Octo × Open-source alternatives PT Request an assessment

Octo for open-source tools around Illustrator

Nine hundred PNGs without opening any program, and a sample compared before any switch. Who decides is design.

Inkscape exports PNG, plain SVG and PDF from the command line, in a single process for the whole batch. Scribus lays out pages and exports PDF/X. CairoSVG and svgo convert and clean SVG on a server. Octo uses these tools at the edges of the work, always in a new folder and with the version recorded, and takes the compared sample to whoever is accountable for the artwork. Creation stays in Illustrator.

What Octo does with open-source tools.

Six possible deliverables, drawn from the assessment. None touches the source file, all check the result by content, and all go to review by whoever is accountable for the piece.

Task matrix

Each repetitive task with volume, today's tool, candidate alternative, version, license, source and risk.

Deliverable: matriz_ferramentas.csv with a decision per task

Headless Inkscape batch

Action script for a single process in shell mode: PNG at several widths, plain SVG and PDF, never over the source.

Deliverable: inkscape_lote.sh and the batch log

inkex extension

The same command in the editor menu and on the action line: prefix ids and fix references, rejecting an invalid prefix.

Deliverable: prefixar_ids_inkex.py (the .inx is done at installation)

Catalog in Scribus

Scripter lays out the pages with each product's SVG and copy, saves the .sla and generates a proof PDF; PDF/X stays in the dialog.

Deliverable: scribus_catalogo.py and catalogo_PROVA.pdf

Server-side conversion

CairoSVG turns system-generated SVG into PNG and PDF, logs errors per file and checks the signature of each output.

Deliverable: converter_cairosvg.py and registro.csv

Compared sample

Illustrator reference and open-source candidate, pixel by pixel, with a difference image for the designer to look at.

Deliverable: comparar_renders.py and comparacao.csv
02

Eight arms, one compared task.

The same Octo cycle, applied to open-source tools. Each arm has a narrow role; the people approve the sample, the proof and the switch.

  1. Discovery

    Surveys the tasks

    Repetitive tasks, monthly volumes, versions installed on each workstation and the collection by format.

  2. Data

    Writes the matrix

    Task, tool, version, license and source; manifests and comparison reports, versioned.

  3. Security

    Protects the source

    Source read-only, no overwriting, versions with security flaws fixed, care with macOS.

  4. Architecture

    Chooses by task

    Editor, a script inside the application or the command line on a server, depending on the volume and who receives it.

  5. Development

    Writes action files and scripts

    Inkscape action file, inkex extension, Scribus script and converter, with the source of each option noted.

  6. Review

    Checks by content

    Count, header of each output, manifest and comparison table. The visual comparison belongs to design.

  7. Release

    Prepares the delivery

    Checked folder and report. Sending to the website or the printer is approved by a person.

  8. Documentation

    Records what holds in your environment

    Versions of each tool, decisions per task, who approved each sample and what changed between versions.

Octo does not switch anyone's tool on its own or overwrite files. It does not approve drawings, decide the print PDF or move creation out of Illustrator.

03

Each task, its own tool.

The criteria Octo uses to choose, with the documented limit of each path.

TaskTool and pathNote
PNG at several widthsInkscape, --shell or --export-widthExporting suppresses the interface
Plain SVGInkscape, --export-plain-svgNo Inkscape namespaces and no RDF

From the measured task to the chosen tool.

Three steps. Each one only makes sense after the previous one has shown results on your team.

A proposal, not a promise

Matrix and versions

Octo surveys the repetitive tasks and the installed versions, without changing anything in the work.

  • Real volume per task
  • Versions with the flaw fixed
  • macOS workstations identified
Benefit: know where the repeated clicking is
2 Next

Compared sample

One chosen task runs down both paths, and design sees the table and the differences.

  • Illustrator reference
  • Open-source candidate
  • Decision recorded
Benefit: decide with the sample in hand
3 Later

Batch in production

The approved task becomes a batch: Inkscape in shell mode, CairoSVG on the server or Scribus for the catalog.

  • Nothing overwritten
  • Log of every output
  • A sample with every new version
Benefit: the whole library without opening a program

What Octo does and what stays with you.

Octo prepares everything, but it does not sign. The document of record stays with whoever is accountable for it.

Octo prepares

Surveys, calculates, organizes and generates the documents: files, artboards, proofs and reports.

Deliverable: material ready to check

Your team checks

The client or the art director checks what Octo delivered before approving. If something doesn't add up, it goes back to Octo with the correction.

Step: review by the approver

Who approves

Octo does not approve the artwork. Artwork carries no legal signature: approval of the artwork and the proof stays with the client or the art director.

Approval: client or art director

Sources.

Official pages of Inkscape, Scribus, CairoSVG, svglib and svgo, and the Illustrator what's-new page as a version reference, consulted on Oct 31, 2026.

Open-source tools where they fit, with a compared sample before any switch.

The assessment starts with the matrix of repetitive tasks and a sample of one of them, run down both paths. You get the volume, what matches, what doesn't and the questions only your team can answer, and you decide with that in hand.
