IndieHackers.com will break $3-4k in monthly revenue this month or next,
mostly from advertising. It costs me <$200/mo to run. It features all sorts of
interviews with developers running profitable side projects themselves, so

I just signed up for versioning newsletter, all I did was pit in my email and
I got a quick confirmation.

I also signed up for oppsdaily, but the verification with MailChimp was quite
difficult. I had to select pictures with grass, then select images with house
numbers, then select new images with house numbers. You might want to consider
using a different provider.

~~~
kek918
This is Googles captcha system and its used by a bunch of services. It has
nothing to do with Mailchimp (except that they use reCAPTCHA) so changing
mailing list provider for this might not be a wise idea.

With that said, I much rather prefer this new reCAPTCHA compared to their old
version with hardly any readable characters.

Easy A - [https://easy-a.net/](https://easy-a.net/)

The website provides a semester simulator that can (accurately) predict
student grades, workload, etc for a given course / semester.

It also provides a breakdown of the grade distributions, work load (in hours),
difficulty, etc. For every course, professor, and combination there, for
universities on the site.

Profitable is relative, I spent around 100 hours tossing the website together
and make maybe $100+ a month with a freemium model. I have roughly 2500 active
users (not all paying), with zero put into advertising. There is probably
potential to grow this, but thus far prying money from students is painful.

I just posted a thread asking about design considerations for something like
this. There are a lot of monitoring sites but they are typically for
_internal_ consumption.

I am really interested in real-time, or timely monitoring of external
services. I'll check the service out, but curious if any of it is open source,
and hos you verify a site is up/down?

~~~
colinbartlett
It's not open source, but that's something I've considered.

And StatusGator doesn't verify that a service is up or down, it just reports
what a service reports. Most status pages have several components which are
either up, down, or warn, and StatusGator aggregates that same data from all
the various sources. If any component is down, that service is listed as down,
etc.

I was afraid of posting this because it will seem like an advert. But its not.
However, I do apologize if it violates an unwritten HN rule.

I help developers market themselves effectively. Its not a huge product, but
has a fair amount of demand. Feels good to help people move forward in their
carreers. Even helped one land a job that got him a visa. Not crazy
profitable, though. I charge less than $500 for something that can easily go
for ten times more. But money is not everything and it brings me joy to see
people move up in life. Currently only work with 2 people per month due tk
time constraints. So it does less than $1k a month. Pays for hobbies.

Its a side project that was born out of people on twitter wanting to hire my
shop (Yelluw) do it for them. But didnt make sense for them to hire a whole
shop to do something so small.

~~~
selectnull
Can you provide more information? How exactly do you help developers?

~~~
pryelluw
Well, turns out the average dev doesnt really know much about marketing. Some
are even against learning it. I simply work with them to establish an online
presence, a core brand (based on their skills and goals), a content strategy
(what to write about in order to get the markets attention), visual branding
(logo and website design), and time based plans to help them take action. Its
like a sort of marketing makeover. But without any BS because I hate mind
games.

~~~
andai
That last part got my attention! I'm currently studying internet marketing and
there's so much stuff out there that makes me uneasy... have you found any
resources for ethical marketing?

~~~
perlgeek
Marketing yourself as a developer can just be blogging, creating
videos/sreencaptures of you explaining some thing etc. You don't have to sell
anything, just convince people that you're worth employing.

Just the other day my boss discussed some hiring decisions with me, and he
said "the guy is too expensive. If he had a blog or an active github profile,
I could justify 10% more" (above what we'd usually pay for the position).

So, having a public blog with some contents and visitors can increase your pay
as a developer by 10% easily. If you're not comfortable with traditional
marketing, that's all you need to do.

And if you're lucky, you can also sell some courses on
pluralsight/udemy/whatever at some point, and make some extra cash on the
side.

~~~
pryelluw
Yes, with those simple things you can manage to develop a nice online persona.
Where I help people is more in how they are going to implement those ideas.
Blogging is not as simple as it sounds and some people need some help to get
started. They also need to write with an end goal in sight. I tell people to
blog as if you were to publish a book from your posts after 6 months. People
also tend to need help in structuring content. I help them learn how to write
technical content that does not end up reading like furniture instructions.

Depends what you mean by profitable.

[http://sites.creou.com](http://sites.creou.com)

It took about 4-6 weeks to build (fairly significant hours during that time).
It currently only has 1 paying customer, but they pay about 10% more than it
costs to host, so it technicaly makes profit month to month, but is unlikely
to ever make back the costs I sunk into it.

(Main problem is that although it was intended to be able to be used to build
lots of sites, I think in the end it was too closely tied to what the first
customer wanted, so although they love it, I've never been able to sell it to
anyone else, I've more or less given up on it now)

