CleanChart is faster for static charts you put in reports and presentations. Flourish is stronger for animated, interactive visualizations you embed on the web. This comparison covers every meaningful difference so you can pick the right tool without wasting time on the wrong one.
Both tools turn raw data into charts without coding. But they solve different problems. Flourish is built for data storytelling — animated transitions, scrollytelling templates, and interactive embeds for editorial content. CleanChart is built for speed — upload a file, pick a chart type, export a publication-ready image in under two minutes.
We build CleanChart, so we are upfront about where Flourish is the better choice. If you have already decided to leave Flourish and want alternatives, see our separate best Flourish alternative guide. This post is for people still deciding.
Quick Verdict: Which Tool Should You Use?
Use CleanChart if your chart ends up in a PDF, slide deck, thesis, or printed report. Use Flourish if your chart lives on a webpage with hover effects, animations, or scrollytelling.

| Animation | No (static output) | Yes (core strength) |
| Input formats | CSV, Excel, JSON, TSV, XML, YAML, Markdown, Numbers | CSV, paste, Google Sheets |
| Export formats | PNG (300 DPI), SVG | PNG (paid), SVG (paid), embed code |

Where CleanChart Wins
CleanChart has clear advantages in five areas.
1. Speed and simplicity
CleanChart has no account creation, no template selection maze, and no project management dashboard. You upload a file, choose a chart type, adjust settings, and export. The entire flow takes under two minutes. Flourish requires account creation, project setup, and template selection before you see your first chart — fine for teams that use it daily, friction for anyone making a quick one-off chart.
2. Data privacy
CleanChart processes everything in your browser using JavaScript. Your data file is read locally, the chart renders locally, and the export downloads to your device. Nothing is transmitted to any server. Flourish uploads and stores your data on its servers, which is necessary for hosting interactive visualizations but concerning for sensitive data. If you work with confidential financials, HR records, patient-adjacent research data, or anything under GDPR restrictions, CleanChart's architecture removes the compliance question entirely.
3. Input format support
CleanChart accepts eight file formats natively: CSV, Excel (.xlsx/.xls), JSON, TSV, XML, YAML, Markdown tables, and Apple Numbers. Flourish primarily supports CSV and pasting from a spreadsheet. If your data comes from an API response (JSON), a configuration export (YAML/XML), or documentation (Markdown), CleanChart handles it without manual conversion. See our JSON to chart guide for an example of this workflow.
4. Analytical chart types
CleanChart includes specialized chart types that Flourish does not offer:
- Gantt charts for project timelines
- Bullet charts for KPI-vs-target displays
- Pareto charts for 80/20 analysis
- Gauge charts for single-metric dashboards
- Candlestick charts for financial OHLC data
- Step charts for discrete interval data
These chart types serve analysts, project managers, and financial teams — users who need functional charts, not animated stories.
5. Pricing for occasional users
Flourish's free tier adds a watermark to every chart. Removing it starts at $63/month (billed annually), which is $756/year. CleanChart offers pay-per-chart pricing: $7 for 10 charts, $15 for 25, or $25 for 50. If you make fewer than 50 charts per year, CleanChart costs a fraction of Flourish. There is no subscription to cancel or forget about.
Where Flourish Wins
Flourish is genuinely better in three areas, and we think it is important to acknowledge that honestly.
1. Animation and interactivity
Flourish's animated transitions, hover effects, and scrollytelling features are best-in-class. If you are building an interactive data story for a news article, annual report microsite, or social media campaign, Flourish delivers capabilities that CleanChart does not attempt. CleanChart produces static images. If your chart needs to move, Flourish is the right tool.
2. Web embedding
Flourish provides embed codes and hosted URLs for every visualization. You can drop a Flourish chart into a CMS, blog post, or web application with a single line of code. CleanChart exports downloadable image files (PNG, SVG) — ideal for documents but not for live web embeds.
3. Narrative chart types
Flourish offers templates CleanChart does not: animated bar chart races, parliament charts, election maps, sports brackets, 3D globe maps, and network graphs. These editorial templates are purpose-built for storytelling and are a core reason journalists and communications teams choose Flourish.
Who Should Use Which Tool?
| User type | Recommended tool | Why |
|---|---|---|
| Students / researchers | CleanChart | No account, no watermark, 300 DPI export, browser-only privacy for IRB compliance |
| Journalists / editorial teams | Flourish | Animation, scrollytelling, embed codes for CMS |
| Business analysts | CleanChart | Fast static charts for decks and reports, pay-per-chart pricing |
| Marketing / comms teams | Both (depends on output) | Flourish for animated web content, CleanChart for static reports and whitepapers |
| Project managers | CleanChart | Gantt charts, bullet charts, and other PM chart types not available in Flourish |
| Financial analysts | CleanChart | Candlestick charts, privacy for proprietary data, financial visualization support |
Chart Type Comparison
Both tools support standard chart types (bar, line, pie, scatter, area, donut). The differences appear in specialized types:
| Chart type | CleanChart | Flourish |
|---|---|---|
| Bar / Line / Pie / Scatter | Yes | Yes |
| Area / Donut / Bubble | Yes | Yes |
| Heatmap / Treemap / Box Plot | Yes | Yes |
| Radar / Spider chart | Yes | Yes |
| Sankey diagram | Yes | Yes (Alluvial) |
| Gantt chart | Yes | No |
| Bullet chart | Yes | No |
| Pareto chart | Yes | No |
| Gauge chart | Yes | No |
| Candlestick chart | Yes | No |
| Step / Combo / Sparkline | Yes | Limited or No |
| Bar chart race (animated) | No | Yes |
| Parliament chart | No | Yes |
| Election / Choropleth map | No | Yes |
| Network graph | No | Yes |

