Best Free Todo Apps for Solo Founders & Indie Hackers

Solo founders and indie hackers have a different todo-app problem than corporate teams. You are not coordinating a sprint with eight engineers. You are trying to decide whether to ship the landing page tonight or fix the auth bug, and whether the cold-email script is worth two days of effort.

The standard listicle answer ("Asana free tier, Trello free tier, ClickUp free tier") solves a problem you do not have. Those apps optimise for team collaboration and gate the useful features behind a paid seat. What you need is a fast capture surface, a way to see what is on today, and ideally a way to prioritise so the "important" stuff does not get buried under the "loud" stuff.

I tested ten apps against four criteria that actually matter when you are a single human shipping product:

• Free tier you will not outgrow in a quarter (i.e. not the bait-and-switch of "5 projects, then $7/mo")
• Capture friction under three seconds from "I just thought of it" to "it is in the system"
• Works offline or anonymously so you can use it without a signup ritual
• Prioritisation built in, not bolted on, because the bottleneck for solo founders is choosing what NOT to do

Why do solo founders need a different kind of todo app?

Team-oriented tools (Asana, ClickUp, Linear) are designed around the assumption that several people need to see the same task. That is overhead for one person. You do not need @mentions, you do not need approval flows, you do not need a daily standup view.

Solo workflows benefit from three things instead: fast capture (so ideas do not leak), a visible "today" view (so you do not start the day deciding what to start), and a way to weigh impact against effort (so you stop polishing the favicon while the payment integration is broken). Most of the apps below cover the first two. Only a few cover the third, which is why a tool like a built-in impact-effort matrix is worth its weight when you have ten ideas and one engineer (you).

How does this list compare at a glance?

1. Codersera Task Tracker — the no-signup pick

What it is. A free browser-based task tracker at codersera.com/tools/todo-tracker built around the four-lane Kanban (Backlog → Today → Doing → Done) plus a List view and an embedded impact-effort matrix. The same data, three views, toggled from the toolbar.

Why it earns the top slot for solo founders. Three reasons. First, there is no signup. Open the URL, start typing tasks, your data persists in IndexedDB. Sign in with Google later if you want cross-device sync — your local tasks merge into the cloud copy on first sign-in (last-write-wins). Second, the impact-effort matrix is the same data as your Kanban, not a separate tool. You can drag a task onto a 2×2 grid (Quick Wins / Major Projects / Fill-Ins / Time Wasters), and it shows up tagged on the Kanban with quadrant context. This is exactly the wedge solo founders need: a way to stop spending two hours on a Quick Win that is actually a Time Waster.

What it does not do. No native mobile app — it works in mobile Safari and Chrome but you do not get a home-screen icon with offline-first sync the way Todoist or TickTick give you. No recurring tasks (calendar covers that better). No due-date reminders (deliberate — most solo founders use calendar reminders, not todo-app pings). If those gaps are dealbreakers, pick TickTick.

Free-tier reality. Free forever, all features, no upsell. The signed-in cloud sync is also free. There is no premium tier.

Use it when. You want one URL that captures everything, lets you decide what to ship today, and shows you which big bets are worth your next two weeks. Pair it with Codersera Focus Timer for the actual execution.

2. Super Productivity — the open-source developer pick

What it is. Open-source desktop and web todo app (MIT-licensed, ~17k GitHub stars) that combines tasks, time tracking, timeboxing, and a Pomodoro timer. Pulls issues directly from GitHub, GitLab, Jira, and OpenProject — solo developers can treat their issue tracker as the source of truth and use Super Productivity as the daily-execution layer.

Why solo developers love it. It is genuinely 100% free with zero ads, zero accounts, and zero data collection. Your data lives on your machine (or syncs via your own Dropbox / WebDAV). The GitHub integration is the killer feature: any issue assigned to you in any repo shows up in your inbox, and time spent on it gets logged back to the issue automatically.

Weakness. The UI is dense. There are eleven sidebar tabs, three views, and a worklog. If you came from Things 3 expecting calm, you will bounce. Plan to invest 30 minutes learning it.

Use it when. You are shipping code and your day-to-day is GitHub issues + Pomodoros. Skip if you are not a developer; the audience-fit is sharp.

3. TickTick — the best paid tier if you outgrow free

What it is. Cross-platform task app with a built-in Pomodoro timer, habit tracker, calendar view, and an Eisenhower matrix tab. Free tier is generous; Premium is $35.99/year (about $3/mo), which is roughly half of Todoist Premium.

Why it wins for many solo founders. TickTick is the closest thing to "one app that replaces three apps." If your existing stack is Todoist + Google Calendar + a separate Pomodoro app + a habit tracker, TickTick collapses that into one URL. The calendar view shows your Google Calendar events and TickTick tasks on the same screen, which is the killer feature for time-blocking your week.

Free-tier reality. The free version is usable as a daily driver: unlimited tasks, basic calendar, Pomodoro timer, board view. You hit the paywall when you want the calendar to sync with Google Calendar (Premium), advanced filters, or more than five habits in the habit tracker.

