“Business operations software” covers so much ground it stops being useful. A project board, a chat app, a CRM, a timesheet, and an e-signature tool solve five separate problems for five separate people, and none of them substitute for each other. Buying one “ops suite” because it claims to do all five usually means a mediocre version of each and a great version of none.
So this page sorts by job, not by category label. Every fact below is pulled from our own reviews of these six tools, and every price is the vendor’s published figure at the time of writing. The clearest pattern across all six: the free tier is the real product for a small team in four of five categories, and the upgrade trigger is a specific feature, not a headcount tax.
Executive Answer
- Project management: Plaky. No user cap at all on Free — a real edge over Asana’s 10-person ceiling. Automations are Pro-only, $3.99/month.
- Team chat: Pumble. Free plan keeps unlimited message history and users, unlike Slack’s 90-day cutoff. Independent monitoring shows real outages, so weigh that against the price.
- CRM: Capsule CRM. Genuinely usable free tier — 250 contacts, 2 users — though we couldn’t independently verify paid pricing against a live vendor page.
- Time tracking: Clockify. Unlimited users and projects on Free, with no seat-count ceiling anywhere in this category’s usual playbook.
- E-signature, self-hosted: DocuSeal. Free and unlimited if you can run your own server and SMTP.
- E-signature, cloud-only: BoldSign. Cheaper per seat than DocuSeal’s cloud tier, with a more generous free plan at 25 envelopes a month.
Sort by Job
| Job | What it answers | Tool here | Free tier | Paid from |
|---|---|---|---|---|
| Project management | Who’s doing what, and by when? | Plaky | Unlimited users, boards, items | $3.99/user/mo |
| Team chat | Where does the team talk? | Pumble | Unlimited users, unlimited history | $2.49/user/mo |
| CRM | Who have we talked to, and what’s the deal stage? | Capsule CRM | 250 contacts, 2 users | ~$18/user/mo (third-party sourced) |
| Time tracking | Where did the hours actually go? | Clockify | Unlimited users and projects | $3.99/user/mo |
| E-signature (self-hosted) | Can I get a signature without a vendor holding the document? | DocuSeal | Unlimited, self-hosted | $20/user/mo (cloud) |
| E-signature (cloud) | Can I get a signature without running a server? | BoldSign | 25 envelopes/mo, 1 user | $5/user/mo (annual) |
Plaky, Pumble, and Clockify share a parent company, CAKE.com, and bundle at $12.99 per user monthly for Enterprise-tier access to all three. Price that before buying two separately.
The Tools In Detail
Plaky — project boards without a per-user tax
Plaky sits between Trello and Asana: cards-and-checklists simplicity, plus Kanban, table, and Gantt views switchable from the same board. The free tier includes unlimited spaces, boards, items, and users, with 6 custom fields per board and 10 MB of storage. Pro is $3.99 a month per user (annual) and adds unlimited custom fields, the Gantt view, automations capped at 1,000 actions a month, and private boards.
The gap between pitch and product is automations: marketed as a core feature, absent entirely below Pro. A 20-person marketing team can run its whole campaign pipeline on Free — Asana would start charging at 11 people — but gets zero recurring automation until someone pays. The other real limitation is the integration ecosystem, which still trails Trello and Asana’s marketplaces, plus a permissions quirk where only a space’s original creator can delete it. Full Plaky review.
Pumble — unlimited history, with a documented reliability catch
Pumble is a Slack-style chat app, also from CAKE.com, built around channels, threads, and calls. Its free tier does something almost nothing else in the category does: it keeps unlimited message history and unlimited users, plus 10 GB of shared storage. Slack’s free tier deletes history after 90 days and caps storage at 5 GB. Pro is $2.49 a month per user and unlocks group video for up to 50 people; Business, at $3.99, raises that to 100 and adds guest access for clients.
The catch isn’t price, it’s reliability. StatusGator, an independent uptime tracker, recorded more than 32 incidents on Pumble’s web app over roughly two years, and multiple reviewers separately report video calls failing to connect on the first attempt. For a text-first team on occasional 1:1 calls, that’s a manageable trade. For a team that lives in group video, test it first. Full Pumble review.
Capsule CRM — a real free tier, with a pricing transparency gap
Capsule tracks contacts, organizations, and a sales pipeline without the configuration overhead of an enterprise CRM. Free covers 250 contacts, 2 users, one pipeline, and 5 custom fields — genuinely usable, not a time-limited trial. Paid tiers run roughly $18 a user monthly at Starter up to $72 at Ultimate, adding automations and project management at Growth.
Worth flagging: Capsule’s pricing page didn’t return static paid-tier figures when checked directly, consistent with an interactive calculator rather than published numbers. The Starter-through-Ultimate prices are corroborated across third-party sources, but that’s weaker than confirming a number straight from the vendor. Confirm current pricing before budgeting. Support also draws real complaints — one review called it “bad, really bad” — and reporting is fine for basics but frustrating for custom dashboards. Full Capsule CRM review.