Data Workflow Comparison
The two tools handle the data-to-chart pipeline differently.
CleanChart workflow
- Go to CleanChart — no signup
- Upload your file (CSV, Excel, JSON, or YAML)
- Select chart type from 25 options
- Customize colors, labels, axes
- Export PNG or SVG — done
Flourish workflow
- Create a Flourish account
- Create a new project
- Choose from dozens of templates
- Paste or upload CSV data
- Map columns to template fields
- Customize design settings
- Publish (embed) or download (paid plans only for high-res)
Flourish's workflow has more steps because it is more powerful for interactive output. If you need that power, the extra steps are worth it. If you just need a chart image, the extra steps are overhead.
Export Quality
CleanChart exports at 300 DPI by default, meeting the requirements for academic journal submissions, print publications, and professional presentations. SVG export is also available for vector editing in tools like Adobe Illustrator or Figma. For tips on preparing charts for publication, see our publication-ready charts guide.
Flourish's free tier limits export to low-resolution raster images. High-resolution PNG and SVG downloads require a paid plan. Flourish's strength is embed codes — you get a hosted URL and iframe snippet that renders the interactive chart on any webpage.

Frequently Asked Questions
Is Flourish better than CleanChart?
It depends on what you need. Flourish is better for animated, interactive visualizations embedded on websites. CleanChart is better for fast, privacy-first static charts exported as high-resolution images for reports, presentations, and papers. Neither tool is universally better — they target different outputs.
Can I use CleanChart instead of Flourish for free?
CleanChart lets you preview any chart for free without an account. Exporting requires chart tokens (starting at $7 for 10 charts). Flourish lets you create unlimited public charts for free but adds a "Made with Flourish" watermark. Both tools have free access with different trade-offs.
Does CleanChart support animated charts?
No. CleanChart produces static PNG and SVG exports optimized for print and digital documents. If you need animation, transitions, or hover interactivity, Flourish or a JavaScript library like D3.js is a better choice.
Which tool is more private?
CleanChart processes data entirely in your browser — nothing is ever sent to a server. Flourish uploads your data to its servers to host interactive visualizations. For sensitive, confidential, or regulated data, CleanChart eliminates the data-residency question.
What chart types does CleanChart have that Flourish does not?
CleanChart supports Gantt charts, bullet charts, Pareto charts, gauge charts, candlestick charts, step charts, combo charts, and sparklines — analytical chart types that Flourish does not offer. Flourish has bar chart races, parliament charts, and choropleth maps that CleanChart does not offer.