Weakness. Natural-language input is weaker than Todoist's — you cannot just type "file taxes in two days," you have to set the date explicitly. Mobile and desktop apps require accounts.

4. Todoist — the capture king

What it is. The pioneering modern todo app. Excellent natural-language input ("submit invoice every Friday at 4pm" just works), beautiful cross-platform clients, fast capture via keyboard shortcut on every device.

Why solo founders pick it. Capture friction is genuinely zero. Cmd-Shift-A on Mac, type the task in natural English, the date and recurrence parse correctly, done. If your bottleneck is "I keep losing ideas," Todoist's capture surface is best-in-class.

Free-tier reality (read this carefully). Todoist's free tier caps you at 5 personal projects. That sounds fine until you realise a typical solo founder has "main product," "side experiment," "newsletter," "customer pipeline," "home life" — and you are already at five. Adding a sixth project requires Premium at $48/year. The 5-project cap is the single biggest gripe in every Todoist review of 2026.

Use it when. Capture speed is your number-one criterion and you are happy to pay $48/year once you outgrow free.

5. Notion — when tasks and docs should live in the same place

What it is. Workspace-as-database. You can build a custom task system with whatever fields, views, and automations you want. Free for personal use with unlimited pages.

Why solo founders use it anyway. If your product specs, customer notes, marketing plans, and tasks all need to cross-reference, Notion lets you build one workspace that owns everything. Templates like Thomas Frank's Ultimate Brain give you a pre-built GTD setup if you do not want to roll your own.

The structure tax. Notion is slow to capture and slow to load on mobile. Adding a task takes 4–6 clicks. The blank-canvas problem hits hard: you spend a weekend designing your "system" and the next weekend redesigning it. Several solo founders we surveyed had switched from Notion → Todoist or → Codersera Task Tracker specifically because they were spending more time tending the system than executing tasks.

Use it when. Your docs and tasks are tightly coupled (e.g. product specs that link to engineering tasks) and you are happy to invest 2-3 hours upfront in the setup.

6. Things 3 — the calm, Apple-only paid option

What it is. Beautifully designed task app from Cultured Code. Mac is $49.99, iPhone $9.99, iPad $19.99, all one-time. No subscription, no account, syncs via Things Cloud.

Why solo founders love it. It is the calmest task app on the market. Today / Upcoming / Anytime / Someday is the entire mental model. No Kanban, no matrix, no Pomodoros. Just a list that respects your attention. Many seasoned solo founders cite Things 3 as the app they came back to after trying everything else.

Why it is not free. It is on this list as a comparison anchor, not a free pick. ~$80 total across Mac and iPhone gets you a tool you will use for ten years. Most solo founders should consider that a bargain compared to $48/yr Todoist or $36/yr TickTick.

Weakness. Apple ecosystem only. No Windows, no Linux, no Android, no web. If you switch platforms, your data does not.

7. Microsoft To Do and Apple Reminders — the built-ins you forget about

What they are. Free task apps bundled with their respective operating systems. Apple Reminders is on every iPhone/Mac out of the box; Microsoft To Do is the spiritual successor to Wunderlist and ships with Windows and Microsoft 365.

Why they are underrated. Capture is zero-friction because they are already on your device. "Hey Siri, remind me to email Sarah at 3pm" works instantly. No install, no signup beyond your OS account.

Apple Reminders got a major upgrade with smart lists, tags, and subtasks. For an Apple-only solo founder it is genuinely competitive with paid apps. Microsoft To Do is more basic but integrates with Outlook and Microsoft 365.

Weakness. Lock-in. Switch operating systems and you start over. No Kanban, no prioritisation matrix.

8. Linear (free) — the developer issue tracker with a todo vibe

What it is. Keyboard-first issue tracker built by ex-Coinbase / Airbnb engineers. Beautiful, fast, opinionated. The free tier supports unlimited members, 2 teams, and 250 active issues.

Why solo founders use it. If you are a technical solo founder shipping a SaaS product, Linear's mental model (issues → cycles → projects) maps cleanly onto how you think. The keyboard shortcuts are second to none. It is the closest a SaaS tool comes to feeling like Vim.

The 250-issue cap. This is the single number that decides Linear's free-tier fit. If you are shipping weekly, you will hit 250 issues in about 2 months and need to either close old issues or move to the $8/seat Basic plan.

Use it when. You think like an engineer about your work, prefer keyboard to mouse, and your sprint cadence is the unit of progress. Skip if your todo list is mostly non-engineering work (marketing, sales, hiring).

9. Tweek Calendar — the weekly-rail pick

What it is. A minimalist weekly planner that looks like a paper diary turned digital. One row per day of the week, tasks beneath. No projects, no tags, no priorities. Pro is $4/mo and adds Google Calendar sync, recurring tasks, and reminders.

Why some solo founders swear by it. If you think in weeks ("this week I need to ship the landing page, get 3 customer calls, and write one blog post"), Tweek's UI is the model. The lack of features is the point — you cannot waste time tending the system.

Free-tier reality. Generous free tier. The Pro upsell ($4/mo) is honest — calendar sync and recurring tasks are the only features behind it.

