Hi Mom :)

[Sean @v1rerra]

"Agents in dialogue, working toward your conditions."

That's Parlance — a free, no-code visual workspace
for multi-agent Claude workflows.

Two weeks. Five open-source tools. This is the
last one. And the biggest. 🧵

[Sean @v1rerra]

Runs entirely in your browser.
BYOK — key never touches our servers.
Free. Open source. MIT.

The full suite built in 2 weeks:
— Reality Check
— Singularity Workspace
— LoopLens
— Claude Batch
— Parlance

[Sean @v1rerra]

Targeted feedback — Overseer names the failing
agent. Only it and its downstream re-run.

No code. No YAML. No JSON. Just a canvas.

[Sean @v1rerra]

29 tests · 95 assertions · 10 real bugs found
and fixed — each with a regression test.
Exports JSON, CSV, or TXT.

Single HTML file. No build step. No backend.
Free and open source (MIT).

I kept hitting Claude's rate limits running
spreadsheets row by row.

So I built a queue that paces them automatically.

It's a single HTML file. No npm install. No server.
Open it in a browser and it works. 🧵

[Sean @v1rerra]

Upload a CSV or Excel file. Write a {ColumnName}
template. Only the columns you reference get sent
— 70–80% fewer tokens than dumping the full row.

Set an interval (1–180s). Press Start. Walk away.

Retries on 429s. Respects retry-after header.
AbortController on Stop.

[Sean @v1rerra]

Every other cost tool (Langfuse, Helicone,
Braintrust, W&B) is post-hoc. They tell you
after.

LoopLens tells you before.

Free. Open source. Zero API calls. Works offline.

Ran a 30-iteration agentic loop simulation.

Claude Sonnet 4.6 · 4 subagents · web search
+ code execution.

Estimated cost: $39.96.
Same loop on DeepSeek V4 Flash: $1.85.

95% cheaper. Before running a single API call. 🧵

[Sean @v1rerra]

It also caught:
— Context window hits limit by iter 30
— Sliding window saves 85%
— DeepSeek auto-caching = 47x cheaper prefixes

[Sean @v1rerra]

Free. Open source. Local first.

No account. No subscriptions. Everything on your
machine. Works offline. Windows desktop app too.

Free alternative to Notion, Miro, and Monday.

Most productivity tools force you to pick one view.

Notes app. Kanban board. Mind map. Timeline. All
separate. All out of sync.

I built something different. 🧵

[Sean @v1rerra]

Singularity Workspace — one dataset, four views:

🎨 Canvas — infinite node graph, connect anything
📋 Kanban — custom columns, drag and drop
📅 Timeline — chronological event mapping
📊 Table — sortable, click to jump to canvas

Change one. Updates everywhere. Instantly.
