What are the 5 tools you simply couldn't do your work without?
This could be related to your industry, or even a side project you're working on.
Here are my 5 (I couldn't function without them):
Grammarly – proofreading my texts, not just posts, but also client communication
ChatGPT / Claude – mostly brainstorming, help with copy, and summarising
Figma – I can put the basic graphics together quickly.
Translator – sounds incredibly old-school, but English is not my mother tongue
Gmail – and not only for communication, but also for storing ideas and sending myself email reminders for posts
[and soon one more that I am working on – SafeLimit – prevents me from being banned on LinkedIn, so I will not lose my account.]
What are your five?

solo builder, so my five do a lot of heavy lifting:
1. claude code, basically my engineering team at this point
2. fly.io, tiny vms that scale to zero, perfect for small services
3. neon, postgres i never have to babysit
4. resend, transactional email that just works
5. smolanalytics. full disclosure, this one is mine. i built it because i kept shipping blind: you ask your analytics questions in plain english from your editor and it answers with computed numbers, not hallucinated ones. it's open source, so calling it a tool i couldn't work without is at least honest
honorable mention: a paper notebook for everything no app has fixed yet. what's the most old-school thing on everyone's list?
Just 3 atm...

My 5:
1. Xcode, Zed, Terminal for software development
2. Figma, Final Cut, Ableton for design, video & music production
3. Codex for agentic workflows
4. Gmail, Telegram for communication
5. tinypad for bookmarks & links
I've been exploring what tools can help reduce the time I spend on frontend UI design.
my 5:
- Claude code
- ChatGPT
- Docker
- Supabase
- Vercel
Great list, Nika! Totally get the Gmail reminders and Figma for quick visual fixes.
Here are the 4 I absolutely need to keep my workflow running:
Claude – My go-to for brainstorming, copy, and working through ideas.
Brevo – Crucial for handling all our email marketing and automation.
Canva – For throwing together clean marketing assets and visuals quickly.
Outlook & Teams – The essential hub for all client comms and staying aligned.
My 5:
1. Claude Code - my co-founder #2
2. Claude Code - my co-founder #3
3. Claude Code - my co-founder #4
4. Claude Code - my co-founder #5
5. Obsidian - sync my thoughts between devices, offload my brain
As a solo dev I need to leverage the agentic tools.
Solo founder building HealthOS — voice biomarkers + on-device AI for health coaches. My 5:
Claude Code — I'd describe it as a junior CTO that never sleeps. I talk to it like a co-founder, it keeps the codebase consistent, drafts docs, and catches things I miss. Easily my #1.
2. Cursor — for when I want to stay in editor mode and not context-switch to terminal
3. Notion — single brain dump for everything: research notes, ICP docs, weekly reviews
4. Linear — solo sprints feel more real when something is tracking your commitments
5. SQLite — technically a database, but for a solo founder it's the most freeing "tool" in the stack: no server, no ops, just a file that scales further than you'd expect
The common thread for me: tools that compress the cognitive load of doing everything yourself. Curious if others on that solo/small team journey have found the same.
I use, in order:
Microsoft Edge (browser)
Gmail
Google Calendar
ChatGPT
Android phone (Google Pixel 9 XL Pro)