~~~
pryelluw
I sell something similar but charge at least a hundred times more per project
/ site. You should really promote this as the "local" (country based) solution
and raise prices. For £75 you will only get annoying cheapskates.

~~~
SimonPStevens
That's interesting because in the end I gave up because I felt like the space
was too over crowded with lower cost alternatives already. I had managed to
get a few potential clients but ultimately they all decided to go with other
companies that would offer them a fully custom site for a fixed price of
anything between £1000 and £4000. We had limits on how much we would customize
the sites because of how the engine was built, all the sites it produces
essentially follow the same template. And £75 per month passes £1000 after
only a year.

It seemed that we couldn't compete on price, because cheaper design shops
could throw together a template and charge £100-£200 total + only bare minimum
£5 budget hosting per month.

And we also couldn't compete on customisation or service because for only a
few thousand you can get a reasonable quality fully custom site.

I'd be interested to chat more if you were willing. (email in my profile).

People with side projects, how are you managing liability?

Browsing the projects on indiehacker, most of them are off-to-the-side (they
consume data and work with it and mostly that data is low valye) or
development related (things that are embedded or make pages but don't run in
production).

But a handful of them actually must have credentials for other service to work
or run in a trusted contest - in other words, they are used in ways that
expose the customer to security issues on the part of the operator of the side
project. What happens if you get pwned and cost your much larger customers
serious money?

My books on LeanPub:
[https://leanpub.com/u/raganwald](https://leanpub.com/u/raganwald)

I had been approached many times by tech publishers to write books from
scratch, but I never found the process and economics attractive.

Then I spotted LeanPub--quite possibly on HN--and I thought, "Hmmm, there is
nearly zero barrier to entry." They accepted Markdown, and I already had my
entire blog in Markdown on GitHub.

So I published a collection of essays
([https://leanpub.com/shippingsoftware](https://leanpub.com/shippingsoftware)),
and launched it with a "Show HN" style post, making the book free. LeanPub
allows people to pay more if they want, and an amazing number of people paid
more, I made $2,000 in one day just from being on the front page of HN.

I've written a few other books since then, but I firmly believe that writing
is a side project, not my profession, so I make a lot less than other authors
who really put their backs into it.

But I'm happy, and my readers are happy, and I get a little money every month
from people I like.

\---

A few observations that may be valuable for other side-projects, whether media
or software:

Some of my biggest wins were the books I _didn 't_ write. LeanPub has a
feature where you can cobble together a book title and a cover image, and it
creates a landing page that collects emails from interested readers.

Several times, I have created landing pages for books I was interested in
writing and when I promoted the landing pages... Crickets. I didn't write
those books.

Another thing that worked for me is that when I decided to write the original
JavaScript Allongé
([https://leanpub.com/javascriptallongesix](https://leanpub.com/javascriptallongesix)),
I was going to write my first long-form book from scratch. My previous books
were collections of essays with additional linking and filler material.

I resolved to write a trial book first, so I wrote CoffeeScript Ristretto. I
had a rough idea that the market for a CoffeeScript book was about 10% of the
market for a JavaScript book, so I didn't have big expectations for revenue,
but I figured I could gain experience writing the book and a lot of valuable
feedback.

The secret was, when I then published JavaScript Allongé, it was basically the
same book, just in JavaScript. The big differences had to do with the
differences between CoffeeScript and javaScript, obviously, but most of the
chapters were identical.

I found this process was a really big win, when JavaScript Allongé first hit,
it was already refined by all the feedback I got from CoffeeScript Ristretto.
If I was doing a software side project, I might take the same approach: Start
in a smaller market where I can refine the software and business, then
repurpose into the target market.

JM2C, YMMCV, &c.

Thanks for sharing your thoughts.

You might want to consider writing the book on leanpub, and then talking to a
traditional publisher to adopt the book. At least that's my plan for
[https://leanpub.com/perl6](https://leanpub.com/perl6) (a publisher has
approached me, though it's currently in a too early stage, so we've deferred
further discussions until version 1 of the manuscript is ready).

I believe you need to create a book on leanpub for that, which now costs
USD$99. Not terribly much, but a certain threshold that prevents me from just
throwing out ideas like this.

~~~
braythwayt
> I believe you need to create a book on leanpub for that, which now costs
> USD$99

Yes, that is a new "feature." However, IIRC, once you reach a certain
threshold of royalties, the $99 is waived. So,if I were starting today, I
still wouldn't pay it because my very first book would get me over the
threshold.

Now I had the benefit of having written a blog, so I had material and an
audience. But these are important things to have even if you don't pay $99 to
publish a book.

If you want to write a book, or start a software side-project, it is
enormously helpful to "prime the pump" by building your brand a little. Speak
at conferences, write a blog, be a thoughtful contributor on social media
sites where your eventual customers go for help.

If you do those things, you needn't worry about the $99 for your first book,
or whatever fee some captive app market charges you, &c.

Bit of a chicken-and-egg problem, but online reputations can be built over
time by plugging away, a little like gold-mining in MMORPGs...
