Best subreddits for Devtools

Subreddits for founders building developer tools -- IDEs, CLIs, SDKs, observability, infra, and AI dev tools -- where the actual buyers and users hang out.

01r/programming6.5M members
Working programmers and engineers across stacks
Largest serious-engineering audience -- where dev tool announcements actually get discussed when the post teaches something technical.
What to post
Share deep technical write-ups about how your tool solves a specific engineering problem; ask for architecture or design critique with concrete tradeoffs.
What to avoid
Launch links, marketing-style posts, blogspam, and 'I built X' threads with no technical depth.
Key rule
Posts must be substantive technical content, not news, opinion pieces, or promotion.
02r/devops450k members
DevOps and infrastructure operators
Direct fit for infra, observability, CI/CD, and platform-engineering tools -- the operators who pick and run them.
What to post
Ask about deployment, reliability, or automation problems with real context; share postmortems or lessons from running infra tools in production.
What to avoid
Vendor spam, market surveys, undisclosed affiliation, and 'best tool for X' bait.
Key rule
Link posts need commentary and discussion context, not just a URL.
03r/webdev3.2M members
Web developers and technical builders
Fits dev tools targeting web developers -- frameworks, bundlers, frontend libraries, dev servers, and DX tooling.
What to post
Ask for critique on a developer experience decision; share build lessons from solving a specific web-dev pain.
What to avoid
Commercial launch promotion, low-context tool demos, and 'check out my framework' posts.
Key rule
Vague support questions and product launches go to more appropriate subreddits.
04r/ExperiencedDevs350k members
Senior engineers and engineering leaders
Useful for dev tool founders selling to senior ICs and engineering managers -- the actual decision-makers on tool adoption.
What to post
Ask senior engineers about adoption barriers for a class of tooling; share lessons learned from selling or rolling out dev tools inside teams.
What to avoid
Tool announcements, career-change posts, and questions that fit r/cscareerquestions better.
Key rule
Posts should be from or for experienced developers; junior career questions are removed.
05r/SaaS704k members
SaaS founders and operators
Useful when the dev tool is a SaaS product with real pricing, onboarding, retention, and PLG questions.
What to post
Ask how dev-tool SaaS founders price by seat vs usage; share activation lessons specific to developer audiences.
What to avoid
Launch links, free-trial pitches, and generic SaaS advice.
Key rule
Posts need a clear SaaS angle, not generic entrepreneurship or broad business news.
06r/opensource240k members
Open-source maintainers, contributors, and users
Fits dev tools with an open-source core, community questions, licensing, governance, and OSS-to-SaaS conversion.
What to post
Ask about OSS governance, sustainability models, or contributor pipelines; share lessons from running an OSS project alongside a commercial offering.
What to avoid
Closed-source product pitches, licensing flame bait, and tool promotion outside relevant threads.
Key rule
Posts should focus on open-source software, communities, and practices.
