If you found this article, you're probably doing repetitive things in your browser — filling forms, scraping listings, sending the same status updates — and wondering whether one of those "automate your browser" Chrome extensions actually works. We were curious too. So we installed five of the most popular ones, built the same three workflows in each, and compared.
This is the honest write-up. The TL;DR is that workflow automation in the browser hit a real inflection point in 2025-2026 because of AI Builders that draft workflows from prompts, but most tools haven't shipped that yet. Below: what we tested, what we picked, and why.
The five we tested
- BNOD (us) — visual workflow editor with an AI Workflow Builder
- Automa — open-source pioneer, MIT licensed
- Bardeen — playbook marketplace, SaaS-glue-heavy
- Browserflow — pro-grade scraping, IDE-feel
- HARPA AI — AI assistant on tabs (slash commands, not really a workflow editor)
We picked these because they're the top results for "Chrome workflow automation" + "browser automation extension" across the Chrome Web Store and Google. We left out simpler form-fillers (Magical, Text Blaze) because they aren't real workflow tools — they're shortcut expanders.
The three workflows we built in each tool
To compare apples to apples we built the same three workflows in every tool:
- Scheduled scrape — every morning at 9 AM, fetch the top stories from Hacker News and pop a notification with the top 3 titles.
- Form filler + screenshot — open a Typeform, fill it from a saved variable set, take a screenshot of the success page.
- Multi-tab data extract — open 5 Wikipedia article URLs in sequence, extract the first paragraph from each into a table, export as CSV.
Each workflow exercises something different: scheduling and HTTP and notifications; form interaction and screenshots; tabular extraction across multiple pages.
Quick ranking
| Rank | Tool | When to pick |
|---|---|---|
| 1 | BNOD | Modern editor + AI Builder + BYOK AI providers |
| 2 | Automa | You want open source and don't need AI assistance |
| 3 | Bardeen | You're glueing SaaS apps together, not scraping |
| 4 | Browserflow | Pro-grade scraping at scale, willing to pay |
| 5 | HARPA AI | You want a chat assistant per tab, not workflows |
The ranking is opinionated and assumes your goal is workflows (multi-step automations you build once and run many times), not chat-with-tab.
#1 — BNOD
What we liked: the editor uses n8n-style typed ports, so when you wire an HTTP response into a notification block, the variable picker shows you the exact shape of the JSON response — no guessing. The AI Workflow Builder drafted the Hacker News scrape correctly on the first try when we typed "every morning at 9, fetch top 5 HN stories and notify me." All three test workflows worked without manual debugging.
What we didn't like: the template marketplace is small (14 curated templates). It's MVP and the team is iterating fast, so this will grow — but today, Automa's community marketplace has more ready-made workflows.
Pick BNOD if: you want the most modern editor + AI assistance, you have a Gemini/Claude/OpenAI key, and you're okay with a smaller (but growing) template library.
#2 — Automa
What we liked: it's free, open-source, and has a large community marketplace where users have published hundreds of workflows. The block editor works as advertised and we got all three workflows running.
What we didn't like: no AI Builder — you build every workflow by hand. Active development has slowed in 2026 (most recent commits are bug fixes, not new capability). The variable system is untyped, so wiring data between blocks involves more trial-and-error than in BNOD or n8n.
Pick Automa if: open source is a hard requirement, you want the community marketplace, and you don't need AI assistance.
#3 — Bardeen
What we liked: the playbook gallery is enormous (200+) and many are SaaS-integration recipes (Notion, Airtable, Slack) that work out of the box if you connect the integrations. The "Magic Box" prompt-to-playbook feature exists.
What we didn't like: it's primarily aimed at SaaS-glue use cases — not scraping or general browser automation. Our Hacker News scrape required workarounds; the Wikipedia multi-tab extract needed paid scraper credits. Pricing escalates quickly past free tier.
Pick Bardeen if: you're connecting SaaS apps (Notion ↔ Slack, Airtable ↔ Gmail) and willing to pay for higher usage tiers.
#4 — Browserflow
What we liked: powerful at scale. The IDE-feel editor is the closest thing to Puppeteer for non-devs. Scraping just works, including pagination + structured extraction.
What we didn't like: the editor has a steep learning curve. Pricing is mid-market ($24-99/mo) — not for hobbyist use. We had no problems building the three workflows but the time to first success was 2-3x longer than BNOD or Automa.
Pick Browserflow if: you're scraping at production volume and willing to invest learning time + monthly subscription.
#5 — HARPA AI
What we liked: the AI chat on every tab is genuinely useful for one-off "summarize this page" or "extract the data points" requests. 400K Chrome users for a reason.
What we didn't like: it's not really a workflow editor — it's an AI assistant with quick-commands. You can't build a scheduled, multi-step workflow with branching logic. Two of our three test workflows weren't really possible in HARPA's model.
Pick HARPA if: you want an AI overlay per tab for ad-hoc summarization and extraction — not for building repeatable workflows.
What's actually changing in 2026
Three trends from this round of testing:
-
AI Builder as table stakes. BNOD ships it; n8n SaaS ships it; everyone else is catching up. Two years from now, "describe the workflow, the tool drafts it" will be expected. If your shortlist tool doesn't have it, factor in build time.
-
BYOK over hosted. Hosted AI costs add up fast. Tools that let you bring your own Anthropic/OpenAI/Gemini key (BYOK) win on cost transparency. Hosted AI in browser automation is the new "freemium that becomes expensive."
-
Typed ports. The shift from string-blob variables (Automa-style) to typed ports + schema trees (n8n / BNOD) makes editor UX dramatically faster — fewer wiring mistakes, instant feedback. Tools that haven't moved here yet are showing their 2021 architecture.
Our pick
We're biased — we built BNOD. But the reason we built it is that none of the existing tools combined a modern typed editor + AI Builder + BYOK providers in one extension. If we're wrong and another tool gets there in 2026, we'll update this list.
Install BNOD from the Chrome Web Store to try it. It's free during MVP — bring your own AI key (Gemini has a free tier with no credit card).