Clockify — the free tier with no ceiling anywhere
Clockify tracks time against a project and task, then rolls it into reports by person, project, or date. What sets it apart isn’t the tracking mechanism, which is standard for the category — it’s that the free tier supports unlimited users, unlimited projects, and unlimited tracking, where competitors like Toggl Track cap free usage at a handful of seats. A 15-person agency can run its whole time-tracking workflow on Free indefinitely; the upgrade trigger is a specific feature, not team growth.
Those features are real, though. Invoicing sits behind Standard at $5.49 a seat monthly, not Basic. Budget forecasting and GPS or screenshot tracking for field teams live behind Pro at $7.99. The honest limitation is polish, not pricing: desktop-to-web sync lag can create duplicate time entries, and the mobile app is the weakest part of the product by reviewer consensus. Full Clockify review.
E-signature head-to-head: DocuSeal vs. BoldSign
These two are direct competitors solving the same job at opposite ends of one trade-off: who controls the infrastructure.
DocuSeal is open-source under AGPLv3. Its self-hosted Open Source tier is genuinely free with no envelope cap, indefinite retention, and full source access to audit or modify — you provide the server and your own SMTP, and support is community-only via GitHub. Its hosted Cloud Basic tier is free but capped at 10 signature emails a month; Cloud Pro jumps to $20 a user monthly for unlimited requests, payment collection, and SSO. Full DocuSeal review.
BoldSign takes the opposite bet: no self-hosting at any price, but a more generous free tier at 25 envelopes a month and a paid entry price of $5 a user monthly billed annually — a quarter of DocuSeal’s cloud rate. Every paid plan includes full audit trails standard, not gated to a top tier. The real constraint is that Essential, the free tier, supports exactly one user, and branding and customization options trail DocuSign’s. Full BoldSign review.
The decision is less about price than who’s holding the document. If compliance requires signed contracts never leave infrastructure you control, DocuSeal’s self-hosted tier is the only option here that satisfies that outright. If you just want cloud signing without a server to maintain, BoldSign’s $5-a-month entry price and 25-envelope free tier both beat DocuSeal’s cloud numbers.
How to Choose
- Name the job before the category. “Business operations software” isn’t a purchase decision. “Where does my team keep the pipeline stage of a deal” is.
- Exhaust the free tier first. Four of six tools here — Plaky, Pumble, Capsule, Clockify — have free plans that are the actual product for a small team, not a crippled trial.
- Check who’s licensing per seat versus per usage. BoldSign’s Enterprise API bills per envelope, sensible only if your own end users are the signers. Everything else here bills per user.
- Decide who controls the data before comparing price. DocuSeal’s self-hosted tier and BoldSign’s cloud-only model aren’t really competing on cost — they answer different questions about where a signed document lives.
- Price the CAKE.com bundle before buying two of its tools separately. Plaky, Pumble, and Clockify bundle at $12.99 a user monthly for Enterprise access to all three.
Frequently Asked Questions
What’s the best free project management tool?
Plaky, for a team that doesn’t need automations yet. Its free tier has no user cap, unlike Asana’s 10-person ceiling, and includes table, Kanban, and Gantt views. Automations are entirely absent below the $3.99-a-month Pro tier.
Is Pumble’s free plan actually free forever, or a trial?
A permanent tier, not a trial — unlimited users and message history, verified against Pumble’s own pricing page. The limits are group video (1:1-only on Free) and a documented pattern of outages in independent uptime monitoring, worth weighing against the price.
Can a small team run its CRM entirely on Capsule’s free plan?
Yes, up to 250 contacts and 2 users, which covers most solo or two-person consultancies. Contact counts climb faster than expected once past and inactive contacts are included, so know roughly where you sit first.
Do I need to pay for time tracking at all?
Not for tracking and reporting — Clockify’s free tier has no user or project ceiling. You need a paid tier only for invoicing (Standard, $5.49/seat/mo) or budget forecasting and GPS tracking (Pro, $7.99/seat/mo).
Should I self-host my e-signature tool or use a cloud plan?
Self-host with DocuSeal if you can run a server and your own SMTP, and data control matters more than convenience. Use BoldSign’s cloud plan if you’d rather pay $5 a user monthly than manage infrastructure — it’s cheaper per seat than DocuSeal’s cloud tier and has a bigger free-tier allowance.
Is the CAKE.com bundle worth it over these tools separately?
Only if you’d genuinely use Enterprise-tier features across at least two of Plaky, Pumble, and Clockify. At $12.99 a user monthly for all three, it beats paying for two separately at Pro or Business — but it’s wasted spend if the free plans would otherwise cover you.
How We Assessed These
Each tool above has been reviewed individually, and every price and free-tier limit is pulled from that review, sourced from the vendor’s own pricing page unless noted. Capsule CRM’s paid-tier pricing is the exception: we could not retrieve static dollar figures directly from its pricing page, so those numbers are corroborated third-party estimates, flagged as such rather than presented as confirmed. Reliability claims about Pumble come from StatusGator’s independent incident monitoring, not vendor marketing.
We don’t rank these six against each other with one combined score, because they answer five different questions and a blended ranking would obscure that rather than clarify it.
Disclosure: our reviews of Plaky, Pumble, Capsule CRM, and Clockify contain affiliate links — if you sign up through them we may earn a commission at no extra cost to you. DocuSeal and BoldSign currently carry no affiliate relationship. None of this affects the assessments above.
