r/sysadmin
IT administrators and internal operations staff
- Size
- Very large
- Buying intent
- High
- Promotion
- Conditional
Large, extremely active, and full of people for whom buying software is a routine part of the job rather than an event. Skews toward Windows and enterprise environments, which distinguishes it sharply from the Linux-leaning communities elsewhere on this list.
Members are long-tenured and the community has strong institutional memory. Vendors who behave badly are discussed for years, and vendors who show up consistently and help are afforded genuine goodwill.
What people actually post
The procurement question
What to buy, with a budget and a constraint already stated. Direct and frequent.
The migration thread
Moving off something, usually because of a price rise or an acquisition. Names the incumbent and the trigger.
The war story
Enormously popular, entirely social, and not a place to sell anything.
What people get wrong about it
Outsiders read the humour posts as the culture. Underneath it is one of the most experienced technical populations on the platform.
Can you promote in r/sysadmin?
Self-promotion is restricted and reports are frequent. The route in is being useful in threads about the problem rather than about the category, and disclosing plainly when you mention what you built.
What gets you removed
Assuming everything runs in a cloud. A large share of members maintain hardware older than most startups.
A good first contribution
Answer a Windows or hybrid infrastructure question. The community skews far more enterprise than the Linux-heavy subreddits and expertise there is scarcer.
Products that fit here
- Endpoint management and monitoring
- Backup and disaster recovery
- Identity, access and directory tooling
- Ticketing and internal documentation
What does not work
Anything assuming a cloud-native greenfield environment. A large share of members run hybrid infrastructure with hardware older than your company.
Timing
Budget cycles in Q4 and licence renewal anniversaries drive most purchasing threads.

Where this fits in a wider plan
r/sysadmin appears in our list of the best subreddits for developer tools, which sets it against the other communities worth watching in that market. If you are starting from nothing, the six-week plan in finding your first 100 users covers how to build standing before you mention a product at all.
Watch r/sysadmin without reading it.
Lidar reads it every day, scores each post against what your product does, and sends you the ones worth answering. Along with the rest of engineering and infrastructure.
