16 AI Tools Indie Hackers Actually Use in 2026
Indie hackers don’t buy tools to look busy — a tool either saves real hours or gets cut. After the honeymoon of AI app builders wears off, the stack that survives is small, cheap, and does actual work. This is that stack.
We’ve grouped it by the three jobs every indie hacker juggles: building the product, getting it in front of people, and running the operational grind that never shows up in a launch tweet.
Ops: the tools that buy back your week
You are the founder, the support desk, the scheduler, and the bookkeeper. The ops tools matter most because they’re the ones you’d otherwise have to hire for.
1. Carly — your AI executive assistant
Carly is an AI executive assistant that lives in email and handles your inbox, calendar, scheduling, and business coordination. No app to install — you CC it on a thread and it books the call, sends the follow-up, and keeps the thread moving. For a solo founder, it replaces the assistant you can’t yet justify hiring.
What makes it fit the indie-hacker mindset: from the Carly dashboard you build your own agents, each with a dedicated email address, custom instructions, and memory, plus 200+ integrations across 40+ categories — calendars (Google, Outlook), CRM (HubSpot, Salesforce, Attio), messaging (Slack, Discord), and project management (Asana, Linear, Monday). Common builds: a demo-scheduling agent, a lead-response agent, an invoice-follow-up agent. Carly starts at $35/month, with a free group-scheduling grid and booking pages you can use before you pay anything. More context in our AI tools for solopreneurs guide and how to build AI employees.
2. Fathom or Fireflies
Fathom and Fireflies record, transcribe, and summarize your calls so you can be present in customer conversations instead of scribbling notes. Feed the summaries into your CRM.
3. Stripe
Stripe for payments — non-negotiable. Its billing and revenue-recovery features handle the money plumbing so you don’t build it yourself.
Build: shipping the product
4. Cursor
Cursor is the AI code editor most technical indie hackers live in. It keeps you in control of the codebase while the AI does the heavy lifting.
5. Lovable
Lovable builds end-to-end apps including the database, with output polished enough to demo. Great for the non-code parts of your product or a quick marketing site. Runs on message credits.
6. Replit
Replit’s Agent 3 builds and deploys full-stack apps in a glass-box environment where you keep access to the code. Effort-based pricing.
7. v0 and Bolt.new
v0 for React/Next.js UI, Bolt.new for full-stack prototypes in the browser. Both are credit-based and best for the front end you want fast. See our no-code AI automation tools list for adjacent builders.
Marketing: getting users
8. Claude and ChatGPT
Claude and ChatGPT draft your copy, launch posts, and cold emails. Draft with them, edit in your voice — AI-default copy is easy to spot and easy to ignore.
9. Typefully
Typefully is where indie hackers build in public. Schedule threads, track what lands, and turn your build log into distribution.
10. Ahrefs
Ahrefs shows you the keywords worth targeting and who’s ranking for them. SEO is the compounding channel indie hackers can actually afford.
11. Resend
Resend sends your transactional and marketing email with a developer-first API. Pair it with a Carly agent to handle the replies those emails generate.
Customer support and analytics
12. Intercom Fin
Intercom Fin answers common support questions automatically, so a one-person shop can offer real coverage without living in a help desk.
13. Plausible or PostHog
Plausible for simple, privacy-friendly web analytics; PostHog when you want product analytics, replays, and feature flags together.
Glue and automation
14. Zapier
Zapier connects the apps that don’t talk to each other, running fixed workflows on triggers.
15. Make
Make is the more visual, more flexible sibling of Zapier for multi-step automations.
16. Carly agents for the judgment calls
Fixed automations break the moment a situation needs a decision. A Carly agent reads the context and acts — “if the customer asks to reschedule, find a new slot and update everyone” is an instruction, not a rigid flow. That’s the difference between an automation and an assistant, which we unpack in AI app builders vs AI assistants.
The 4-tool minimum
If you’re just starting and want the smallest stack that works:
| Job | Pick | Why |
|---|---|---|
| Build | Lovable or Cursor | Ship the MVP |
| Ops | Carly | Inbox, calendar, follow-up |
| Payments | Stripe | Take money on day one |
| Distribution | Typefully | Build in public |
Everything else is an upgrade you add when a specific pain gets loud enough. The pattern that separates indie hackers who ship from ones who stall: they automate the ops early so the building never stops.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