Weakness. If you have more than ~10 tasks at any time, the weekly grid breaks down. No backlog. No "someday" list. Pair with a separate inbox if you have lots of ideas.

10. Trello / Asana / ClickUp — the team tools most solo founders pick and regret

What they are. Kanban-board-led team task managers with generous free tiers for individuals.

Why most solo founders churn off them within 90 days. They are designed for teams. The cognitive overhead of assignees, due-date pickers, automations, and integrations is built for a group of five, not one. You drag cards in circles to feel productive rather than shipping.

The Trello caveat. Free Trello is fine for one Kanban with under 50 cards. Want a timeline view or a second Power-Up? Paywall. Most solo founders are better served by a tool that gives them list + Kanban + matrix for free, which is the gap Codersera Task Tracker targets.

How do I pick the right one?

Walk down this decision tree until something fits:

1. Need it to work in 10 seconds, no signup, browser-only? → Codersera Task Tracker
2. Live in GitHub / Jira / GitLab and want time tracking? → Super Productivity
3. Want one app for tasks + calendar + Pomodoro + habits? → TickTick
4. Capture speed is everything and you do not mind 5 projects? → Todoist (free)
5. Already living in Notion for docs? → Notion (extend with Ultimate Brain template)
6. All-Apple, hate subscriptions, value calm? → Things 3
7. Already on Windows / Outlook? → Microsoft To Do
8. You think like an engineer and ship in cycles? → Linear (free, until 250 issues)
9. Plan in weeks, not lists? → Tweek Calendar

A small but uncomfortable observation: the apps your founder friends recommend are often the apps they aspire to use, not the ones they actually use. The honest answer for most solo founders is: pick something free and frictionless, use it daily for two weeks, then upgrade only if you have hit a specific limit. The cost of "trying" Codersera Task Tracker or Super Productivity is zero; the cost of trying Things 3 is $80.

What about the matrix (the thing no todo app mentions)?

Most todo lists fail solo founders not because they cannot capture tasks but because they cannot prioritise them. The Impact-Effort Matrix is the simplest tool for this: plot each task on a 2×2 grid of "how much will this matter" vs "how hard is this to do." Quick Wins (high impact, low effort) come first. Time Wasters (low impact, high effort) get killed.

Only two of the apps in this list have it built in: TickTick's Eisenhower-matrix tab (Premium) and Codersera's Impact-Effort Matrix (free, no signup, same data as the Task Tracker). Everyone else expects you to keep the prioritisation framework in your head. That is fine until you have 30 tasks and 8 of them feel urgent. Then it stops being fine.

FAQ

What is the best free todo app for solo founders in 2026?

For free + no signup + browser-based, Codersera Task Tracker is the lightest fit. For free + mobile + natural-language capture, TickTick free tier. For free + open source + developer integrations, Super Productivity.

Is Todoist free worth it for solo founders?

The 5-project cap on Todoist's free tier is the single biggest constraint. Solo founders typically hit it inside a quarter (one project for the product, one for marketing, one for finance, one for personal, one for ideas — already at the cap). Upgrade to Premium ($48/year) or pick a tool with no project limit.

Do I really need a separate prioritisation tool?

You need a framework, not necessarily a separate tool. The Impact-Effort Matrix takes 5 minutes to learn and replaces gut-feel prioritisation. If your todo app does not have it built in, you can run it on paper, in a spreadsheet, or in Codersera's free Impact-Effort Matrix.

What is the lightest no-signup todo app?

For browser-only, no-account workflows: Codersera Task Tracker, kanban.fit, FreeKanban, TodoListMe, and Flask Lists all open and work immediately. Of those, Codersera Task Tracker is the only one with Kanban + List + matrix views and optional cloud sync if you decide you want it later.

Should solo founders use Linear or a regular todo app?

Linear if your daily work IS shipping code in cycles and you want issue-tracker rigour. A regular todo app (Codersera Task Tracker, Todoist, TickTick) if a meaningful chunk of your day is marketing, sales, hiring, or operations, where Linear's issue-tracker mental model is overkill.

Is Notion good as a todo app?

Notion is great as a workspace, mediocre as a pure todo app. Capture friction is high (4–6 clicks vs 1 keystroke in Todoist). If your tasks need to live next to your docs and customer notes, Notion is worth the trade-off. If your tasks just need to be tracked and executed, use a dedicated todo app.

What if I want focus / time-blocking alongside my todo list?

Pair your todo app with a focus timer. TickTick has one built in (Premium). For everyone else, Codersera Focus Timer is free, no signup, opens in a browser, with ambient soundscapes and a soft chime when the block ends. Drop the URL on your tab bar and run a 50-minute block against the top task on your Kanban.

The bottom line

Most solo founders pick a todo app that was designed for a 50-person engineering team, then wonder why they spend more time tending the system than shipping product. The fix is small: choose a tool that respects your actual scale (one human, not fifty), that you can open without a 90-second signup ritual, and that has prioritisation built in.

Codersera Task Tracker was built specifically for this audience because the standard listicle did not have an honest answer for it. Open the URL, type your first three tasks for tomorrow, and decide in two weeks whether it is the system you want. The cost of trying is exactly zero.
