutes are pretty slow, but unlike Steins;Gate, this show gets down to business really fast. Both shows have an interesting cast of characters that all have their unique quirks.
If you liked this show but haven't watched Steins;Gate, from the impression I have after 3(4?) episodes, you'll probably like S;G!

Anime: NHK ni Youkoso!
The idea that a secret organisation, according to the protagonist, is conspiring against him is a similarity. At the same time both series are perverted and both have a somewhat weird/special female side-character.

The main characters in both series also seems a bit awkward when trying to interact with 'normal' people, yet somewhat like a leader among their own small clique/group of friends (which seems to be a coding guy and the weird girl in both series).

Besides that, they also have in common that reality seems somewhat off or twisted to the protagonist. There might be more, but this is  read more

Noein is a lot more ambitious than Steins;Gate, which preferred to stay within time travel limited to days-weeks and the same area. In Noein, the other selves of the child cast time travel with enhanced bodies; conversing with their younger selves as they fight using superpowers and struggle to sustain their bodies in a dimension they don't belong in.

Anime: Higurashi no Naku Koro ni
Both are thriller anime with a great deal of suspense and mystery. They both start out with a light almost happy go lucky feeling then everything turns dreadfully..dreadfully wrong. They both have great plot's, and while at first they may actually confuse the other. Higurashi just has a considerably greater amount of gore than steins;gate, but both are excellent watches. IF you like one you will probably like the other too.

Anime: Death Note
Both animes are about the main characters trying to change the world through unnatural means (Death Note / time travel). The protagonists Light and Okabe are both geniuses, but while Light is a self-confident evil mastermind, Okabe is a good-hearted 'self-proclaimedly mad' scientist with a fair bunch of ridiculous inventions. Both have clever plotlines that will always keep you on attention and at the edge of your seat, wanting to learn more.

Anime: Suzumiya Haruhi no Shoushitsu
This movie deals intricately with witty character interaction, good character development, and extremely similar elements of time-travel. The animation and art are both great, and the music will really pull you into the show. There are tense moments that will keep you on the edge of your seat, and there will be light-hearted moments where you can laugh. Either way, if you watch either, be prepared for one heck of a ride!

Important note:The Disappearance of Haruhi Suzumiya is only a movie you can only fully appreciate if you have watched the previous two seasons adapted before it.

Anime: Durarara!!
Durarara!! and Steins;Gate share quite a few interesting themes:

* Both start off with a slow paced "slice of life" ambience that, very subtly, foreshadows the following...
* ...Jump into a neatly intertwined plot.
* Insane characters;
* Norse Mythology references;
* A sprinkle of metaphysics: Time Travel (in Steins;Gate) and Norse Myth Fairies (in Durarara!!).

If you liked any of these aspects in one series, you'll most likely also enjoy the other.

Both are very exciting anime, with lots of plot-twists, well-made and rich stories, great voice acting and lots of thrills.

In Steins;Gate you get to see time-travel and all its effects on the human mind and its possibilities.

While in Code Geass you see the ambition of a young man who gets the power to command anyone to do anything and manages to create an uprising against an empire (Britannia).

Anime: Seikimatsu Occult Gakuin
This recomendation is made specifically for those looking for any and every Anime dealing with time travel. I prefer Seikimatsu, but each series has its own charm and own take on the whole matter. One is also more supernatural then the other, where as the one that is less simply deals with time travel. The characters I think are the best part of poth, as they have characters who are quite gripping.

The settings are definitly different and at a first glance it may not seem that they are similar. They are both humouristic and have a nice feeling to them, but in both shows there are some events that puts the main characters on the edge and the story becomes a bit more complicated and darker. There are supernatural elements but both shows focus on the relationships between the characters and how they develop and deepens through out.

Anime: Baccano!
While Baccano is not about time travel, I feel that people who enjoy Steins;gate should try out Baccano. It is bloodier than Steins;gate, but full of mystery and you get the thrill of understanding more and more each episode. Once you finish the series, you will want to rewatch it to understand it better just like Steins;gate.

Anime: Charlotte
The core elements are what obviously link the two animes. Lovely optimistic characters, good story line with dramatic depth twist and humor. Steins gate got it all. Charlotte is good but not as detailed as steins gate is with double the amount of episodes. So if you enjoyed Charlotte you might get a really lucky find with steins gate.
But otherway round also works ;P

Steins;Gate goes into more detail of this problem with a slower pace and how the main character overcomes it.

The two Animes starts with a humorous beginning where there are two male protagonists. The two protagonists are intellectual of their surroundings and will make the impossible into a possible situation.

Powerful organizations target the main characters. Conspiracies/terrible secrets are uncovered.

While Steins;Gate deals with time-travel theories, avoiding world domination, and preventing death (and a serious love story), Canaan explores a past involving human experimentation, rivalry, and loss. Both involve a character shouldering a burden while doing whatever they can to save a dear friend.

Canaan has a lot more intense fighting, but lacks a traditional love/relationship development.

Zipang, they have a vast amount of knowledge to draw from that will help change a large war and subsequent events to come but try not to leave any significant impact on the timeline for fear of the butterfly effect and grandfather paradox.

Two quality sci-fi anime. Whereas Steins;Gate tackles the concept of time-travel, GitS 2: Innocence questions the ethics of making cyborgs/robots, and reveals the vulnerability of AI to hacking and viruses. While SG's plot is slightly stronger, GitS 2: Innocence makes for a more compact viewing, and the graphics are stunning for a 2004 anime. Since GitS 2 is reminiscent of a good old cop story, be prepared for some gunfights and explosions!
